Looking for some help with a 26 Inch Sharp Aquos LCD TV that I have owned for almost two years. Up until this week, I have never had a single problem with it. Last weekend, right in the middle of a show, the TV just suddenly shut off. Completely - the red LCD went out, etc. It was if I had unplugged the unit - which I had not. I checked the connections and everything was fine. I was starting to think that something had blown inside and that the unit was toast until it suddently started up again. It was almost as though it had overheated and then started up again when it cooled down. It ran fine all week and then the same thing happened again this evening. So far, it has been half an hour or so and it has not come on again. Anyone have any thoughts or suggestions? Is this common on LCD TV's? I don't watch much TV at all most of the time - in both cases this has happened after the TV has been on for 5+ hours straight (rare for me.)
