Repair of a Yamaha Clavinova CVP 30
For a Yamaha Clavinova CVP 30 out of order due to the failure the chip "XC711A00" located on mother board (electrical function: SFD-2):
1. Could you help me to provide this component somewhere (or an equivalent replacement part)?
2. In case of impossible replacement could you help me to provide an electrical diagram of the electronic functions to tentatively replace this component by a "hand made" electronical equivalent function?
