Sharp Model # 32C241 shuts itself off. When I unplug it for a few minutes and try again, it starts up and runs fine. Has happened twice this week. I'm disabled and money is an issue. What causes this and is it worth fixing?

You could try and switch outlets and see if that helps. If it continues to do the same thing access the T.V. menu from your remote and check to make sure you don't have a sleep timer set. If there is no sleep timer and switching outlets doesn't help then my guess (from my own experience) would be that it's probably on its last leg and would require a repair. If it does require a repair then you would probably have better luck buying a new T.V.
