Could be the power supply inside the TV is bad. Check with your local authorized Samsung repair center. DON'T try to fix it yourself.

I could be the bulb, but I would put money on the power supply being faulty. It is a common issue with the Samsung plasma's.

It seems that your unit has some sort of Thermal PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. After it shuts down and the faulty component(s) cool down, it restarts again until it once again goes critical and shuts down again only to repeat the cyle.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

POWER SUPPLY BOARD IS FAILING, COMMON PROBLEM. CAN CALL 1-800-SAMSUNG FOR NEAREST SERVICE CENTER.

chances are one of the internal fans is either dirty or failed your should have a tech check and clean or replace the fan

My Samsung 52" plasma TV will shut off while watching TV. It will do it repeatedly and we have to turn it back on. Is it overheating and shuts down? How can this be fixed?
