Yamaha Key Contact Board - H - GHL88 X6246 - Replacement Part. One key does not work.

Includes the rubber key contacts.

Suits various models like P45 GHS, DXG etc

Was taken from a faulty piano. A whole octave stopped working and when we open the piano to inspect it, an area of the circuit board was covered in gunk, like a bug had died inside. We cleaned it all off and all but one key from the octave started to work.

Upon inspection it looks like just a single trace is broken.

The picture with the cocktail stick points at what looks to be that trace.

If you are electrically minded, this may be an easy fix.
