Re: 4 Blinks Panasonic TC-P50G20 Help to target the problem.
I followed this guide and the check points matched the reference in the guide. What could burn a card like this?
Is there a way to test the A board and P board by isolating them? I would like to know for sure....Leave a comment:

Re: 4 Blinks Panasonic TC-P50G20 Help to target the problem.
Doing the test for the A board chart indicated to disconnect the A1 connector and turn on the television. Which would indicate if the A board is good or not. The television turned on for 3 seconds and a big bang is heard. no more blinks display. However, the pin # 1 of the SC Board is short circuit. The board was brand new. grrrrr. Is this the pannel?Leave a comment:

I did some tests on the P board. I disconnected all the board wires and at pin # 1 of the P6 connector the resistance stabilized at 7.5 kohms. Is it considered a short circuit?Leave a comment:

After the procedure for shorted P15V. I have a resistance of 0.5kohms by connecting the SS board. disconnecting it, I go up to 3 Mohms. It looks like a defective SS board.
I hope it stops there.)

Re: 4 Blinks Panasonic TC-P50G20 Help to target the problem.
Hello everyone, so here I changed my SC board. but still the same problem. However, this time the power supply's power off click is slightly longer to come. I still have the same 10 blinks when the TV is plugged. When I turn on the TV, immediately after the first clicks, the TV turns on without any code, but after 10 seconds goes off with the code 10 blinks. Could you help me with that? Thank youLeave a comment:

Re: 4 Blinks Panasonic TC-P50G20 Help to target the problem.
Yeah it's true. Do I have to change firmware. Some persons said we have to change firmware when you change SC Board?
I don't remove IGBT but when I test capacitor in parallel with IGBT it's around 0.1 ohms so it shorted.
My board finish by AF so I need TNPA5081AF board right ?...Leave a comment:
