Hi ! I just bought a Yamaha S 80 keyboard but I have e few keys that dont seem to want to work unless you hit the key hard. I openned the unit up and cleaned it
but I think the rubber strip where the underside of the key hits might be worn. I'm just guessing here.
Thats the only thing I can think of.
Any input would be great!! Thanx
