Thanks. The cleaning is a long shot, but is worth trying before I take the whole thing apart.

Thanks very much. I will try the tuner cleaner. It may be a solder connection but somehow I think it is the switch. When I turned the unit upside down to look at the screw configuration the piano mystically turned on. It would then not turn off unless I unplugged the adapter. Thanks again.

My PX-150 has been intermittent when powering up for some time. I would have to press the switch more than once to energize and use. Now, it will not turn on at all. I have checked the cable from the adapter and have 12Vdc going into the piano but the switch does nothing. Is there an easy way to access to change or do I have to disassemble the whole unit?
