Hi guys
just found a casio MT-46 (45s are the same basically) in a cupboard. The 'accompaniment' works perfectly, but the 'right' or 'melody' part of the keyboard makes no sound what soever.
I openned the keyboard and all the wires looked fine (thought it might be a broken ribbon cable) and the PCBs all look good. anythought on what might be wrong? any leads on a service manual?
found a user manual on the net, just not the service one. with a circuit diagram i might be able to follow the signal to where it should come from.
Thanks in advance
