Yamaha Motif ES8.... 7 keys make no sound now

[jimrbob69]

I had a B key that was sticking, so I shut off keyboard and sprayed some contact cleaner on the sides of the key and that freed it up. I waited half an hour and then plugged it back in. Now A flat thru D make no sound at all.,..what did I do? What could be the problem?

What could be the problem?

Uh, you sprayed contact cleaner where you shouldn't have?

IF the key was sticking because it was full of crud you succeeded in washing the mess directly under and inside the rubber contact strip.

They use conductive silicone rubber switches on virtually ALL electronic keyboards these days.

Contact cleaner is meant for METAL switches...
