The M220Z1-L03 model is a 22 inch wide TFT-LCD module with a 4-CCFL Backlight Unit and a 30-pin 2ch-LVDS interface. This module supports 1680 x 1050 WSXGA+ (16:10 wide screen) mode and displays up to 16.7 million colors. The inverter module for the Backlight Unit is not built in.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association (VESA) and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal present. When there is no video input signals this monitor, following a time-out period, will automatically switch to an OFF mode. This reduces the monitor's internal power supply consumption. After the video input signal is restored, full power is restored and the display is automatically redrawn. The appearance is similar to a "Screen Saver" feature except the display is completely off. The display is restored by pressing a key on the keyboard, or clicking the mouse.

Troubleshooting by the Checksum

Diagnosis of trouble by the checksum is neither reliable nor convenient.
You can only use the checksum of the current direct-view TV to determine whether the software is corrupted or not.
The Checksum value is determined according to the version of the software loaded on the set.
Therefore, you can determine whether the software has been properly downloaded, if you know the correct checksum for that version of the software.
You can check the checksum according in the following order.
Factory Mode → Checksum → Enter → Output Checksum (e.g. 0xab2b)

Checksum Examples
T-SIXPEANM -1000.0 Checksum = XXXX

General Adjustment
In general, a color TV can provide ideal visual quality by adjusting the basic settings such as the vertical size, horizontal size, focus, etc.
Display a black and white picture on the screen to check if the picture is clearly displayed.

The system is a low to mid end; 22” 1680 x 1050 TFT TV solution basically for EU market with VCT4913G microcontroller / video audio processor chip on a 2-layer PCB. Since the target market is EU, the first release of the TV will support PAL/SECAM B/G/D/K/I/L/L’. The target panel is 22” W 1680 x 1050 TFT-LCD panels. A DVD loader is used to read DVD content and a DVB-T module card is used to support DVB-T.

Inputs
• 1xTuner (both analog and DVB-T)
• 1xDVD
• 1xScart
• 1xPC (VGA)
• 2xHDMI (optional)
• 1xBack AV (optional)
• 1xSIDE YPBPR (optional)
Outputs
• Speaker (stereo, 2x4 Ω, 2x4Watt)
• Headphone (stereo) (optional)
• Audio line out (stereo and mono) (optional)
• DVD/DVB-T coaxial SPDIF out(optional)

The system uses 17MB29 chassis.

17MB29 main board consists of two major blocks. The first block is analog front-end and this block is handled by VCTI chip that is highly multifunctional. VCTI performs Tuner IF demodulation, CVBS, RGB, SVHS and audio input selection and processing. The audio processor (MSP) supports equalizer, tone control, volume control, AVL, surround effect etc. The video processor (VSP) handles video processing such as color standard detection and demodulation, picture alignment (brightness,
contrast, color etc.). The IC also has a teletext decoder with fastext memory. The processed video output is sent to MST-TSUMU38BF, scaler/deinterlacer in RGB format together with a composite sync. The TV tuner is PLL controlled symmetrical IF output type. The IF signal is filtered by a single SAW filter. Inter-carrier sound demodulation is performed by the system. After the SAW filter block, IF signal is processed by VCTI IF demodulator. Audio signal is digitally filtered in the IF demodulator block. The same IF signal is buffered and sent to DVB-T module card, tdm1300.Since VCTI can handle all the audio processing, there is no need for additional audio processor solution on the board.

MSP has two audio inputs which are assigned to the Scart in L/R and Audio Switch L/R output.
MSP has three audio outputs which are assigned to the headphone amplifier L/R input, audio amplifier L/R input and Audio switch L/R input. The board employs MP7721 and TDA1308 to drive speaker and headphone outputs, respectively. Switching control for other audio inputs and outputs (HDMI, Back AV, PC, DVD, and DVB-T) is achieved by an I2C controlled audio switch (TEA6422).

MST-TSUMU38BF has two ADC inputs. First ADC input is assigned to the VCTI RGB output.
Other RGB/YPbPr inputs are multiplexed for the second ADC input. HDMI receiver ANX9021 analog output, VGA RGB input and the synchronization signals are multiplexed by a primary RGB switch (PI5V512). MST-TSUMU38BF has an embedded LVDS transmitter. There are three PWM output ports.
PWM0 is assigned to analog/digital dimming control for the backlight, PWM1 is used for backlight on/off and panel logic power supply on/off control and PWM2 is used to control PC/HDMI switch IC (PI5V512).
Power stage
The DC voltages required at various parts of the chassis and inverters are provided by a main power supply unit and power interface board. IPS generates 12V and 5V DC supply. Power stage which is on-chasis generates +12V for audio amplifier and 5V stand by voltage and 33V, 12V, 5V, 3.3V and 1.8Vsupplies for other different parts of the chassis.

TDM1300 board has no tuner on it. Instead, the tuner of 17MB29 is used for both analogue and digital reception. Tuner is controlled by either the 17MB29 microcontroller (VCTI), or TDM1300 board microcontroller. The IF (intermediate frequency) output of the tuner is sent to TDM1300 board for digital reception.

LVDS connector

This product include AC-DC flyback converter, DC-DC converter and DC-AC half bridge converter. There are two option whose total output power are 52W and 55W. This system does not have PFC (Power Factor Correction) coil.

Microcontroller/Video&Audio Processor (VCT4913G)
VCTI49xy is composed of microcontroller, video proccessor, display and deflection processor, sound proccessor and IF blocks.

VCTI49xyl family has two package types; PSSDIP88 and PMQFP144. PSSDIP88 package is chosen because of its convenience in the soldering process. PSSDIP88 package has two versions; 1 and 2. PSSDIP88-2 package is the “pinning mirrorred” version of PSSDIP88-1 and is preferred to be used for layout compatibility.

