Television and Home Theater

My TV used to shut itself off every so often for a few seconds and then it would turn itself back on.  It would stay on for an hour or so and then do the same thing over again. This went on for weeks until now it has turned itself off and will not come back on at all. I tryed turning it back on at both  the TV and the remote but I still get no response. The TV was manufactured in 2001 so it's only 5 years old.  I bought it new 4 years ago.
