I have this problem often. I'm not sure but I think it's the fan that cools the light. I say this because when I reach my hand in, the fan seems stiff. I vacuum out the dust, and I spray some WD40 in the fan from behind the rear housing. There's been times where I did this twice before the fix took. I really don't know if this is the problem or not. All I can say is that the TV has quit about five times now and I'm watching it as I write this.
Maybe it's some wiring and pulling the light out and monkeying around gets the "short" fixed. Who knows. It does seem like the fan though. When it finally quits for good I'll try replacing the fan. Maybe I'll even replace it before it dies completely who knows. For now, the quick fix works and I'll take it.
It sure beats taking it to a repair shop. I do almost hope it dies all the way so I've got an excuse to buy a 60" Samsung 240 hz refresh rate. What stops me now is that the picture on this Sony kds50 a2000 is really quite nice. It's not as cool as a state of the art Samsung, but hey, it's five or six years old and paid for a long time ago. It's hard to beat one of these old kds50s.