Scaler/De-interlacer (MST-TSUMU38BF)
The TSUMU38BF is total solution graphics processing ICs for LCD displays with panel resolutions up to XGA and WXGA+ / SXGA+ respectively. They are configured with a high-speed integrated triple-ADC/PLL, a high quality display processing engine, and an integrated multi-purpose output display interface that can support all major panel interface formats. To further reduce system costs, the MST517A-M also integrates intelligent power management control capability for green-mode requirements and spread spectrum support for EMI management.
The TSUMU38BF also incorporates a new Dynamic Frame Rate(DFR) generator for the digital output video to the display panel that preserves the advantages of a fixed output clock rate , while eliminating the output end of frame short-line.
MST has a built-in OSD generator with 291 character font programmable RAM. OSD generator supports 2/4/8 multi-color fonts, 8/16/256 color palette and 1K code attributes.

Display of a fixed picture for a long time may cause a permanent after-image on the screen, as commonly called “ghost shadow”. The degree of the after-image varies with the maker of LCD screen. This phenomenon doesn’t represent failure. This “ghost shadow” may remain in the picture for a period of time (several minutes). But when operating it avoid displaying still picture in high brightness for a long time.

– Op. Hours. During the life time cycle of the TV, a life timer is kept. It counts the normal operation hours, not the Stand-by hours. The actual value of the life timer is displayed in SAM in decimal value. For every two startups the counter increases by one. Min. 5 digits are displayed in decimal digits. In detail:
• Every 2x cold start-ups, to display a picture, increases the counter by 1 (i.e. interrupt the mains supply 2x while the set is ON).
• Every 2x warm start-ups (from Stand-by), to display a picture, increases the counter by 1.
• Every hour of normal operating increases the counter by 1 (i.e. if a set is continue ON for 2 hours,then increase the counter by 2).
• Stand-by hours are NOT counted.
– Main SW ID. Displays the loaded main SW version.
– Error Code x (where “x” is 1 to 5). The most recent error is displayed at the upper position (for an error explanation see section 5.4 Error Codes).
• Clear Codes. When “arrow right” is pressed and then the “OK” button is pressed, the error buffer is reset.

Error Codes

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from top to bottom (or left to right), new errors are logged at the top/left side, and all other errors shift one position to the bottom/right.

When an error occurs, it is added to the list of errors, provided the list is not full. When the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained).
To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation/
There is a simple blinking LED procedure for board level repair (home repair) the so called LAYER 1 errors, next to the existing errors which are LAYER 2 errors:
• LAYER 1 errors are one digit errors
• LAYER 2 errors are two digit errors.

When is LAYER 1 or 2 available
• In SDM mode: When SDM is entered via Remote Control code, LAYER 2 is displayed via blinking LED.
Error display on screen
If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g. a fault in the protection detection circuitry can also lead to a protection).
In case of non-intermittent faults, clear the error buffer before starting to repair (before clearing the buffer, write down the content, as this history can give significant information). This to ensure that old error codes are no longer present.

How to Read the Error Buffer
Use one of the following methods:
• On screen via SAM (only when a picture is visible). E.g.:
– 000 000 000 000 000: No errors detected
– 017 000 000 000 000: Error code 17 is the last and only detected error.
– 015 017 000 000 000: Error code 17 was first detected and error code 15 is the last detected error.
• Via the Blinking LED procedure.
• Via ComPair.
How to Clear the Error Buffer
Use one of the following methods:
• By activation of the “Clear Codes” command in the SAM menu.
• With a normal RC, key in sequence “062599” followed by “OK”.

Software Upgrading

Main Software Upgrade
In “normal” conditions, so when there is no major problem with the TV, the main software and the default software upgrade application can be upgraded with the “upgrade.bin”. This can also be done by the consumers themselves via the Software Update Assistant in the user menu (see DFU), but they will have to download their software from the commercial Philips website.

Copy the “upgrade.bin” file to the root of the USB stick.
2. Power “off” the TV and remove all memory devices.
3. Insert the USB stick that contains the downloaded software upgrade.
4. Switch “on” the TV, and activate the Main menu with the “Menu/House” key on the remote control.
5. In the Main menu, go to the “Software update” item.
6. Press “OK” key to go to the sub-menu.
7. Select “Local updates” in the sub-menu and press the “OK” key to enter the Software Update application.
8. You will be prompted to cancel or to proceed with the software updating.
9. To proceed, select “Update” and press the “OK” key to enter the next menu. In the next menu select “Start” and press “OK” key to start the software update.
10. Upgrading will now begin and the progress of the updating will be displayed. After the software updating is completed, the TV will automatically restart.

Stand-by Software Upgrade
In this chassis it is not possible to upgrade the Stand-by software via a USB stick or ComPair. Please order a preprogrammed device via the Philips Spare Part web portal.

Upgrade HDMI EDID NVM
To upgrade the HDMI EDID, pin 7 of the EDID NVM [1] has to be short circuited to ground.

Upgrade VGA EDID NVM
To upgrade the VGA EDID NVM, pin 7 of the EDID NVM [2] has to be short circuited to ground.

Display code
Changing the display option code via a standard RC
Key in the code “0 6 2 5 9 8 MENU x x x” (where x x x is the 3 digit decimal display code of the used display *).
• Keep the RC close to the IR receiver, and make sure the LED blinks when entering a code.
• Key in all codes in one sequence, without pauses.
If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialised first (loaded with default values). This initialising can take up to 20 seconds.

This display code can be found on the side sticker and/or on the rear sticker.

Option codes
Select this sub menu to set all options at once by selecting the correct model number. The so-called “Project ID” represents a number of different options, all related to that model number.
By toggling the “arrow left/right” buttons on the RC, the correct model number can be selected.
• After changing the option (or Project ID), save it by leaving the sub menu via the “Menu/House” button on the RC.

• The new option setting is only active after the TV is switched “off/on” with the mains switch (the NVM is then read again).

Reset of Repaired SSB
When a repaired SSB will be used in an other TV, it is very important that the correct info is written into the NVM w.r.t. 12NC of the SSB, production serial number of the TV, 12NC of display and PSU, etc.
To set all this, the ComPair tool can be used, or the NVM can be edited directly via the NVM editor (in SAM). Find below the addresses of these items. Use the decimal values.
In case of a display replacement, reset the “Operation hours” to “0”, or to the operation hours of the replacement display.

