Hey I have a pn60 and when I turn it on it hums loud at first then fads away. There is no sound coming out of the speakers when keys are pressed. All lights and bottoms seam to work but no sound. I have removed the board as I think it mite be the amplifier chip. What are your thoughts? Any place I can get service manual or info on board diagrams?
