Samsung HD DLP Projection TV

[RCAkid]

I realize that this may not be the best forum for this question since this set is only a year old but perhaps one of you might have an idea as to what is going on with this set. Moderator, please feel free to move this thread if you deem it inappropriate to the forum.

I have had this set in my office for about 11 months since new. It has always powered up correctly. I rearranged the office and moved the set home. Now, every so often, when I turn the set on from cold, it will power up and then shut off. Sometimes immediately and sometimes after as much as 5 minutes of running.

The lamp is coming on, the fan is running and the color wheel is spinning (I hear all the motors whirring).

I really haven't a clue what to do with this set short of tolerate it til it dies and toss it.

Any ideas as to what might be causing this?

Thanks!
