The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power receptacle, when servicing this chassis.
To prevent electric shock, do not remove cover. No user-serviceable parts inside.

It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver.

This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in close proximity to the receiver for long periods of time. To reduce any risks associated with this, observe the following precautions:

1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 30.5 KV, (at a instantaneous beam current of 1300)
2. Ensure that during normal operation the EHT does not exceed 25.0 KV +/- 1.5KV (at a beam current of 1100.) This level has been preset in the factory. Always check that this level has not been exceeded after carrying out any repair on the receiver.
3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause excessive x-ray radiation.

White Level

Set the brightness control, with no signal connected, so that the CRT cathode current is 600mA. The maximum correction applied to each cathode current to achieve a screen temperature of 8900 degrees K-20 MPCD should not exceed 15% of its original value.

HI-POT TEST

1. Hi-Pot Test
CAUTION - All units that are disassembled as part of a repair MUST be Hi-Pot tested before being returned to the customer. This test applies a high voltage to the AC line cord and measures the current leakage to the chassis and/or other metal parts on the outside of the unit to check for potential shock hazards.
If the unit fails Hi-Pot test, it must be rerturned to the technician for troubleshooting and repair of the problem, after which it must be Hi-Pot tested again to ensure that it now passes the test.
Hi-Pot Tester Settings:
Type of product: 120 VAC 2-wire Class II
Test Voltage: 1500 VAC
Trip Current Limits: 2mA min, 6mA max
Ramp: 1 sec
Dwell: 2 sec
Type of product: 220 VAC 2-wire Class II
Test Voltage: 2500 VAC
Trip Current Limits: 2mA min, 6mA max
Ramp: 1 sec
Dwell: 2 sec

2. Hi-Pot Test Procedure
2.1 Connect the positive side (hot) of the HiPot tester to both terminals of the AC mains input.
2.2 Connect the return of the Hi-Pot tester to all connections on the 3.5mm audio jack, ground shell on either USB connector and all points on the Ethernet connector.
2.3 Connect the continuity check terminal of the Hi-Pot tester to the shell of the USB. (all grounds are connected to the same point internal to the product, so only a single connection point is required). This test must be performed only after the system has been completely assembled.
Failure of this test indicates a faulty transformer, defective or incorrectly dressed primary wiring, improperly attached leads, surface contamination of either the power supply board or the I/O connector board, or incorrectly adjusted trip point on tester.

The LCD Panel Assembly includes the LCD Panel, TCON Board, and LED Back-light system.
The LCD Panel contains the actual liquid crystals, color filters, and polarizers. The liquid crystals are manipulated by the applied voltage to pass a specific amount of light - from the back-light - depending on the level of voltage applied.

The TCON performs all the control, timing, charge, and discharge functions driving the operation of the LCD Panel.

TCON Board (Internal - not available as a replacement part.)

The inverter receives the unregulated 24V from the Power Supply Board and generates the required high voltage AC to power the backlight lamps. A control line to turn on the inverter (backlights on) is used in conjunction with a dimmer control to vary the light level of the CCFL lamps.

SELF DIAGNOSIS FUNCTION

Critical voltages and circuit operations are monitored by the CPU on the Main Board. If an error is detected the Self Diagnosis function in the TV will force the TV to shut down by the CPU. The monitored circuit in which the fault occurred will automatically cause the CPU to blink the Standby LED in groups of repeating sequences. The number of times the Standby LED blinks indicates the possible cause of the problem.
Not all of the available protect codes are used in every model. For example, models that don’t have the local dimming feature do not use the 4X blink error as this circuit is found in models that are back-lit with fluorescent lamps. The information in this section provides guidance in locating the possible component causing the shutdown.

STANDBY LED BLINK COUNT

UPDATING THE SOFTWARE

The Self Diagnosis function is designed to provide information regarding the problem with the TV, however, there are several issues that may be resolved by updating the TV software to the latest version. Always check for any issues that are software related. Most symptoms that are correctable by software updates involve communications issues with other devices or minor glitches in the operation of a specific function. Below is a list of some of the symptoms that may be corrected with a software update:

Fluctuations in picture brightness

Intermittent picture freezing or noise
Problems with certain inputs (especially HDMI)
Intermittent or distorted audio
Erratic remote control operation
TV turns on and off by itself
Loss of color
Internet connectivity
Certain features not working correctly (photo or video file viewing)

VIEWING THE SELF CHECK DIAGNOSIS HISTORY

When an error is detected, the Self Check screen records the error that occurred. This is helpful in confirming past occurrences of an error, and for determining if an error is intermittent when the customer is not sure what is causing the television to shut down. If the screen displays a “0”, no error has occurred.
You must got into Service Mode to access the Self Check menu.
1. TV must be in Standby mode. (Power On).
2. Press the following buttons on the Remote Commander within a second of each other:

To access the Self diagnosis history page, press the DN button until Self diagnosis history is highlighted, and then press (+)

To exit the Self Check, press MENU

Review the information to determine the most likely source of the error.

