Question about Samsung HP-R5072 50 in. Plasma HDTV
There are a couple of possible causes for this, but my first suspect would be the main/input board. There are a group of electrolytic caps on that board, any one or group of which are probably failing, and my gues would be in and around the micom IC3003. This would cause the video or audio signal to be interrupted or distorted and if the signal processor sees nothing, nothing is exactly what the processor displays. unfortunately this repair is not for the less than technician. To repair that board a tech will use several tools far more expensive than the TV itself when it was new. On top of that it's not a repair you would trust less than a CET to perform. That said, it's not hopeless and far less expensive repairing it than buying a new one or half of a new one. So my best suggestion if to have it repaired at a reputable shop - one that specializes in plasma repair is preferrable. If you're not sure how to locate such a shop contact NESDA http://www.nesda.com/locator/state_search.php and research a servicer in your area. Hope this helps. Bill
