Our Samsung CW21A 113V telly switches itself off completely after varying amounts of time. Sometimes it lasts for about an hour, sometimes less. When it turns itself off we have to go to the telly, switch it off and back on again. First I thought it is due to overheating, but I doubt it that it can overheat in about 10mins. That problem started about 2 months ago and for some reason sometimes it works better than at other times and when you switched it back on about 10 times it stays on (nothing to do with the room temperature). It's not an old telly, too, maybe about 2 years and it is well annoying.
