REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

Software Upgrading
It is possible for the user to upgrade the main software via the USB port. A description on how to upgrade the main software can be found in the DFU and below.
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.
How to upgrade
1. 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 submenu.
7. Select “Local updates” in the submenu 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. See ComPair for further instructions.
HDMI-side EDID NVM
Upgrade VGA EDID NVM
To upgrade the VGA EDID NVM, pin 7 of the EDID NVM [2] has to be short circuited to ground. See ComPair for further instructions
Main SW upgrade flowchart.
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.
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, and what brand and type of display is used.
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 *).
Tips:
• 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 initialized first (loaded with default values). This initializing can take up to 20 seconds.
Location of Display Option Code sticker
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).
Power supply
 All power supplies used in this chassis are a “black box” for Service. When defective, a new board must be ordered and the defective one must be returned, unless the main fuse of the board is broken. Always replace a defective fuse with one with the correct specifications! This part is available in the regular market.
The only type of power supply used in this platform is the Integrated Power Board (IPB) - incl. LCD backlight inverters.
It should be noted that for different display manufacturers, different PSUs can be used. When ordering a new PSU, always check which LCD panel is used in the set, and order the correct PSU
Video and Audio Processing - MT822x
The MediaTek MT822x is an ultra high integrated single chip for flat panel TV. It supports multimedia video/audio input and output format up to full HDTV.  It includes an advanced 3D comb filter/TV decoder to retrieve the best image from popular composite signals and embedded HDTV/VGA decoders for high bandwidth input signals.  The new 4th generation advanced motion adaptive and motion estimation de-interlacer converts accordingly the interlaced video into a progressive one with overlay of a 2D graphic processor.  Independent two flexible scalers provide wide adoption to various LCD panels for two different video sources at the same time.  The on-chip audio processor decodes the analogue signals from the tuner with lip sync control, delivering high quality postprocessed sound effects to the audio amplifier stage.  An on-chip microprocessor reduces the system BOM and shortens the schedule of UI design by high level C
