TEST MODE
The test mode allows you to diagnosis problems and make adjustments
using the remote commander and TV monitor. The instructions and results are given on the TV screen (OSD).
Test Mode Access
1. Plug in the DVD player,
2. Select DVD on the remote,
3. Aim the remote at the DVD player; and
4. Press the TITLE, CLEAR and POWER buttons one after another.  The red standby light changes to green and the blue Dolby Digital light will come on. The display will momentarily flash DIAG START as IC202 retrieves the program from the flash ROM IC205.
Exit
To leave the test mode, turn the power off.
Tests
The initial test mode menu shows seven options. Selecting a number enters that option level. You can navigate through each menu of that level using the remote’s PREV or NEXT keys. The RETURN key brings you to the previous level.
Syscon Diagnosis
This is a communications test between IC202 and IC on the parallel bus and is similar to the quicker checks that occur during power ON. If the unit powers on, it will usually pass this check.  Writing information in and reading the same information checks most ICs.  When the two match, the IC is deemed good. This testing occurs when the TV screen changes to a blue background. The IC is good if the original menu reappears.  In this check, the remainder of the video IC401 is tested by producing a video patterns to confirm operation. The audio IC501 is instructed to produce individual audio tones to each channel.
In checking the A/V Decoder (CDX1930 IC401), the OSD words “CHG_COLCON” mean this part of the IC is OK.
1. Drive Auto Adjustment
Automatically plays the disc and reloads new data into EEProm IC201.  This is used when memory IC201 or the optical assembly is replaced.  Test discs are required for these adjustments. The Super Audio CD (SACD) procedure is in this generic test program, but this DVD player cannot play SACDs.
2. Drive Manual Adjustment

Servo adjustments stored in EEProm IC201 can be altered manually. This operation is useful if you want to determine if the player can identify the disc type as the first step in playing the disc.
Within the Manual Adjustment is a Servo Control subsection that permits you to turn on each servo separately for observation. You can also play the disc and observe an eye pattern when all servos are on (sled does not come on in PB).
3. Mechanical Aging
This mode cycles the tray in, and then momentary plays the disc for identification. The number of cycles and the disc type found is displayed on
the TV screen.
4. Emergency History
This is the most valuable diagnostic information in the test mode. The last failure is recorded in EEProm IC201 and displayed on the TV. Ten codes may all pertain to one failure that affects various parts of the DVD circuitry that is monitored.

RESISTORS Remove and Replace with new part
CLICK ON THE PICTURES TO MAGNIFY 
Symptom: Unit intermittently powers off two seconds after powering ON.
Resolder IC206 and change parts on the MB and front panel Fl boards depending upon the serial number of the unit to insure a reliable power ON reset of key ICs. If your model falls outside of the serial numbers listed below or if the problem persists after the changes, perform the countermeasure in step 3. You must perform all the parts of the step.
Step 1
• On the MB board, locate Flash ROM IC206.
• Resolder the row of pins 23-44 at the bottom of the board.
• Inspect for bridges before powering the unit.
Step 2
Changes must be made to both the MB and FL boards: MB Board On the back of the MB board replace the following resistors:
• R212 from 220 ohms to 0 ohms (1-216-864-11)
• R226 remove 10k ohms resistor (open circuit)
• R755 from 5.6k to 10k ohms (1-216-833-11)
These last three changes increase the reset level from IC207 to the front panel micro IC201, and Servo DSP IC701. No parts have to be ordered to make these three changes.
FL Board:
Change two resistors on the back of the board:
• R251 - change from 1k to 120 ohms (1-216-027-91)
• R252 - change from 1k to 33 ohms (1-216-013-91)
These two resistors are located in different places depending upon the model.  For models DVP-S330, DVP-S530d and DVP-550d:
For models DVP-C650d and DVP-CX850d:
Step 3
On the MB board make the following changes:
• Remove R412 (open circuit)
• If the last two digits on the board are –11 to – 13 or –21 to –23, add a wire between one side of R412 and CN006/pin 1 (if the board ends with –14 or –24 do not add the wire).
Step 3 resets the A/V decoder IC401 sooner by taking the reset from an earlier location in the reset chain (directly from reset IC207/pin 4).

