This particular Yamaha Head I/O Board is a common failure. Yamaha supply an updated version which is less likely to fail. The cause of the problem that you see is due to the connectors on the flexing and damaging the inner layers of the board. The only cure is to replace the board. Note: You must adjust the lighting pots on the replacement board. You require the "Light Adjusting jig" to do it.
