The electrolytic capacitors have aged and there is a much bigger current passing thru them , overstressing the power source an triggering the protection system which shuts the tv off , which cuts the current thru the capacitors, which makes the protection system inactive, which allows the power source to start again a new power - shutdown cycle.
Only when the capacitors heat up from all that current that has passed thru then their internal resistance approaches the normal level so the current drops to tolerable levels allowing the power source to remain on.
Replace all capacitors immediately , or one will fail for good and fry a lot more.

    The capacitors are all over your tv, they are soldered in and they must be replaced with identical ones. If you don't even know what a capacitor is then definitely you can't fix it - take the tv to a repair shop and let them do it. To replace them it will cost you $50 for all the capacitors and the price for 3 hours of labor so go to the cheapest one you can find.

Samsung DLP turns on and off - cycle repeats


make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast.
Call a local tv repair shop to further diagnose the problem.