IPL42L PSU [Power Supply Unit]

The key component ICs are:
• Stand-by power supply IC: FSQ510 (Fairchild).
• PFC control IC: L6562 (ST).
• 24V PWM control IC: FA5571N (FUJI).
• Inverter high voltage control IC: OZ9926 (O2).

Fault Finding
Normal PSU working order:
• Connect the 220V AC power plug.
• The 3.3V Stand-by power supply (Stand-by uP U801) will start. This is a “single-ended fly-back regulator”. For a good functioning of this part, check the availability of 1.25V on U803 (TL431).
• On connector P802, signal line “PS_ON” will go “high” (3V3) and relay K801 will be activated.
• Also capacitors C811/C812 will be charged, supplying IC806 with electricity. This will start the PFC circuit and generate the +24 V control.
• Now, IC805 will start, and will generate the 24V output.
• On connector P802, signal “DIM” sets the PWM dimming status. • On connector P802, when signal “BL-ON” goes “high”, the high voltage Inverter (IC901, OZ9926A) will start.

The Blinking LED Procedure (LAYER-2 codes)

Some errors need several minutes before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onward, and then check if the front LED is blinking or if an error is logged.

The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over time, an error buffer is available that is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the LED pulse with as many pulses as the error code number, followed by a time period of1.5 seconds in which the LED is “off”. Then this sequence is repeated.
E.g. error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence the LED will be “off” for 1.5 seconds. Any RC command terminates this sequence.
Displaying the entire error buffer
The entire error buffer can be displayed when service mode “SDM” is entered (by remote control command 062596<MENU>). When in protection, this sequence will not work, but than LAYER-1 error code should suffice.
In order to avoid confusion with RC signal reception blinking, this blinking procedure is terminated when a RC command is received.

How to Activate
Use one of the following methods:
• Activate the CSM. The blinking front LED will show only the latest LAYER-1 error.
• Activate the SDM. The blinking front LED will show the entire contents of the LAYER-2 error buffer.

In case of starting from blanked flash / eMMC, it’s necessary to use “Blank upgrade” to update the SW.

In case of starting from blanked flash, it’s necessary to write “emmc.upm” file via factory copy in advance.

OAD Stream//please delete it ,this mathine did not need this function to update software
To manage quicker mass reflashing on predefined DVB Channel, some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe', dsmmerge.exe …) from Intel byte Inc. might be necessary to create appropriate DVB SSU image. Over some predefine settings such as repeated data block insertion, null packets size, … that are controllable in configuration file, here below are mandatory OUI entries structure to prepare DSM-CC carousel image format:
- export CUST_OAD_OUI 0x001C50
- export CUST_OAD_HW_MODEL 0x5395
- export CUST_OAD_HW_VERSION 0x0000
- export CUST_OAD_SW_MODEL 0x0001
- export CUST_OAD_SW_VERSION 0x00
OAD reflashing is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and warm-start.

UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with itsUSB port well connected to suitable UART device or an IR emitter device correctly facing up TV (see below “Product Assembly - section 2.0” how to activate “Factory key”).
The UART parser engine is enabled by sending following command “0xE2” from host to TV within following presets 115200/8/n/1.
Once initialized, “PS” caption is toggle displayed on bottom left screen (“S” like Serial).
To communicate with TV depending on SIACP revision layout implementation, you need to fulfill UART/IR commands protocol and format described on enclosed SIACP requirements document.

Project ID Modification
There are different IDs stored into thee MMC depending on different Panels settings and Models features, but there is only one key branching Project ID that includes all. So, it’s not recommended to modify Pane ID with Hyper terminal as other ID features may not change.
To modify Project ID, you need to go through “Factory menu > Other > Project ID”, then spin left or right with RCU “◄/►” key” keys to suitable ID (Project name is dynamically refreshed).It is necessary to press “OK” key for saving the setting.

How to change the Project ID with RCU

Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected, plug all external generator devices to relevant below inputs/outputs using respective test patterns format to check picture and sound quality.

Audio tones can be defined by the factory (ie: 1KHz & 3KHz, sweep, …).

Picture video formats can be changed by the factory according to their own standard.

As SoC as built-in A/D self-calibration mechanism, there’s not any ADC to perform.

DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for HDMI). CEA Timing Extension structure has been extended to support all 3D capable timings.
All HDMI structures have their own BIN profile which are part of main SW and uploaded at power-on into soc chipset: For EDID check, it’s needed to check whether the correct EDID is downloaded by checking corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the released EDID bin file.

HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set by connecting suitable generator.

LAN and WLAN Test(MAC address and Device/User ID codes)

Here are some representative codes examples:

Device ID: 6fa0806936a0ada733262a3f8e8595d5586ce5cb

User ID: 111382090

MAC address: 00:1C:50:E2:B1:EC

MAC Address Upgrade (IPv6)
MAC can be set using UART commands described on enclosed SIACP requirements (rev. v3.9).
- Writing MAC command <0xB3>, Data length <6>, Data type <HEXA> (see below command example from above MAC code)
<AA 0B B3 00 1C 50 E2 B1 EC 36 78>

How to upgrade MAC Address using USB

Device ID (DID)
Purpose is to allow Other Newtork Download (OND) and further specific Services via dedicated abroad portal (UK tbc).4 At final, when TV may ask for portal connection, there’ll be Device ID matching control sent by host (TV client) to ensure total integrity.

For such, specific DID (40 bytes) needs to be paired and overwritten into memory for internal client encryption.
All DID and MAC codes have to download from portal local service via suitable factory workstation LAN system.
Then during production lot, it’s necessary to send/write all those codes to each TV.
DID codes can only be set using UART commands described above on enclosed SIACP requirements (rev. v3.9).
- Writing Device ID command <0xB2>, Data length <32>, Data type <ASCII> (see below command example from above DID code)
<AA 25 B242 45 34 46 32 35 35 42 42 44 31 30 36 42 43 38 46 38 30 36 41 45 34 35 36 33 35 30 44 39 31 464893>

LAN Test
A rough LAN test can be done by connecting DHCP server to TV’s RJ45 and check that IP, subnet mask, DNS, … addresses are visible on “User menu > Network > Internet connection(On) > IP settings”.
More in-depth test can be performed faster using suitable UART/IR commands following SIACP requirements. SW will internally manage Network ID (NID) flag controlling all MAC/DID/UID integrity to facilitate PA screening further.

