Both issues solved. Defective parts.

Re: Panasonic Plasma TC-P54S1, Two Problems

What would the compatibility problem be? TV is digital tuner and all stations are digital? It is only one channel that has no sound. All the others work perfectly. Would it be the tuner itself then?

The shrinking screen happened again. It is not 4:3, we were actually watching a program that transmits in that format. It shrunk to only the middle third and then back to the normal 4:3. And, it happened after a spark sound on the TV. What board controls those three sections is what we are trying to find out so we can repair i...

Panasonic Plasma TC-P54S1 - Two Problems:
Problem 1 - No Sound On Only One Channel.
We get our TV Channels 'Over The Air' and all the channels are Digital. We use the built-in TV Speakers, no external speakers. Never had a problem before.

Well, the new board arrived Friday and put it on yesterday. PERFECT Picture. Here is the first image after the TV was turned on.

So if anyone else ever has a problem like this, you know the solution.

Now here is a question? Anyone know who can repair the old board?

Thanks,

Re: Problem with Panasonic Viera TC-P54S1



I saw those two IC in that area but could not find anything saying what they were for. Before coming back into the forum, I went and froze the SD board again hoping for a sign... no such luck.

I did order an SD board just to be on the safe side since the SC board is definitely big bucks... But now, the TV has to be fixed because it has been driving me nuts since it started and I have to know what is causing it. Whichever board arrives first is the first one I am trying so, we sill see.
I uploaded the...

Re: Problem with Panasonic Viera TC-P54S1

Spent the day trying the freeze spray trick on the boards. Went top to bottom starting with the SD, then the SU and last the SC. The lines appeared on the SC board when the area around the TPSC1 was cooled down. As it warmed up again, they disappeared. Repeated it 3 times and each time, same result. No other areas on any of the boards caused the issue. Also took out all 3 boards and checked them front and back. They look brand spankin new and all solder points are solid... Put them all back in, turned on the TV and like clockwork... lines......

Re: Problem with Panasonic Viera TC-P54S1

Thanks for the replies and I am going to be careful with the freeze spray and use the cloth.
The TC-P54S1 is the same as the TC-54PS14 and TC-P54G10
I think the difference between the TC-P54G10 and the TC-P54G20 was that one was THX Certified and the other wasn't. But basically the same TV.

This is what is on the TV as seen from the back.

Hello. I am having a problem with our Panasonic Plasma that actually began this past Monday. Perfect on Sunday and this appeared when we turned on the TV Monday morning. When you first turn it on you see the screen divided into two halves, top and bottom, with vertical color lines filling the entire screen. This lasts a total of 4 minutes and then the screen looks perfect for as long as you leave the TV on. If you turn it off, say for an hour and turn it back on, it starts again and after 4 minutes, the image is again perfect. Here is a pic of what it looks like when first turned on. So basically,...

Re: New Members - please post your introductions here

Hi All... Found this board by accident while searching for causes for Plasma TV problems. I have been reading the threads for the past couple of days and decided it was time to become part of your community. Later on I will ask for help with the problems on our TV.
As for me, I am not a Tech or Engineer but have always enjoyed the electronics and computer world and do my own repairs... My first computer, and wow... this will give away everything... was an Apple II-E with a Monstrous 12 inch CRT Green Screen Monitor, 5¼-inch...
