Re: A guide to fixing/troubleshooting some common plasma TV problems

Definitely. There's a group in Texas that seems to have it in stock so I'll check all connections on the current board tonight and if I don't have any luck, I'll order another board and give it one more try.

It feels so close, I just can't give up yet!

Thanks,

Re: A guide to fixing/troubleshooting some common plasma TV problems

I was pretty careful about seating each of the ribbons, but I certainly will double-check that. In my research, I did see that these can be a bit finicky, so that's worth another look.

I think you may be right about the SU board, but I'm not sure if I'll be able to find another one. I'll start looking again and see if I can locate another one.

Thanks much for the help,
Voy

Hi Tom-

Any thoughts on what else to try? I'm afraid it's time to bring this set to the tech recycling drop-off, but want to check if there's any other possibilities.

Thanks,
Voy

No, everything looked good for the brief time that the display came up.

Re: A guide to fixing/troubleshooting some common plasma TV problems

Hi Tom-

I'm afraid my bold experiment in fixing my Panasonic plasma may be over, but I want to run this by you to see if there are any other options.

I have a Panasonic TH50PX75U that started giving the 7 blinking lights error a few weeks ago. I did some research and was able to diagnose the problem to the upper scan board (TNPA4188). When I unplugged this board, the bottom half of the screen displayed correctly. When the board is plugged back it, it goes back to the 7 blinks error....
