That is a VERY common problem. I had it happen to my Samsung too. The capacitors on the motherboard need to be replaced. Samsung will replace them for free if your TV falls within a certain build time-frame. Mine was NOT covered. It cost ~$200 to fix out of pocket, but you can do it yourself for about $30 if you know how to solder.
Call Samsungs support # to find out if your TV is covered.
