We have an older model Toshiba flatscreen TV that always worked fine when connected to cable. We disconnected and moved it to a different room. Now it randomly turns itself on and off, at odd times of the day and wee hours of the morning. I have tried resetting to factory settings. There are no timers set that I can see. I have unplugged and waited, once for several weeks, and we still wake up to find it turned on.
