James, does your control unit have a “Voice” button? If so, when you push it, is there an option to set “PianoTone” of On or Off? You might check that.

Recently I went to use the silent piano for the first time in a few months and there was no output. If I adjust the settings to play the XG sounds I can hear them fine. MIDI output from the keys appears to be working, and I can play / record and the keys all move etc.Is there something obvious I might be overlooking? If not, what is the prognosis? Is it likely that a repair is going to be cost effective on such an old (and essentially worthless) instrument now?Many thanks!James
