Re: Panasonic Plasma TV LED blinking 12 times

FYI, a replacement P board was sent to me and my TV is now working again. Total cost of repair was $86 for the P board and a $50 testing charge on the A board that was originally thought to be the problem.

Thanks Badcaps forum!!

Re: Panasonic Plasma TV LED blinking 12 times

That's kind of what I was thinking. The P board I bought was from a different outfit and came with a 6 month warranty. I guess I'll either send it back for exchange or take the Moduslink (who has been very good to work with) route.

Re: Panasonic Plasma TV LED blinking 12 times

Well, I didn't get the same results as PaulF. My replacement P board arrived today and after installing it, I have 10 blinks rather than 12. Following that flow chart, I come to the end and it instructs to replace A board.

Just to confirm, that was my first diagnosis and had sent my A board to Moduslink for repair. They found no problem with it and said it ran for several hours in their test set. They want me to send both my original P and A boards together for testing side by side. It's about $160 each to repair. If both...

PaulF, I'm glad to hear you fixed your TV. (Sorry to hijack your thread earlier, but I was new to this forum and couldn't start my own).

I have different boards on my TC-P42S1 tv, but tried the same as you as suggested in the documentation I could find. I sent my A board in to be repaired and it was returned with a note that it passed all tests and to check other boards. I'm leaning now towards the P board.

All standby power readings are good on my TV and the A board does send a 3.2V "panel_main_on"...

TW2005,

You are correct that the part number is TXN/A1EFUUS and the board number is TNPH07861A. There is no suffix that I can tell. Pictures are attached of the board numbers I find and the panel info....

Re: Panasonic Plasma TV LED blinking 12 times

Hello Badcaps Forum. I found this board looking for an answer to my "12 Blink" issue on a Panasonic TC-P42S1 plasma. I've read about everything on here and other websites trying to determine if I can fix it for about $200 or so. If not, I'll probably buy new.

The TV is about 3-4 years old and has had no issues until one day on power down, we heard an additional click after it shut off and immediately the SOS light started flashing.

Here's what I've checked:
- unplugged SC board, 12 blinks...
