I have a 32" Panasonic TV approx. 10 years old. It turns off at random. Do you think it might be a fuse? Sometimes it stays on 20 min. and sometimes 2 hrs. before it happens. Suggestions?

Two immediate suggestions.

1) Power supply failure of the TV.
2) Loose connections at the receptacle outlet. Turn power the circuit power off from the main panel. Remove the receptacle faceplate and the receptacle. Check the wires for loose connections, charred or burnt insulation as well as checking for Aluminum versus Copper wires.
