Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way