Stand by/Start-up Operation (P/A board)

When the TV is plugged in, the power board outputs 5V for standby power. Upon receiving this voltage, the micro (IC8000) outputs the TV_SUB_ON command.
When the power supply receives the TV_SUB_ON signal, it outputs 2 different voltages:
P15V to the A board on pins 1, 2, and 3 of connector P2.
24V to the LED backlight power board on pins 7, 8, and 9 of connector P4. This voltage is not used at plug-in.
When the power-on button is pressed and the A board is ready to turn on the display, IC8000 of the A board outputs the Backlight-on command to LCD Module.

Start up operation _ Step 1

When the TV is plugged in, the rectifier circuit produces a DC voltage that travels through the PFC circuit directly to the power switches Q7301 and Q7302. A separate DC voltage, approx. 40V, produced by D7104 and D7105 serves as start-up voltage to pin 1 of the oscillator IC7301. When the voltage on pin 1 rises up to a predefined value, IC7301 starts to oscillate and output switching pulses to Q7301 and Q7302. As current flows through the winding of T7301, output voltages are generated by the transformer. One of these voltages, VCC, is used to power pin 10 of IC7301 .
When the power supply starts up, 6V is created by D7407/C7514. This voltage goes to IC7502 which is a 5V regulator. The start command for this regulator originates at pin 3 of IC7301.
This pin is internally grounded in normal state and the information is carried to the secondary side by PC7303. Finally there is around 2.4V on pin 3 of IC7502 to start its operation. Then 5V is output at pins 1 and 2 of the IC.
This voltage (STB5V) is provided to the A board via pin 5 of connector P2.
So when the TV is plugged in, STB5V is provided to A board without an external trigger signal.

Start up operation _ Step 2

The STB5V from pin 5 of connector P2 is applied to the Analog ASIC (IC5000) to supply power to the Main CPU/PEAKS LD4 (IC8000) on the A board. The Analog ASIC (IC5000) converts the STB5V to STB3.3V and STB1.2V. These 2 voltages energize and prepare the microprocessor (CPU) for program execution. The STB3.3V from the Analog ASIC (IC5000) is also applied to the remote control receiver and the power LED on the K board through pins 5 and 10 of connector A10.
Upon energizing, IC8000 automatically outputs the TV _SUB_ON command for approximately 12 seconds. This command triggers the output of the P15V source (not shown in the drawing) to the A board, but the red LED does not light.
The A board performs a self-check operation to determine its communication status. If a defect is encountered, the unit shuts down and possibly displays a blink code. If all is well, the unit goes to the standby mode.
When the power on command from the power switch, the remote control receiver or Viera Link is provided to IC8000 PEAKS LD4, the “TV_SUB_ON” command (2.4V) is output. The “command is provided to the power supply board via pin 7 of connector P2.

Start up operation _ Step 3

When the power board receives the TV_SUB_ON signal from IC8000 via pin 7 of connector P2, it outputs 2 different voltages:
1.P15V to the A board on pins 1, 2, and 3 of connector P2.
2.24V to the LED backlight power board on pins 7, 8, and 9 of connector P4.
This command is carried to the primary side of the power supply by PC7302. This voltage turns on the transistor Q7303 to provide a reference voltage from pin 6 to pin 5 of IC7301. Therefore the operation of IC7301 changes the switching frequency from standby state to increase the output voltages.
The TV_SUB_ON command also turns on Q7202 to provide power and turn on the PFC circuit. As a result, the PFC starts to operate and the output voltages from the transformer T7301 start to rise until the moment IC7401 starts to operate. This IC monitors the 16V output on the secondary side of the power supply. The output of IC7401 is provided to pin 4 of IC7301 by PC7301. IC7301 adjust the switching frequency by this feedback signal. The circuit is designed to maintain a stable DC output of the power supply.
The TV_SUB_ON signal also switches on the transistors Q7402 and Q7403 to output the P15V and 24V output voltages to other boards.
The 24V is provided to the LCD Module ( LED Backlight Power Supply).
The P15V is provided to the A board.

Start up operation _ A board (SUB voltages)

The P15V from the P board enters the A board via pins 1, 3 and 5 of connector A02. It is applied to the Analog ASIC IC5000 and other ICs (Voltage regulators) to generate the SUB-Voltages used for signal processing operation.
The SUB1.1V, 1.5V, 1.8V, 3.3V, 5V, HDMI3.3V and USB5V are created.
Each voltage regulator is activated by a DCDCEN command created from the P15V source.
So the presence of the P15V source on the A board causes each of the SUB-voltage regulator ICs to output a DC voltage.

Start up operation _ A board (OVP circuit)

The Sub voltages are monitored for over-voltage condition. If any of these voltages increases above a predetermined level, the OVP circuit will be triggered by getting pin 7 of IC5000 to go high.
When pin 7 goes high, the TV_SUB_ON voltage connected to pin 8 is grounded. This disables the circuit that generates the P15V and 24V on the power supply.
If any abnormality occurs with P15V, the DCDCEN circuit inside IC5000 provides a DC output to turn on the switch at pin 11. This in turn disables the output of the SUB-Voltage regulator ICs (IC5400, IC5420, IC5440, IC8100 and IC8101).
When an over voltage condition is detected at plug-in the TV becomes completely disabled and the power
LED remains off.
When an over voltage condition is detected at power-on the TV becomes completely disabled and the power
LED remains on.

