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.

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”.

How to upgrade
* Copy the “upgrade.bin” file to the root of the USB stick.
* Power “off” the TV and remove all memory devices.
* Insert the USB stick that contains the downloaded software upgrade.
* Switch “on” the TV, and activate the Main menu with the “Menu/House” key on the remote control.
* In the Main menu, go to the “Software update” item.
* Press “OK” key to go to the submenu.
* Select “Local updates” in the submenu and press the “OK” key to enter the Software Update application.
* You will be prompted to cancel or to proceed with the software updating.
* 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.
* Upgrading will now begins 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

{Never attempt to do a software update procedure; unless you're confident that you can do it properly.  It is advised to seek assistance of any experienced service technician.  Improper version of software upgrade might even make the set not respond  to any external commands; means it has gone for ever.}
