A word of warning: A television has high voltage and can kill you if you touch the wrong part. My two and a half year old 50 inch plasma is broken already. The Y main or sustain board needs to be replaced. The tv has no active cooling and I'm not surprised it overheated with the tremendous heat generated. Out of warranty repair will cost several hundred dollars. It's a shame they can make such poor quality products. All they needed was a few strategically placed fans to cool the tv. Don't attempt the repair if you are not qualified to do so. The residual electricity from the capacitors, even when the plug is disconnected, can kill you or give you a nasty shock. This video is best viewed on a PC showing the annotations which serve to clarify the locations of different boards and the connections.
