I had a friend once describe the Samsung DLP repair process as "swapatronics." You switch out a component and see if that's fixed it. The sets have a robust set of security features that are designed to shut off the set before anything bad happens, should anything "go out of parameter." Sounds like it's not a lamp issue given that you've got a Phillips bulb in there. If you don't suspect the ballast, try the thermostat over the lamp housing. There may even be a way to "jump" this so as to eliminate it's necessity to function. If that cures the situation, then you know that was the issue and you should replace it. Minor expense and easy to change. Oh, and make sure the fans are CLEAN so they're working at max effectiveness. If you've eliminated the thermostat as the cause, and the ballast, then you could swap the fans, but if they're running, they're probably okay.
