Technics KN220 keyboard

[Geir Holmavatn]

Hi,

It suddenly cut off one of the speakers. I have tried to replace the
audio power amp, but to no avail. There is a slight hiss in the 'dead'
speaker.

Anyone having comments, tips on where to search, or even better a pdf
service manual for this keyboard.

Thank a lot for any help

regards

Does it have a headphone socket that cuts out the speakers? Could be just
that the socket needs cleaning.