Standby LED blinking codes details

2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The usual cause is a failure of the main switching supply. In some instances, excessive loading on the secondary supply lines can cause the switching regulator to stop, or fail again, if a replacement board is installed.
3X Blink- DC Regulator/Audio Error
The REG 5V and D3.3V source originating on the Main Board is monitored for low-voltage conditions by the CPU. A failure causing a 3X shutdown requires replacing the Main Board.
4X Blink – Balancer Error NOT USED IN THIS MODEL SERIES
The 4X error code is only used on models incorporating local dimming LED backlighting. If a failure occurs on the LD board or one of the LED’s fails in the panel the TV will shut down and display this diagnostic code. Models using conventional non-local dimming LED backlighting do not utilize this error code.
5X Blink - TCON Error/Panel Error
The 5X blink protection mode indicates a communications error with the timing control circuits (TCON Board) has occurred. If the TCON Board is available for replacement, replace it, if not, replace the LCD Panel Assembly. In rare cases a loose or defective LVDS cable could also be the cause.
6X Blink - Backlight Converter System Failure
If the inverter circuits fails to generate high voltage or one or more of the backlight lamps fails to light, the television will shut down and display this diagnostics error. Observing for the presence of backlighting is crucial in determining which component is likely at fault.
If the backlights turn on before the 6X shutdown occurs, it is safe to assume that the inverter circuits are functioning and one of the lamps failed to ignite. Replacing the LCD Panel assembly is necessary. If the backlights never turn on before the 6X shutdown, the Inverter MT Board has failed. If this board is available for replacement, replace it, if not, replace the LCD Panel Assembly.

7X Blink - Temperature Failure
A digital thermometer IC located on the Main Board provides a temperature reading of the chassis and LCD panel. If the temperature exceeds a predetermined point the TV will shut down. If this problem occurs immediately at turn-on, the temperature sensing IC has failed and replacing the main board is required. If this occurs after the TV has been running for a while, check for ventilation issues that could cause the TV to run hotter than normal.

Disassembly

Gently place LCD TV face down onto a soft cloth and remove 3 screws from Table-Top Stand.

Remove screws from Rear Cover.

15 from KDL-32BX355 Only
17 from KDL-40BX455 Only
19 from KDL-46BX455 Only.

Do not damage the Power Board Connector and AC Power Cord when removing the Rear Cover.

Carefully lift Rear Cover from bottom side and push forward to release top hooks.

Hold Power Supply Cord while lifting up Rear Cover, then pass Power Supply Cord through Rear Cover opening.

Updates and adjustments

The models discussed here utilize a “generic” type of Main Board, therefore a software update must be performed and certain service adjustment settings must be changed or confirmed whenever the Main Board, LCD Panel, or TCON Board is replaced.
There are 2 reasons for updating the software on the TVs.
Software updates for customers
These updates are for enhancements or improvements that have been made to the software after the TV was released.
Software update for servicers
These updates are specifically for servicers to use during a service call.

The subject of software updates is very important. The televisions of today have advanced to the point where they are not simply a television anymore.
They are evolving into devices that are designed to integrate with numerous other devices found in the home. Some examples are: portable audio and video devices, still cameras, home computer networks and accessing the internet to name a few. Communications with these varying devices requires that the television be
compatible with varying communications protocols. Although standards are detailed for each of these protocols, the real world dictates that occasional errors may occur that could prevent devices from operating or communicating properly.
Keeping the software in the television up-to-date is a procedure that is normally handled by the owner of the television. Most customers who own computers and other digital devices are familiar with and are accustomed to updating the software in their products. If a customer contacts the Sony Customer Support Center and it is deemed to be correctable with a software update, the issue is handled at the customer level.

Software updates can be performed by:

Customer Manual Downloads: Software updates can be performed by the customer by placing it on a USB device to be loaded onto the TV. The instructions for downloading the software file vary from chassis to chassis and sometimes from model to model.
The customer is provided with the instructions to properly format the USB device, unzip the file, and the procedures for loading the software into the television.
Network Downloads: Internet software updates are becoming more prevalent as more and more models incorporate home network capabilities. This method is the most practical since the television will check for the latest version of software. The models with this type of chassis provide the customer with a choice of
turning the automatic software update feature on or off. If set to on, the television will lookup software information while the unit is in standby. If a newer version is available, it will be downloaded and installed without any input from the customer.
Built-in Tuner: OTA or cable sources having the proper station that is transmitting software update data packets. Although the ability to transmit software update is possible in this way, it is the least common and is reserved for particular situations where a critical update is “forced”, thereby updating the TV without any input from the customer.

