New Samsung LN52A750R turns itself off and on

post #1 of 2
Thread Starter 
I just bought this tv this morning and it constantly turns itself off and back on. Sometimes the screen turns a pixilated purple/pink color just before it turns off, sometimes it just goes black. It goes through this cycle every 5-10 minutes.

I have checked the timer and it is not on. Signals are fine from the cable box or dvd player. Is there anything that i can do, or is this a case of buying a bum tv?

Thanks for any suggestions or advice.
