“JX-3P powers on and produces sound. Sequencer works and the synth sounds amazing. It was cleaned and calibrated by Davidson Electronics in NY about a year ago – they installed a new battery as well.
However it seems like there is a power issue. The synth sometimes does not power on. When this happens, if I lift the right side of the synth up (where the cord is), it powers on. Sometimes it freezes up and needs to be rebooted. For this reason, I think the power cord is loose or the power supply needs to be replaced. I am not a synth tech, so I’m not sure. For this reason, I am selling the synth “for parts not working.””
