Question about Samsung HCM4215W 42" Rear Projection Television
TV turns on and off automatically by it self every few minutes
This is very common in Samsung DLPs. The DMD board may be going bad or it could be one of the fans that cool the engine while it is running is going bad (even though the fan looks like it is running, it is not running fast enough to cool the engine). Just before it shuts down your picture should read at the bottom of your screen which fan is bad. But I have found that does not alway happen.

Had the same problem - though was turning offf less often.
Opened up and sucked out all the dust & dirt I could. Also removed lamp & fan and did the same.
Its been perfect ever since.