Start up operation _ A board (PNL,FRC voltage)

The P15V is also used to generate the PNL-Voltage and FRC-Voltages on the A board. IC5000 outputs the Panel VCC On2 signal. IC5300 uses this command to generate the PNL12V.
The PNL12V is provided to the T-con circuit of the LCD Module and ICs (Voltage regulator) to produce FRC-Voltages.
After that, IC8000 outputs the BL_ON command to the LCD Module through the P board. The BL_ON command turns on the LED backlight power supply of the LCD Module. If the backlight power circuit does not work normally, the BL_SOS signal communicates this information to IC8000. At that time, IC8000 stops outputting the TV_SUB_ON signal and blinks the red power LED 1 times.

TC-L47ET5 Connector Voltages)

Video Signal Processing

Video Process

The main function of the A board is to select and process one of the incoming video signals. IC8458 and IC4700 are switches that select USB and HDMI signals. The built-in WiFi module is connected using a USB type terminal.
Video input, Component Video Input, composite video output of the tuner and the other HDMI input are all connected to IC8000 for selection. The IC has interface circuits that converts each input signal into digital RGB . The data selected for viewing is then provided to the RGB process circuit within the same IC for processing.
The RGB Process section of the IC performs all picture control operations such as brightness, contrast, color, tint, etc. On Screen Display data such as channel numbers, Digital TV closed caption, and picture adjustments are mixed with the video data. After the process, LVDS (Low Voltage Differential Signaling) is output to IC9100. IC9100, the FRC (Frame Rate Converter) IC doubles or triples the frame rate to improve focus and eliminate blur.
The output signal is provided to the T-CON for display on the LCD screen.

TC-L47ET5 Upper LVDS Connector

A disconnected upper LVDS connector (TC02A) results in distorted video. The picture appears to be in the background with vertical white line in front.

When troubleshooting a distortion of this type, if the LVDS connector is in place, use the internal pattern generator to determine if the problem is in the A board or the T-CON. A normal T-CON generates pictures that are clean and smooth. Keep in mind, the T-Con is part of the panel. It cannot be replaced in the field.

Lower LVDS connector

When the lower LVDS connector (TC01A) is disconnected, The screen is dark blue with no video.
Use the internal pattern generator to determine if the problem is in the A board or the T-CON. A normal T-CON generates pictures that are clean and smooth. Keep in mind, the T-Con is part of the panel, it cannot be replaced in the field.

Panel Free Run Mode

When a picture problem is encountered, the internal test pattern generator may be used to determine whether the symptom is the result of a defective A board or panel.
The test pattern is displayed:

Panel Drive

1.The panel_VCC_ON command turns on the panel 12V regulator to power the T-CON circuit.
2. The PWM_ENB command turns on the PWM generator to produce the control signal for the LED backlight circuit.
3. The DISPEN command turns on the T-CON circuit to produce the column and row signals to drive the panel.
4. Since the T-CON determines the panel’s drive signals, the Bluetooth Left and Right signals are generated for transmission to the glasses.
5. The LVDS data is the video signal used by the T-CON to produce the column and row signals to drive the panel.
6. The IIC data is the communication line between the T-CON and the Main CPU. Data for the PWM signal is also provided through the IIC line.
7. The LED Driver Control signals, using customer’s OSD, CATS, or artificial intelligence, manipulate the backlight .

47WT50 & 47DT50 LED Backlight Control

The LED driver board receives 66Vdc and 16Vdc from the power supply via connector P4/LD4. The 16V source is used to bias the drive IC, IC9500. The 66V source is used bias the LED. The backlight On command from the same
connector starts the inverter drive signals.
The BL_SOS connection originates at IC8000, the system control IC located on the A board. IC8000 monitors the status of BL_SOS line to determine the state of the LED drive circuit. During normal operation, IC9500 pulls the BL_SOS line
low to inform IC8000 of the illumination of the LED. Should the drive circuit or an LED array inside the panel become defective, the BL_SOS line remains or goes high to inform IC8000 of the condition. The TV shuts down and the power
LED emits a one blink error code. The LED drive circuit is responsible for delivering the current needed to illuminate the panel’s LEDs. A total of 16 FETs are manipulated on/off by grounding pulses generated within IC9500. To adjust the brightness, the pulses are modulated to control the on and off time of the FETs.
Unlike other models, a PWM_EN command is provided to the T-CON by the system control IC. The actual PWM signals are communicated via the IIC bus line of IC8000. The PWM signals are provided to the LED drive circuit via the
connector LD3.

The 66Vdc source and grounding pulses are delivered to the LEDs via the connectors LD1 and LD4.
When the TV is displaying 3D images, the 3D_ON command is output from IC8000 to change the 66Vdc source of the power supply to 84Vdc.
Note:
Connector LD1 or LD2 disconnected = Brief (2 seconds) operation with video and sound , then shutdown with one blink of the power LED
Connector LD1 and LD2 disconnected = Brief operation with black screen and sound , then shutdown with one blink of the power LED
Connector LD4 Disconnected = Brief operation with black screen and sound , then shutdown with one blink of the power LED
Connector LD3 Disconnected = Brief operation with black screen and sound , then shutdown with one blink of the power LED.

Troubleshooting 1 Blink of the Power LED (WT & DT Series)

- Normal: BL_ON is high (3.3V) in Standby mode , BL_SOS is low (0V) (power On)
- Error : BL_ON is low (0V) in Standby mode , BL_SOS is high (3.3V) ) (power On)

BL_SOS is generated when a malfunction is detected by the backlight power board (LD). A logic High is sent to IC8000 of the A board via pin 10 of connector LD4, pin 1 of connector P4, pin 10 of connector P2 and pin 4 of connector A02.

Power LED Blinking codes troubleshooting

Troubleshooting 1 Blink of the Power LED (WT & DT Series)

P15V is supplied by the P board. If P15V is not available the power LED blinks 3 times (quick blink)

Troubleshooting 7 Blinks of the Power LED

This defect can only be caused by the A board.

IC5400 uses the P15V source to produce SUB3.3V.
If SUB3.3V is not detected by IC8000, the LED indicator will blink 7 times. This voltage is only available when IC5400 is activated by the DCDCEN command sent from IC5000.

