panasonic TH-42PZ85UA purple stripe

[pyper]

I have a panasonic 42" plasma tv with a verticle blue/pink/purple (color changes) stripe on the left side. I have changed the SU and SD Boards . The stripe shows up after the tv has been on for about 20 minutes. When I replaced the SU and SD boards it took about an hour and a half before the stripe came back , but it's back on the 20 minute schedule now. Any advise would be appreciated.
thanx,
Lorin

Might be a bad panel, but there's a slight chance it could be a loose ribbon cable. It should be connected directly to the panel, not sure what the boards are called in a Panasonic.

There could be an issue with one of the C boards that runs along the bottom of the panel: Possibly a loose connector, dirty ribbon, or a bad board. In this order of progression, I'd try re-seating the connector, cleaning the ribbon with electronic contact cleaner, or replacing the board. I think bringing up the menu on the TV can help determine whether you have a panel issue or just a connection issue.

I checked all the connections I could see when I was in there before , but that doesn't mean I couldn't have missed something. I didn't take any of them apart to clean them. I saw the C boards when I changed the other 2 boards. The boards I changed seem to be more in control of the horizontal than the vertical. I got horizontal lines when I failed to seat a couple straps on my first installation try. I assume if it was a C Board it would be the one on the side of the stripe. The SC Board was suggested at the time the SU and SD boards were, but if I understand it correctly that board controls the other 2 , so if they aren't the cure it seems very unlikely that their controller could have anything to do with it. I will check out the C Board next., thank you.

I replaced the C-2 board today and the tv has been on for 9 hours straight with no stripe. I think it's safe to say we fixed it. Thanks again,
