The A key and D sharp keys on my yamaha clavinova 120
in every octave have stopped working. Would really appreciate any advice. Thanks
@smcd you need to start disassembling and take a look at the ribbon cable connection the keyboard as well as the membrane for the keyboard. Post some images of what you find with your question so that we see what you see. Use this guide Adding images to an existing question for that. You are looking at something like #230 in the diagram