Troubleshooting 9 Blinks of the Power LED (ET5 Series)

The audio amplifier is powered by the P15V from the P board. If the amplifier works abnormally due to a short-circuit or an overload by one of the speakers, the SOUND_SOS signal will go high level and be detected by IC8000. The TV
shuts down and the power LED blinks 9 times.

Troubleshooting 9 Blinks of the Power LED (DT & WT Series)

The audio amplifiers are powered by the P15V from the P board. If the amplifiers work abnormally due to a short-circuit or an overload by one of the speakers, the SOUND_SOS signal will go high level and be detected by IC8000.
The TV shuts down and the power LED blinks 9 times.

Troubleshooting 10 Blinks of the Power LED

Using the P15V source, IC5300 produces and regulates the PNL12V. If the voltage PNL12V is not detected, the unit shuts down and the LED indicator blinks 10 times. This voltage is only available when IC5300 is activated by the PANEL_VCC_ON command sent from IC8000.

The Power LED Remains in Standby Mode

If one of regulated voltages (P15V, SUB5V, SUB3.3V, SUB1.5V, SUB1.1V, USB5V) becomes excessive, the OVP circuit outputs a High to IC5000 to start the shutdown process. The TV_SUB_ON command goes low to place the TV in standby mode. The power LED indicator turns off. After unplugging and reconnecting the TV to the AC outlet, after power on, the screen may turn on for a short time and then goes back to standby mode.

The LED backlight does not turn on

The BL_PWM signal controls the brightness of the LED backlight. It is a PWM waveform sent by IC8000 of the A board.
This BL_PWM has an amplitude of 3.3V and a frequency of 120Hz.
- In standard picture mode, the average voltage of the BL_PWM signal is about 2.5V (about 80% ON, 20% OFF).
- In vivid picture mode, the BL_PWM signal has a maximum voltage of 3.3V (100% ON).
The BL_PWM voltage varies with brightness, the darker the screen, the lower the BL_PWM voltage.
If the BL_PWM voltage is maximum in vivid picture mode, but the LED backlight brightness is still significantly darker than that of normal condition, the Panel Module is damaged.

Samsung CS29B850F18XSV Chassis: KSDB(P)-CB1M – 29 inch CRT color TV

Basic Troubleshooting: Diagnosis of LED on the Front Panel

Light is On: This happens when the Master Switch is not pressed or the power cord is disconnected.

Light is Blinking: This happens when the power cord is disconnected.

Light is Off: The LED blinks, while the unit is starting up or the unit is turning off.

Troubleshooting by the Checksum
Diagnosis of trouble by the checksum is neither reliable nor convenient.
You can only use the checksum of the current direct-view TV to determine whether the software is corrupted or not.
The Checksum value is determined according to the version of the software loaded on the set.
Therefore, you can determine whether the software has been properly downloaded, if you know the correct checksum for that version of the software.
You can check the checksum according in the following order.
Factory Mode > Checksum > Enter > Output Checksum (e.g. 0xab2b)

Checksum Example
T-UR2PEANS-0001 checksum=2A0B

- Supplied Power: 5V, 8V, 33V
- RF Trouble Check: Check CVBS output
- AUDIO Trouble Check: Check SiF Signal output.

General Adjustment :
In general, a color TV can provide ideal visual quality by adjusting the basic settings such as the vertical size, horizontal size, focus, etc.
Display a black and white picture on the screen to check if the picture is clearly displayed.
If there are some ‘spotted’ points on the screen when displaying a black and white picture, degauss the screen using the degauss coil. If the spotted points remain, re-adjust the purity and the convergence.
This completes the basic performance examination.

The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must be the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X - RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. Refer to this service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits, take necessary corrective action. Carefully follow the instructions for + B1 volt power supply adjustment, and high voltage check to maintain the high voltage within the specified limits.

Protection Circuit

This TV set has a built-in power supply protection circuit.
It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality occurs during TV reception, the TV set goes to the standby mode.

When an abnormality occurs during TV reception, it causes pin 27 of the CPU to go continually Low voltage for about one second. The CPU detects that this has occurred and outputs the signal from pin 31 to switch off the power supply lines.

Releasing the protective circuit and restoring power supply

To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again via either the main power switch or the ON-OFF button on the remote control. This will work only if the power supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be restored and the circuit will have to be repaired.

Purity and Convergence Adjustment

CAUTION: The Convergence and Purity adjustments have been made at the factory. Readjustment should be made only after picture tube or deflection yoke replacement, following the steps below:

PURITY ADJUSTMENT
1. Demagnetise the picture tube and receiver using an external degaussing coil. When replacing picture tube or deflection yoke, mount deflection yoke and purity-convergence magnets assembly properly, see figures 1 and 4.
2. Turn Red and Blue guns off and provide only Green raster. Rotate Screen control to fully counterclockwise. Rotate Red and Blue Bias controls fully counterclockwise. Slowly rotate Green Bias control clockwise to produce Green raster.
3. Loosen the screw holding the Deflection Yoke and remove the 3 Rubber Wedges, and slide the Deflection Yoke fully forward.
4. Rotate and spread the Tabs of the two Purity Magnets to centre the vertical green belt in the picture screen. The Purity Magnets are also adjusted to obtain vertical centring of the raster.
5. Slowly slide the Deflection Yoke backward until a uniform green screen is obtained.
6. Check the purity of the red and blue screens for uniformity, turn off other colours to check this (use bias controls). Readjust the yoke position if necessary until all screens are pure.
7. Adjust each Bias control and screen control to obtain white raster. Refer to Gray Scale Adjustment. If part of the picture screen is coloured, adjust the Deflection Yoke position forward or backward slightly.

