    Greetings all.

    I was in the middle of using my board and then all of the sudden all the keys stop working except for the Gs & D flats. I was in voice mode. I tried a factory reset and that did not work either. Literally have no clue what could have caused that. Has anyone even heard of that?

    Open it up and use contact cleaner on the molex connectors connecting the keybed contact boards to the motherboard.

    It's probably oxidation on the connecting pins blocking proper contact.

    If it's still under warranty contact Yamaha for service.
