My elderly Kurzweil Stage Piano 76 is groaning

I have a Kurzweil Stage Piano Model 76. It needs repair, but I cannot find anyone who
knows much about it here in Kenya. The problem which has been developing over some
years is as follows: Several notes no longer sound properly - they either give
half-sound, no sound, or full-volume sound when lightly touched. This problem has
been getting worse in recent months. What I do to try to fix it is as follows: I open the piano and remove the two large, long, narrow printed circuits and and rubber
connectors (on which the keys press to sound notes) I then clean the connection points -
scrape off carbon etc. This seems to work for a while, however gradually the problem
I have also purchased new rubber connector strips (correct ones) and
installed these. Again the problem seemed solved for a while, but it then recurred.
I note the following: when I screw back the two printed circuits and attach the
rubber connectors (and of course connect the cables) and then press on the rubber
'buttons' (at the point where the keys strike the rubber), I get a correct sound from each
note - touch sensitive etc.
Has anyone any experience of this fault and any
suggestions as to how it might be remedied. I need my piano!!