SOFTWARE UPGRADE
Attention
Software version numbers for 2011 sets are all defined below number 0.40.x.x. This might confuse servicers who store software versions for more than one set and/or platform on the same storage device (USB stick).
Always check the latest software version on the servicer website in relation to the correct CTN.
The set software and security keys are stored in a NANDFlash, which is connected to the PNX855xx.  It is possible for the userto upgrade the mainsoftware via the USB port. This allows replacement of a software image in a stand alone set, without the need of an E-JTAG debugger. A description on how to upgrade the main software can be found in the electronic User Manual.
Important: When the NAND-Flash must be replaced, a new SSB must be ordered, due to the presence of the security keys! (CI +, MAC address, ...).
Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software => see the eUM (electronic User Manual) for instructions.
3. Perform the alignments.
Reset of Repaired SSB).
4. Check in CSM if the CI + key, MAC address.. are valid.  For the correct order number of a new SSB, always refer to the Spare Parts list.
Main Software Upgrade.
The “UpgradeAll.upg” file is only used in the factory.
Automatic 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 “AUTORUN.UPG” (FUS part of the one-zip file: e.g. 3104 337 05661 _FUS _Q555X_ x.x.x.x_prod.zip). This can also be done by the consumers themselves, but they will have to get their software from the commercial Philips website or via the Software Update Assistant in the user menu (see eUM). The “autorun.upg” file must be placed in the root of the USB stick.
How to upgrade:
1. Copy “AUTORUN.UPG” to the root of the USB stick.
2. Insert USB stick in the set while the set is operational. The set will restart and the upgrading will start automatically. As soon as the programming is finished, a message is shown to remove the USB stick and restart the set.
Manual Software Upgrade
In case that the software upgrade application does not start automatically, it can also be started manually.
How to start the software upgrade application manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “OK” button on a Philips TV remote control or a Philips DVD RC-6 remote control (it is also possible to use a TV remote in “DVD” mode). Keep the “OK” button pressed while reconnecting the TV to the Mains/AC Power.
3. The software upgrade application will start.
Attention
In case the download application has been started manually, the “autorun.upg” will maybe not be recognized.
What to do in this case:
1. Create a directory “UPGRADES” on the USB stick.
2. Rename the “autorun.upg” to something else, e.g. to “software.upg”. Do not use long or complicated names, keep it simple. Make sure that “AUTORUN.UPG” is no longer present in the root of the USB stick.
3. Copy the renamed “upg” file into this directory.
4. Insert USB stick into the TV.
5. The renamed “upg” file will be visible and selectable in the upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (could be due to a corrupted boot sector) via the above described method, try activating the “back-up software upgrade application”.
How to start the “back-up software upgrade application” manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “CURSOR DOWN”-button on a Philips TV remote control while reconnecting the TV to the Mains/AC Power.
3. The back-up software upgrade application will start.
Stand-by Software Upgrade via USB
In this chassis it is possible to upgrade the Stand-by software via a USB stick. The method is similar to upgrading the main software via USB.
Use the following steps:
1. Create a directory “UPGRADES” on the USB stick.
2. Copy the Stand-by software (part of the one-zip file, e.g. StandbyFactory_88.0.0.0.upg) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see section “Manual Software Upgrade”.
5. Select the appropriate file and press the “OK” button to upgrade.

RESET OF REPAIRED SSB [Small Signal Board]
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 ComPair tool or 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. This action also ensures the correct functioning of the “Net TV” feature and access to the Net TV portals. The loading of the CTN and production code can also be done via ComPair (Model number programming).
After a SSB repair, the original channel map can be restored, provided that the original channel map was stored on a USB stick before repair was commenced and that basic functionality of the TV, needed for this procedure, was not hampered as a result of the defect. The procedure of “channel map cloning” is clearly described in the (electronic) user manual.
In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
SSB identification
Whenever ordering a new SSB, it should be noted that the correct ordering number (12nc) of a SSB is located on a sticker on the SSB. The format is <12nc SSB><serial number>. The ordering number of a “Service” SSB is the same as the ordering number of an initial “factory” SSB.
Instructions flowchart in case a SSB has to be exchanged.  Instruction note SSB replacement Q543.x, Q548.x, Q549.x, and Q55x.x
Before starting:
> prepare a USB memory stick with the latest software
> download the latest Main Software (Fus) from www.p4c.philips.com
> unzip this file
> create a folder ”upgrades” in the root of a USB stick (size > 50 MB) and save the autorun.upg file in this "upgrades" folder.
Note: it is possible to rename this file, e.g."Q54x_SW_version.upg"; this in case there are more than one "autorun.upg" files on the USB stick.
Due to a possible wrong display option code in the received Service SSB (NVM), it’s possible that no picture is displayed. Due to this the download application will not be shown either. This tree enables you to load the main software step-by-step via the UART logging on the PC (this for visual feedback).
