I have a panasonic TV that's about 5 years old. It will cut off and stay off for a couple of minutes and then come back on. Does it a couple times, then stops. Ive unplugged it, and left it off for couple hours.. and that does not help. I don't think its getting to hot. Any suggestions?

Model number? Any problems with anything else in the setup? Is it plugged into a surge protector or power conditioner? Is there any error messages on the screen or any flashing/colored indicator lights?
