Hi all,
I'm hoping to get some of your insights with regards to a strange screen issue I'm seeing on my Samsung PS50A plasma screen. It worked fine when I last turned it off, but yesterday when I turned it on, it went straight to a weird screen, which I would describe as "black and white only, with random horizontal black lines across the screen, in more or less fixed positions". I still have sound, and the TV is still responding well to the remote. You'll find attached some pictures for your reference... Note that I do have some color when I switch to a channel without signal (see attached picture).
Maybe good to know is that we just had a few hot days outside (30+ degrees) where I live, and the TV is standing directly in front of a window. It's the only external influence I can identify at the moment, that could've caused something.
I've read the plasma troubleshooting guide, but unfortunately didn't find a conclusive answer (yet). I've done the following so far, with no results:
- Issue persists on all channels and input sources
- Power cycled the TV multiple times
- Verified fuses on the X sus and Y sus boards
- Reseated the main connectors between the different boards
- Visual inspection with back panel removed - I found one slightly bulged cap on the X/Z sus board, but I'm not sure it might be causing the issue?
Any ideas or suggestions are welcome! Thanks a lot!
