I have the Samsung LN52A750 and when it's off and you turn it on it clicks off and back on a few times before staying on. I unplugged it but nothing helps.
Does this occur if you disconnect everything but power? Does it occur on all sources and inputs? Have you tried using a different surge protector?
Yes. This problem is known by Samsung but you can see by the stupid response I got they still sweep it under the rug. It is a defect in the power board but Samsung won't fix it without paying for service.
