I have a 7 year old Mitsubishi 55" HD Rear Projection TV that looses the picture after being powered on for some time, the sound stays on. It comes back if I let it rest for a bit.
Sounds very typical of a component failing after heating up for a bit. Often in the Power Supply or Horizontal Output section, WE find the offending component(s) usually by using a can "Freeze Spray" and spraying suspected compnents when the problem stops thats ya faulty one... replace it/them and usually thats it. But if ya no good at doing it yourself.. then it's off to the shop... Generally because of ther size these beasts cost a bit to fix.. If ya have to take this route, ensure ya get a firm "Quote" AND an explanation of whats what. G L. Oh and offer to take it to the Shop, this will.should save ya some $$'s
