I have a Panasonic 47" CRT rear projection HD-ready TV that's about five years old. It's worked great this whole time (aside from when I scratched the screen, doh). Last night I was out of the room and when I came back in, the picture was very dark and the colors were tinted weird, almost as though one of the component cables had come loose. But the problem is evident on all inputs and even when using the built-in CATV tuner. I adjusted the TV so it's almost watchable by turning the "picture" control all the way up and the "brightness" most of the way up, but those settings had previously been calibrated (via Video Essentials) at much lower levels. I figured maybe I lost one of the lamps -- blue and red are strong, green not so strong -- but all three colors are visible. Any idea what might be causing this problem? I do have the service manual somewhere, which I bought to do the manual convergence years ago. I wonder if it has any pointers. Ironically enough, when this problem happened on my living room TV, I was busy setting up a new home theater area in the basement with a bunch of older components I hadn't used in some time. Other oddities are that recently there has been a spider hanging out inside the living room TV, though I don't see how that could have caused the problem. Also last night my smoke detector went off, I thought because there were candles burning in the house. But now, who knows?!
