Something is causing the power supply to shutdown. Lots of things can cause this. A service technician will probably need to look at it.

John,

While it could be a component failure...

More than likely there is a cold solder somewhere in the power section.... Most electronics are asoldered using a process called "wave" soldering.... Thing is If there are LARGE and SMALL items on the board.... The BIG items don't get a proper solder. (If they did the HEAT in doing so frys the small components)

PS: Sometimes when things like this happen, it doing so will fry something else...

If you're lucky you may be able to remove the board, inspect, and resolder.
