I bought my 56H80 a little less than a month ago and it has not been on for more than a two to three hours per day (+/-). Yesterday, as I was watching it, it all of sudden turned itself off and back on momentarily, and when it came back on it had switched from TheaterWide to Normal. My wife said that it did it once again today, although I haven't seen do it tonite, while I've had it on for the last couple of hours. I'm getting a bad feeling about this!! I hope I don't have one of those Toshiba quality problems I've heard about. Anybody else experience this problem? What is it? Could it a power fluctuation? Any feedback would be appreciated it.
