I am very sorry to hear you are having this issue. I see from your transaction number that the TV was not registered on samsung.com. I strongly suggest you register on samsung.com so we can access additional information and may be able to assist you.
I purchased a Samsung 51" plasma tv 26 months ago for $856 (with tax). Model # PN51D530A3F. Just got a call from the Samsung authorized service dealer. Needs $350 for "a couple of boards". I don't think its worth putting that much into a repair. Called Samsung. (transaction id 1111808218) and asked them to kick in some to help reduce the repair. They said no. It's off warranty they won't assist me. Posting this in the hopes it might steer one or two people away from a bad product.
