Zenith C27A24T will power up only after being unplugged for a while
 

My TV stopped working so I thought the power strip might be bad. I
plugged it into the wall directly and it worked fine for 2 weeks. Then
it died again. Unplugging it and plugging it back in helped it work
for another few days. The last time it only would fire up after being
unplugged for several hours and it only stayed on for a minute. Can
anyone tell me what might be the problem.
Thanks.
