Hello guys,
Yesterday all the buttons stopped working, nonetheless, the on-off switch works, as well as the volume knob, so I can still use the piano in the default mode (Grand Piano). The lights on the panel turn on normally, but buttons don't respond nor do anything at all (display/lights don't change).
I didn't do anything strange to the piano, it just happened out of the blue.
Any ideas or possible solutions? I checked and there is no operation lock on this model.
Thank you.
