Re: Panasonic TC-P54G25 8 blinks

I followed the troubleshooting guide for 8 blinks. When I checked the connectors from the SS card to the panel one of the ribbon cable connectors seemed loose so re-seated all three (one was on the small lower SS2 board). I also checked continuity between pins 1 and 2 on the 2 connectors from SS to the panel they were ok (one was 1 ohm the other 2 ohms). Checked between pins 6 and 7 on connector between SS and SS2 and again 2 ohms (seems ok). I plugged everything up and the TV ran fine for 30 minutes or so they shut off and now shows 10 blinks. ...

Thank you very much for this information. I will perform the steps and post the results this evening when I get home.

Re: Panasonic TC-P54G25 8 blinks

Starting from the rear right side of the TV the images are: both SS and A board, just right SS board, just A board, power supply, left ss board and the entire left side.

I think I have the board names (ss, a...) right but I'm not sure.

The right ss board has the part number TNPA5082
The A Board (has all the video connectors) part number TNPH0834
The left side ss board part number TNPA5081

If you need more detailed pictures of any boards let me know

Thanks for your help...

Hello,

My Panasonic TC-P54G25 manufactured Nov 2010 has worked great for several years. A few weeks ago it would turn itself off and the front power LED would blink 8 times. I would unplug/plug the system and it would come on and run for several weeks then shut off again. Now the set comes on and runs for 5 minutes before shutting off with 8 blinks. I researched the issue and most point to the SS board (my set uses the TNPA5082 board on the right side and the TNPA5081 board on the left side looking at the back of the set). The first step seems to be to make sure the flex cables...
