Technics KN6500 keys troubleshooting

[slgroves]

I have a Technics KN6500 and a few of the keys are not playing right. Sometimes they don't play at all, and sometimes they play very loudly, and sometimes they play just right. Solutions? Is this something I can fix, or are there repair people around (I'm in Eastern WV)? Is it worth trying to fix it?

Yes.

It looks to me as contact problem (cleaning??)
Always the same keys?

Yes
