Just wondered if anyone can help, ive got a 51" samsung ps51d550c thats faulty
no picture or sound led light flashes, looked inside no blown caps but found a short on one of the chips on the buffer board and im assuming the y sus board has gone as well,the logic board led flashes every 6 seconds which seems to confirm a bad y sus board , if i remove the power cable from the power board to the y sus no difference if i remove the ribbon from logic board the led flashes every second and the screen starts buzzing like its trying to power up. After all that my main question is, when i tried to order the b y sus and buffer board from a lcd parts company i was told that the plasma panel on my series of tv will be defiantly have failed and will short the new buffer board and y sus, so if i replace with good boards it will do the same, is this true and if so is their anyway i can find out if the panel is bad or not before buying new boards?
