I acquired a PN80 and it also did not power on. To my *great* surprise the culprit was the on/off switch. It tested ok with a multi-meter but it would not pass enough current to turn the piano on. It was easy to replace - thanks for the disassembly instructions, not sure I would have figured out how it was supposed to come apart without them.
