Re: Philips 43PUT6162712 backlight on,tv locked no standby led
The EEPROM is only 16 KByte, or 128 Kbit.
It mainly contains calibration settings that are specific to your panel.
You say that "all tensions seem correct", by this I guess you meant "all voltages" before Google Translate decided to be helpful.
The service manual is downloadable from this page:
https://www.electronica-pt.com/esque...ileinfo/66357/
At one point the service manual says:
"In this manual, no detailed information is available because of design protection issues."
But they have been pretty good at listing all the voltages and their expected values, and have provided annotated photos of the PCBs where measurement points for various voltage rails are pointed out.
Have you followed the service manual in confirming all the documented power rails?
If the TV goes into protection immediately, it may turn off some power rails, and the service manual doesn't mention any override for that with for example a hardware SDM.
But at least +5V-STB should be present in all states.
If you plug in power to the TV and leave it for 5 minutes, does it eventually start blinking any error codes on the power-LED?
It can take a while for the TV to enter this protection state, if it is silently trying to reboot itself several times before giving up and eventually falling into the protection state.
If you get no blinking codes at all, then maybe the standby-processor is not even running, and I guess that could be caused by missing elementary power rails.
Or the main processor chip may have heatwarped itself off the pads that are connected to the integrated standby-processor.
