Wasn't sure which section to post this in...
Having a problem with my trusty Panasonic TC-P50U1 50" plasma. Wondering if anyone has some tips. It's about 8 years old and kind of out of date, but the picture is (normally) great and I'd hate to replace it if I don't have to.
I moved the TV a few months back, and after setting it back up, there was a small red vertical line in the screen about 1 pixel across. Hardly noticeable most of the time.
Last night, there was some sort of a "fizzing" noise that lasted a few seconds (not exactly sure, paraphrasing the girlfriend who was watching it alone at the time), and the red line turned into a wide black bar with some fixed lines of color:
I popped open the back and identified the ribbon cable that controls that portion of the vertical axis. When disconnected, the exact same portion of the screen turns white(ish):
It concerns me that it's not completely white -- I hope the black splotches don't represent some sort of failure with the panel itself.
This is the ribbon cable that controls this portion of the screen once I unplugged it (far left on the bottom):
There was a good bit of dust, so I blew out the connector and wiped the connections on both sides with some rubbing alcohol.
Another overview shot of the back (sorry for poor quality). The affected cable is just to the left of the little metal vertical support on the bottom, slightly to the left of the photo's center (if that makes sense):
Any tips? I thought about ordering a new control board (or whatever it is that the ribbon cable plugs into). There are also some small chips (ICs) on the cable itself, so I don't know if that might be the problem, and that seems like a pain to replace.
Figured I'd ask before I start throwing money at parts that might or might not work. Don't know how common this problem is.
I'll get a new TV if I have to, but I've always liked this unit and would love to figure out a fix if at all possible.
Thanks!