8. Tighten the mounting screw of the Deflection Yoke. Adjust Convergence next.
CENTRE CONVERGENCE ADJUSTMENT
1. Use a dot crosshatch pattern signal.
2. Turn Red and Blue guns on and turn off Green gun. Adjust the angle between the Tabs of the Four Pole Magnet 1 and 2, and superimpose the Red and Blue vertical lines in the centre area of the picture screen. Refer to figure.
3. Keeping the mutual angle of the Tabs of the Four Pole Magnet turn them together to superimpose the Blue and Red horizontal lines in the centre area of the picture screen. Refer to figure.
4. Turn Green gun on and adjust Six Pole Magnet 3 and 4 that the Green line superimposed on the Red/Blue lines. This is the same procedure used in steps 2 and 3.
Refer to figure.
OUTER AREA CONVERGENCE ADJUSTMENT
Slightly loosen the screw holding the Deflection Yoke. Adjust the Deflection Yoke to converge the detail in the outer area (left side and right side) of the picture screen by orbital movement of the front of the Yoke, then secure the Deflection Yoke in appropriate position by putting the wedges as illustrated. Tighten screw holding the Deflection Yoke.

Display Option Code Selection
When after an SSB or display exchange, the display option code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after such a repair.
To do so, press the following key sequence on a standard RC transmitter: “062598” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type. When the value is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed.
During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSB related (e.g. Model and Prod. S/N). Therefore, “Model” and “Prod. S/N” data is changed into “See Type Plate”. In case a call centre or consumer reads “See Type Plate” in CSM mode.

Software Identification, Version, and Cluster

The software ID, version, and cluster will be shown in the main menu display of SAM, and CSM.
The screen will show: “AAAAAB-XXX.YYY.MMM.TTT”, where: • AAAAA is the chassis name: TPL161E.
• B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.

• X is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 1 - 99 and AA - ZZ.
- If the main version number changes, the new version number is written in the NVM.
- If the main version number changes, the default settings are loaded.
• YYY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version number is written in the NVM.
- If the NVM is refreshed, the software identification, version, and cluster will also be written to NVM.

Service Alignment Mode (SAM) [Service Mode]

To activate SAM, use one of the following methods:
• Press the following key sequence on the remote control transmitter: “062596”, directly followed by the “INFO/OK” button. Do not allow the display to time out between entries while keying the sequence.
After entering SAM, the following items are displayed, with “SAM” in the upper right corner of the screen to indicate that the television is in Service Alignment Mode.

How to Navigate
• In the SAM menu, select menu items with the UP/DOWN keys on the remote control transmitter. The selected item will be indicated. When not all menu items fit on the screen, use the UP/DOWN keys to display the next/previous menu items.
• With the “LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.

Software Upgrading

It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a stand alone set. A description on how to upgrade the main software can be found in the DFU or on the Philips/support website.

Preparing a portable memory for software upgrade
The following requirements have to be met:
1. A personal computer connected to the internet.
2. An archive utility that supports the ZIP-format (e.g. WinZip for Windows or Stufflt for Mac OS).
3. A FAT formatted USB memory stick (preferably empty).
Note:
1. Only FAT/DOS-formatted memory sticks are supported.
2. Only use software update files that can be found on the philips web site.

Check the current TV software version
Before starting the software upgrade procedure, it is advised to check that what the current TV software:
1. Press the “1 2 3 6 5 4” button on the remote control to enter the CSM mode.
2. Use the up/down cursor keys to select “Current Main Software”.
If the current software version of the TV is the same as the latest update file found on philips/support website. It is not necessary to update the TV software.

Download the latest software
1. Open the internet page philips/support website.
2. Find information and software related to the TV.
3. Select the latest software update file and download it to the PC.
4. Insert the USB memory stick into one of the USB ports of the PC.
5. Decompress the downloaded ZIP file and copy it to the root directory of the USB flash drive.

Update the TV software
1. Turn the TV on and wait for it to boot completely.
2. Insert the USB memory stick that contains the software update files in one of the TV’s USB ports.
3. The TV will detect the USB memory stick automatically.
Then a window jumps out.
Note: If the USB flash drive is not detected after power up, disconnect it and re-insert it.
4. Select [Update] and press OK.
5. To proceed, In next menu select [Start] and press OK to start software updates.

6. Upgrading will now begins and the status of the updating progress will be displayed.
7. When the TV software is updated. Remove your USB flash drive, then select [Restart] and press OK to restart the TV.

Note:

• Do not remove the USB flash drive during the software update.
• If a power failure occurs during the update, do not remove the USB flash drive from the TV. The TV will continue the software update as soon as the power comes up again.
• If an error occurs during the update retry the procedure or contact the dealer.
• it is not recommended downgrading to an older version.
• Once the upgrade is finished, use the PC to remove the TV software from the USB portable memory.

Content and Usage of the One-Zip Software File
Below you find a content explanation of the One-Zip file, and instructions on how and when to use it. Only files that are relevant for Service are mentioned here.
• EDID_clustername.zip: Contains the EDID content of the
different EDID NVMs.
• FUS_clustername_version.zip: Contains the file downloaded which is needed to upgrade the TV main software and the software download application.
• NVM_clustername_version.zip: Default NVM content.

How to Copy NVM Data to/from USB
When copying data to and from a USB memory stick, the folder “repair” is used. When inserting an empty USB memory stick, and downloading data to the stick, the TV will create this folder.
When sending data from a USB memory stick to a TV, the intended data must be available in the “repair” folder.
Note that when copying EDID data to the TV, all necessary EDID files must be in this folder.

Error Codes

Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every:
• Activated (SW) protection.
• Failing I2C device.
• General I2C error.
The last five errors, stored in the NVM, are shown in the Service menu’s. This is called the error buffer.
The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.
An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED).
In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed.

How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/CSM (if you have a picture).

Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the last and only detected error
– ERROR: 034 013 000 000 000: Error code 13 was detected first and error code 34 is the last detected (newest) error
• Via the blinking LED procedure (when you have no picture).

In this chassis only “layer 2” error codes are available and point to problems on the SSB. They are triggered by LED blinking when CSM is activated. Only the following layer 2 errors are defined:

How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu
• By using the CLEAR command in the Factory mode:
• By using the following key sequence on the remote control transmitter: “062599” directly followed by the OKbutton.
• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset.

The Blinking LED Procedure

The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SAM, the following occurs.
• 1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.

