Archive of the former Yahoo!Groups mailing list: Yamaha CS80

i bought a near mint CS60 yesterday, looks nice with my CS80.

But the CS60 has a few (minor problems) the aftertouch for instance is
always on. Any touch response settings are directly audible, when i
press the aftertouch nothing happens. I know that the aftertouch works
with a light bulb. I opened it up the light bulb still works, if i put
a piece of paper between the light and i think the sensor then the
touch reponse stops. So somewhere there is a fault perhaps the sensor?

Does somebody have any experience with this problem, can i fix it
myself or do i have to bring to a (experienced) technician.

Thanks in advance,

Alessandro
