Yamaha Sy 22 issues

Unread post by OOS » Thu Nov 08, 2018 7:49 pm

Hi all once again

I was given away a near mint Yamaha SY 22 synth that is not working right

at first the "vector" section does not light up while buttons like +/- and </> dont work. Also all C keys except the lower C is not working, also all C major keys not working.

Opened it up cleaned up the rubber contacts on both PCBs and the keyboard, fixed a broken key and the vector stick - the thing seemed that had a quite serious crash i suspect with the company that transferred that cause the owner didnt mention anything about that.

Although i opened it up i can see all cables as they have to be althougth the issue seems that has to do with the "left" PCB board that i not working completely - i can use some other buttons that are on the same PCB though like "Mode voice/multi, edit, store, etc -

Any ideas ?
I would love to make it work OK back again for nostalgia reasons.
