Panasonic plasma Television VIERA TC-P50G10 During operation, the screen went black and the power light blinks 7 times. I tried unplugging everything, holding the power button for 60 seconds and replugging in power cord and holding for 20 seconds. I also tried holding power button and the volume button at the same time. I took the back off and do not see anything obvious like a leaking capacitor. Looked over the SC board especially well. Checked for some open circuits where I could on the SC board. No luck. Any advice would be appreciated.
@doninbush the 7-blink error code is for the SC floating voltage area and the boards to check are the SU SD and SC boards. You can check by unplugging the SU board and see if you still get 7 blinks. If so, disconnect the SD board and check for the 7 blinks. If so, disconnect the SC board and see if you now get 6 blinks or any other change. That would be indicative of a bad SC board. To absolutely test it place a jumper at SC50 on the SC board and the buffers (SU SD)disconnected. If it then powers up with the LED still flashing your SC board has failed. Make sure you do not keep it powered on with the jumper for longer than 30 sec. It might also help if you post some images of your boards with your question. It would allow us to see what you see. Use this guide Adding images to an existing question for that. Slightly different model but same idea, check this video