SOFTWARE UPDATES FOR SERVICERS

Replacement Main Boards are now stocked with basic software. Once the replacement board is installed in the TV, the most current software needs to be installed using a USB device containing the necessary software.
This new method of supplying Main Boards significantly reduces the complexity of replacing the Main Boards. Information about the LCD panel is stored on the TCON circuits. This information is automatically loaded onto the Main Board when the TV is powered up. With the correct software version the Main Board and/or the TCON can be replaced more efficiently.

SOFTWARE UPDATE RESPONSIBILITY

Software updates are designed to be performed by the customer. Warranty repairs in which the issue can be resolved by a software update are not reimbursable. Most issues involving software updates are handled by the customer service center and should not be directed to an authorized service center. It is the responsibility of the servicer to prevent service calls for issues that involve software updates. Exceptions to this are certain cases whereby the customer is unable or unwilling to perform the task. In this situation, the servicer will be notified and receive the proper authorization for reimbursement.
It is the servicer’s responsibility, however, to make certain that any TV requiring a legitimate service is running the latest software version and to install it if necessary.

CHECKING THE SOFTWARE VERSION
The easiest way to check the version of software that is currently on the TV is to access the Contact Sony screen by using the customer menu.

EXAMPLES OF SOFTWARE CORRECTABLE SYMPTOMS
Always check for any known and/or listed issues that are software related. Most symptoms that are correctable by software updates involve communications issues with other devices or minor glitches in the operation of a specific function. Below is a list of some of the symptoms that may be corrected with a software update:
● Fluctuations in picture brightness
● Intermittent picture freezing or noise
● Problems with certain inputs (especially HDMI)
● Intermittent or distorted audio
● Erratic remote control operation
● Unit turns on and off by itself
● Loss of color
● Internet connectivity
● Certain features not working correctly (photo or video file viewing)

Dolby® Digital or DTS® (or Other Digital Surround Mode) Connection Use this installation method for dolby digital, dts or other digital surround processors:

Use the line-level input jack marked SUB (6) for the low-frequency effects channel.
Connect this jack to the subwoofer output or LFE output on your receiver or amplifier.
Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

Make sure you’ve configured your surround sound processor for “Subwoofer On.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

Dolby Pro Logic® (Non-Digital) – Line Level

Use this installation method for dolby pro logic applications (not dolby digital, dts or other digital processing), where the receiver/processor is equipped with a subwoofer output, or a volume controlled preamp (line-) level output:
Use the supplied RCA-type interconnect cable to connect the line-level subwoofer output on your receiver or amplifier to either the left or right Line-Level Full-Range Input (7) on the SUB-TS11 subwoofer.
Use both the left and right inputs on the subwoofer if your receiver or processor has both left and right line-level outputs. In that case, you will need to supply a second interconnect cable.
If your receiver is equipped with line-level outputs but does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver’s preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the SUB-TS11.
IMPORTANT: Do not use the SUB Input (6) on the subwoofer with Dolby Pro Logic processors.
If your receiver/processor has a built-in lowpass-crossover filter for the subwoofer output, you may use the SUB Input (6) to bypass the subwoofer’s internal crossover.
Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.
Make sure that you have configured your surround sound processor for “Subwoofer On.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

Dolby Pro Logic (Non-Digital) – Speaker Level
Use this installation method for dolby pro logic applications (not dolby digital, dts or other digital processing), where the receiver/processor does not have a subwoofer output, or a volumecontrolled preamp (line-) level output:
Connect your receiver or amplifier’s front left and right speaker terminals to the left and right Speaker-Level Input (9) terminals on the SUB-TS11 subwoofer that are marked “High Level In.” Connect the left and right Speaker-Level Output (8) terminals on the SUB-TS11 subwoofer that are marked “High Level Out” to the corresponding terminals on the back of your front left and right speakers.

How to repair the parking sensor module whose plate has the following RoHS code PR-B62-04 192507

Installed this parking sensor on my Hilux (with metal bumper) on dealer and within a short time ago, the LCD display had the following errors when driving in reverse: "E3" and "E4". These two sensors 3 and 4 stopped working.

Original Module

Problematic signal transformer

Opened the module and did some tests and found that the signal transformers (variable inductors with two windings) of sensors 3 and 4 were in problem, as they did not present continuity between (pins 4-6). I searched the internet for this signal transformer marked "UP 04" and found nothing.

There is no information or any other details about this device fount by internet.

Inductor Pinout

Decided to look for a similar module. The module has a label “P / N: PR-2332". Searched the internet and found some original modules from other GM vehicles with the same "P / N: 2332" and with the same pin out. Purchased one of these used GM modules and removed two signal transformers and replaced the ones that had a problem with my original module. The purchased module cannot be used here because of the firmware recorded on the microcontrollers are different.

GM module

On the GM module, the LCD display shows nothing and is only beeping according to the distance from the obstacle.

So, leave the tip here for anyone who has problems with the vehicle's parking module.

Power Output, RMS

: 60 watts per channel into 4 Ohms, 20 ~ 20,000Hz

: 90 watts per channel into 2 Ohms, 20 ~ 20,000Hz

: 180 watts bridged mono into 4 Ohms, 20 ~ 20,000Hz

Alignment procedure: Idling current adjustment

Conditions:

-Connect the DC voltmeter between TPl and TP2 and between TP3 and TP4.

-Connect a 13. 8V power supply to the 12V Battery

Power In terminal.

-After the power on, wait for 5 minutes before measuring to be sure of the most stable operation.

Inspection:

-Confirm that the idling current is 50mA :t 20mA (voltage: 33mV:t 13mV).

If the current measured does not fall within the range specified , adjust it with the procedure below.

Adjustment

Note: When replacing or disconnecting a resistor, disconnect the power supply first.

After the adjustment is complete, let the unit settle down for 10 minutes, than double-check that the idling current is set properly.

Wiring diagram

Protection circuit

If the temperature inside the CA260 rises above 80 the protection circuit comes into operation , decreasing output. At this time the protect indicator blinks. If the temperature comes back below 80 C by natural cooling, output returns as it was.

If the temperature rises above 100 , the power supply circuit is shut off . Not only does the output stop, but also the protect indicator goes out. If this happens, it is possible that the CA260 is broken. However, even in this state, it cannot be always said that it is broken because the unit may operate when the temperature comes back below 80 C by natural cooling.

Repair Flow Chart

It is critical that the DC Voltage adjustments be checked when:

1) SMPS, Y-SUS or Z-SUS board is replaced.

2) Panel is replaced, Check Va/Vs since the SMPS does not come with new panel.

3) A Picture issue is encountered.

4) As a general rule of thumb whenever the back is removed.

DC VOLTAGE ADJUSTMENTS

1) POWER SUPPLY: VS, VA (Always do first)

2) Y-SUS: Adjust –Vy, VSC.

3) Z-SUS: Adjust Z-Bias (VZB).

WAVEFORM ADJUSTMENTS

Y-SUS: Set-Up, Set-Down.

The Waveform adjustment is only necessary.

1) When the Y-SUS board is replaced

2) When a “Mal-Discharge” problem is encountered.

3) When an abnormal picture issues is Encountered.

DC Voltages developed on the SMPS: Adjustments VA and VS.

Always refer to the Voltage Sticker located on the back of the panel, in the upper Left Hand side for the correct voltage levels for the VA, VS, - VY, VSC, and Z Bias as these voltages will vary from Panel to Panel even in the same size category.

Set-Up and Ve are just for Label location identification and are not adjusted in this panel.

SMPS p/n: EAY60968701

Check the silk screen label on the top canter of the Power Supply board to identify the correct part number. (It may vary in your specific model number).

The Switch Mode Power Supply Board Outputs to the:

AC Voltage is supplied to the SMPS Board at Connector SC101 from the AC Input assembly, routed to the Standby 5V supply. The STBY5V (standby) is B+ for the Controller chip on the back of the board (IC701) on the SMPS and output at P813 pins 13 and 14 then sent to the Main board for Microprocessor (IC1) operation (STBY 3.46V RUN 5.14V).

When the Microprocessor (IC1) on the Main Board receives a “POWER ON“ Command from either the Power button or the Remote IR Signal, it outputs a high (2.43V) called RL_ON at Pin 15 of P813. This command causes the Relay Circuit to close both Relays RL101 and RL103 routing AC to the Bridge Rectifier D101 which then routes the primary voltage to the PFC circuit (Power Factor Controller) 388V which can be read measuring voltage at Fuses F302 and F801 from “Hot” Ground. AC Detection (AC Det) is generated on the SMPS, by rectifying a small sample of the A/C Line and routed to the Controller (IC701) where it outputs at P813 pin 16 (4.44V) and sent to P301 to the Main Board where it is sensed and monitored by the Main Microprocessor (IC1). If AC Det is missing the set will come on, but shut off in 10 seconds.

