A little more info...
The TV is an RCA 32". It shut off again yesterday after about 4-5 hours of continuous operation with no channel changing and no volume change. As soon as it shut off I unplugged it from the inside cabinet outlet and plugged it right back in and the TV came right on and worked fine the rest of the evening. I'm leaning towards some kind of overheating issue with the TV.
I am inclined to think that it is an "auto sleep" thing several posters mentioned. Try doing something simple like changing the volume every 2 hours or so. My Sharpe is supposed to shut off in 4 hours if nothing is changed but it has never happened, my wife changes channels often. :)
Do you have the model number?
