Hello everyone, I have a panasonic tc-p50g20. There was some flash of electricity and after this event the TV began to flash 10 shots. However, when I press the power button after the relay clique when reconnecting the TV, it flashes 4 shots. So I followed the troubleshooting guide for the 4 blinks. The last test gives 3.3 volts on pin 9 of connector P7. Subsequently, he tells me to change the P-Board.I would like some help in targeting the problem component on the P-Board. By the way, The VSUS and P15 is dead. By cons, I did the different test the Short for VSUS VDA and P15. No results below 1kohm.Thank you for your help.Jeff

Unplug the tv and wait 10 minutes. Unplug the connector going from the power supply to the SC board. Plug tv back in, turn on and see if you get 7 blinks. If you do, the SC board is bad. They are very hard to find. You must also check the upper and lower buffer boards.

I'm not at home right now, but I did all the short circuit tests that were negative. I also did the test attached and it came to the conclusion that it was the Power Supply Board since I had 3 volts on the pin 9 of P7 connector l. If it helps to draw a conclusion. I also ordered a rebuild kit for the P Board from Shop Jimmy. Thank you for your help again! For Now I change the IC201(resonance control) & IC202(Comparator) both thing hard to test. So here I am right now.

I change lot of part like I said on the P board always the same 4 Blinks.
Should I do some short test on the SC board to be sure ?
Thank you for your help.

It is DEFINITELY a bad sc board. Do some testing on the IBGTs and you will find some shorted ones. There are repair kits that have up to 100 or so components to change. If you miss anything, that board goes up in smoke again. Way too hard for me to attempt a repair on that sc board.