When RL_ON arrives, the run voltage +5V source becomes active and is sent to the Main Board via P813 (5.17V at pin 5, 6 and 7). The (Error Det) from the SMPS Board to the Main Board can be measured at pin 8 of P813 (2.85V STBY and 4.90V RUN), but it is not used. The RL-ON command also turns on the 17V (Audio B+) which is also sent to the Main Board. The 17V Audio supply outputs to the Main board at P813 pins 1 and 2 and used for Audio processing and amplification.

The next step is for the Microprocessor IC1 on the Main Board to output a high (3.29V) on M_ON Line to the SMPS at P813 Pin 17 which is sensed by the Controller IC701, turning on the M5V line and outputs at P812 pins 9 and 10 to the Y-SUS board.

The Controller (IC701) also uses the M_ON line to turn on the VA and the VS supplies. (Note there is no VS On Command in this set). VS is output at P812 to the Y-SUS board P210. (VA pins 6 and 7 and VS pins 1 and 2).

Note: The Va is fused on the Y-SUS then routed out P203 to the X-Board Left. VS is also routed out of the Y-SUS P211 pins 4 and 5 to the Z-SUS.

P2.

AUTO GND Pin 18 of P813:

This pin is grounded on the Main board. When it is grounded, the Controller (IC701) works in the normal mode, meaning it turns on the power supply via commands sent from the Main board. When AUTO GND is floated (opened), it pulls up and places the Controller (IC701) into the Auto mode. In this state, the Controller turns on the power supply in stages automatically. A load is necessary to perform a good test of the SMPS if the Main board is suspect.

SMPS STATIC TEST UNDER LOAD

Using two 100 Watt light bulbs, attach one end to Vs and the other end to ground. Apply AC to SC101. If the light bulbs turn on and VS is the correct voltage, allow the SMPS to run for several minutes to be sure it will operate under load. If this test is successful and all other voltages are generated, you can be fairly assured the power supply is OK.

Note: To be 100% sure, you would need to read the current handling capabilities of each power supply listed on the silk screen on the SMPS and place each supply voltage under the appropriate load.

Note: To turn on the Power Supply.

1) With Main Board connected, press power.

2) Without Main Board connected SMPS will turn on automatically.

Any time AC is applied to the SMPS, STBY 5V will be 3.46V and will be 5.14V when the set turns on.

AC DET WILL NOT be present until set comes on.

If AC Det is missing, the TV will come on and shut off in 10 Seconds.

With P813 disconnected from the Main board (P301) attach two 100 Watt light bulbs, attach one end to Vs and the other end to ground.

Apply AC to SC101. If the light bulbs turn on and VS is the correct voltage, allow the SMPS to run for several minutes to be sure it will operate under load. If this test is successful and all other voltages are generated, you can be fairly assured the power supply is OK.

Note: To be 100% sure, you would need to read the current handling capabilities of each power supply listed on the silk screen on the SMPS and place each supply voltage under the appropriate load. Then follow the instructions below to completely test turn on sequence.

Note: Placing the two 100 Watt light bulbs from Vs to Ground will assure the power supply will regulate with a load and no other Abnormal conditions may result.

When the supply is operational in its normal state the Auto Ground line at Pin 18 of P813 is held at ground by the Main Board.

This Power Supply can be powered on sequentially to test the Controller Chip IC701 operational capabilities and for troubleshooting purposes.

Disconnect P301 from the Main board and use the holes in that end of the connector to insert the jumper and resistors.

Warning: Remove AC before adding or removing any plug or resistor.

Note: Leave previous installed 100Ω resistor in place when adding the next resistor.

(A) Ground the Auto Gnd Line (Pin 18) will allow the supply to be powered up one section at a time.

(B) Add a 100Ω ¼ watt resistor from 5V Standby to RL_ON and the AC Det, 17V and 5V Lines on P813 will become active.

P812 (VS pins 1 and 2) (VA pins 6 and 7) and (M5V pins 9 and 10)

Connector “SMPS" to “Main" P301.

Note: The 17V, 5V, AC_Det and Error Det turn on when the RL_On command arrives.

Note: The M5V, Va and Vs turn on when the M_On (Monitor On) command arrives.

Note: The Error Det line is not used in this model.

Note: If the AC Det line is missing, the TV will shut off after 10 seconds of operation.

Note: Pin 18 is grounded on the Main board. If this line is floated, the SMPS turns on Automatically when AC is applied.
