Question about Mitsubishi VS-50605 50" Rear Projection Television
After about 5 hours the picture shuts off and the sound works. You use to be able to shut the TV off and turn it back on and all was good. Now you have to wait an hour or so and it work again. If you don't it will work for a couple of minutes and the picture will shut off again. If it helps a while back we noticed lines going horizontally across the screen at the top and bottom in random patterns (black and white). It still does that and that usually tells us the TV is about to go...but the lines do not always show up when it happens. Also when it happens the picture kind of absorbs itself into a horizontal line with 3 colors and then it all goes black. This happens very quickly.
We did call out a service guy and he could not recreate the problem. He noticed a couple of cracks and he soldered them. The problem has not been fixed since we had it happen twice within a week of him fixing it. The weekend seems to be when we see the problems since the TV is on more hours..... any help is appreciated.
Very often older Mits CRT's develope a slow leak of coolant
onto one of the circuit boards....various problems arise,depends
on where the drip lands....even a good tech can miss the drip
evidence.....I have pulled the chassis to the shop only to find
"wet" area under well-lit conditions.................T.