How to Activate Blinking LED Procedure
Use one of the following methods:
• Activate CSM.The blinking front LED will show the layer 1 error(s), this works in “normal operation” mode or automatically when the error/protection is monitored by the standby processor.
In case no picture is shown and there is no LED blinking, read the logging to detect whether “error devices” are mentioned.

• Activate SAM. The blinking front LED will show the entire content of the LAYER 2 error buffer, this works in “normal operation” mode.

Guidelines Uart logging

Possible cases:
Uart loggings are displayed:
• We can conclude that the TV-set is starting up and that communication with the flash RAM seems to be supported. The processor is able to read and write in the
DRAMs.
• We can not yet conclude that flash RAM and DRAMs are fully operational/reliable. There still can be errors in the data transfers, DRAM errors, read/write speed and timing control.
Uart loggings report fault conditions, error messages, error codes and fatal errors:

• Some failures are indicated by error codes in the logging.
• I2C bus errors.
• Not all failures or error messages should be interpreted as fault. For instance the root cause can be wrong option codes settings.

TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.

Audio Amplifier
The Class D-IC U606 has a power pad for cooling. When the IC is replaced it must be ensured that the power pad is very well pushed to the PWB while the solder is still liquid. This is needed to insure that the cooling is guaranteed; otherwise the Class D-IC could break down in short time.

Display option code
Attention: In case the SSB is replaced, always check the Panel Code in CSM, even when picture is available. Performance with the incorrect display option code can lead to unwanted side-effects for certain conditions.

Software Alignments

Put the set in SAM mode. The SAM menu will now appear on the screen. Select RGB Align and go to one of the sub menus.
The alignments are explained below.
The following items can be aligned:
• White point.
To store the data:
• Press OK on the RC before the cursor is moved to the left.
• Select “Store” and press OK on the RC.
• Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a video generator to the RF input:
• EU/AP-PAL models: a PAL B/G TV-signal with a signal strength of at least 1 mV and a frequency of 475.25 MHz
• US/AP-NTSC models: an NTSC M/N TV-signal with a signal strength of at least 1 mV and a frequency of 61.25 MHz (channel 3).
• LATAM models: an NTSC M TV-signal with a signal strength of at least 1 mV and a frequency of 61.25 MHz (channel 3).

RGB Alignment
Before alignment, set the picture as follows:
White Tone Alignment:
• Activate SAM.
• Select “RGB Align.” and choose a color temperature.
• Use a 100% white screen as input signal and set the following values:
– “Red BL Offset” and “Green BL Offset” to “7” (if present).
– All “White point” values initial to “128”

In case you have a color analyzer:
• Measure with a calibrated (phosphor- independent) color analyzer (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a dark environment.
• Adjust the correct x, y coordinates (while holding one of the White point registers R, G or B on max. value) by means of decreasing the value of one or two other white points to the correct x, y coordinates. Tolerance: dx: ± 0.003, dy: ± 0.003.
• Repeat this step for the other color Temperatures that need to be aligned.
• When finished return to the SAM root menu and press STANDBY on the RC to store the aligned values to the NVM.

• Repeat this step for the other colour Temperatures that need to be aligned.
• When finished return to the SAM root menu and press STANDBY on the RC to store the aligned values to the NVM.

Display Adjustment
You can use the default values. The default values are average values coming from production.
• Enter SAM mode.
• Select a colour temperature (e.g. COOL, NORMAL, or WARM).
• Set the RED, GREEN and BLUE default values according to the values.
• When finished press OK on the RC, then press STORE to store the aligned values to the NVM.
• Restore the initial picture settings after the alignments.

Value	Cool (11000 K)	Normal (9000 K)	Warm (6500 K)
x	0.276	0.287	0.313
y	0.282	0.296	0.329

Option Settings

The microprocessor communicates with a large number of I2C ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence / absence of these MT5561 ICs is made known by the option codes.
Notes:
• After changing the option(s), save them by pressing the OK button on the RC before the cursor is moved to the left, select STORE and press OK on the RC.
• The new option setting is only active after the TV is switched “off” / “stand-by” and “on” again with the mains switch (the NVM is then read again).

Option Code Overview
Enter SAM mode to check the option codes. they could be edited in the NVM.

Display Code Overview
Press the following key sequence on a standard RC
transmitter: “062598” directly followed by MENU and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see column “Display Code”. After resetting the Display Code, restart the set immediately.

Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB.
A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the “NVM editor” and “Dealer options” items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM.

In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
Remark:
- After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address>
- Select the item and press <OK> on the RC.

After NVM replacement, reload MAC address via SAM menu.This ensures the correct MAC address to be available in CSM for future repair actions.
Way of working:
• After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address> .
• Select the item and press <OK> on the RC.
Notes:
• Only applicable to all related models that are “Smart TV level 0”enabled (only YouTube access). For models without internet connection feature, no action is needed.
• HDCP keys are located in the NVM.
New NVM EEPROMs are shipped with pre-loaded HDCP keys.

SSB Identification
SSB’s of this chassis are identified by a “715” code on the SSB.

715Axxxx-Nnn-MMM-OOOO
• 715 main category, Printed Wiring Board
• Axxxx sub category, sequential coding number
• Nnn Version code
• N Development number
• nn Production number
• MMM Mounting variation code
• OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement panel.

Cable position numbers
In this chassis, the cable position numbers can be defined via the rule that the number is always starting with an “E” followed by the connector number of the current sourcing board. The order is always seen from where the power initiates from. So from PSU to SSB, from SSB to IR/LED panel, from IR/LED panel to keyboard control panel. For example, a cable from the PSU connector CN902 to the SSB connector CN701, will have the position number ECN902.

Wiring details

Alignments and Adjustments

Usually, a color LCD-TV needs only slight touch-up adjustment upon installation.
Check the basic characteristics such as height, horizontal and vertical sync.
Use the specified test equipment or its equivalent.
Correct impedance matching is essential.
Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test result.
Connect the TV only to an AC power source with voltage and frequency as specified on the back cover nameplate.
Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts.
To protect against shock hazard, use an isolation transformer.
