Panasonic th-42pe7 12 blinks

[Malachi]

I have a th-42pe7 with 12 blinking sound SOS that I got for a 12 pack. A main board is $100.
Not worth it. And it's a 720p.
Could someone with limited soldering skills repair the mainboard?

Have you eliminated shorted speaker wires or damaged speakers first?

I completely disconnected the speakers from the board. That didn't help.

Have you got the manual, had a look at the circuit yet? Audio IC is pretty big . Could be a challenge but as you say these older Tvs are not getting much value.

I'm in a pickle myself, got a 50S10 and a 50G15. Both good TVs and great picture, did component level repair on one but now I've got it running the speakers are shagged in both. $100 a pair from the US, kinda stuffed at that price so I'm going to either flog them off as is or break down the spares.

So I guess cahse the newer stuff but they ended in 2013/14 the Panny Plasmas.

Does this help?

Re: Panasonic th-42pe7 12 blinks

I got a supposedly working mainboard in today. I've replaced the SC board and SS board, they were cheap, $15.
The green LEDs on the boards turn on but I still get 12 blinks.
I'm left with the psu, control board and Lower buffers.
Any ideas?

Could it be the D-board, the logic board?

Ohh my days I love the diagnoses here, so in depth and accurate. Were willing to help just please stop throwing parts at it Malachi save yourself money and learn along the way !

Maybe try running the test patterns I know you can override some errors on Panasonic's into test patterns.

Re: Panasonic th-42pe7 12 blinks

According to the service manual, if the SS and SC board LEDs light up its a bad D-board.
I know you guys tried to help me but for 2 and a half months no one had any I out on it.
I bought SC and SS board for a combined $15. I lost $15 to return the mainboard.

I don't want to keep pestering. If after a while there are no suggestion s I start throwing parts at it.
I don't want to piss people off by nagging.

I see just realised the thread dates, I dont mind and im sure others dont mind you boosting the post we can help just might not be first thing. Its a forum with alot of members so anyone could comment. Also does sound like a D board to me just resing the SM now.
