Most likely the convergence IC's are dragging down the power supply (there are some very small fuses soldered to the board that may be popped), which in turn cause the TV to protect itself by shutting down. But the real cause is old age. That TV is nearing the end of its use life.
I feel bad writing this same response over & over in so many posts, but the reality is, a TV's life expectancy is about 13 years max. Shorter for rear-projection screens, usually 9 to 11 years depending on daily usage. It gets to the point where you have to weigh the cost of today's repair against the cost of near-future additional repairs and compare it to the cost of a replacement set.
Worse, the entire broadcast industry has shifted to HDTV, so the costs of replacement are higher than just buying a new HD set. You need to feed the new HD set with digital cable/satellite, surround sound, a new DVD player, and new cables.
The good news is, standard-def TVs are a dime a dozen these days. Retailers are blowing them out. What cost $800 a few years ago can be bought today for well under $200. The downside of that is you'll be spending $200 on something that will be obsolete well before its 13 years of use life are up.
