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.

PHILIPS 40PFL6606-D - LCD TV - SSB REPLACEMENT - ADJUSTMENTS - SET STARTS UP IN FACTORY MODE

40PFL6606-D - PHILIPS LCD TV - SSB REPLACEMENT - Adjustments - SET STARTS UP IN FACTORY MODE


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).
