Vintage Synth Repair

Are you sure it’s not the internal battery(possibly a 2032 or other standard computer battery)???? I know when my CZ-101 did this the backup memory batteries were dead. The on board sounds in the CZ-101 were backed up by C batteries. That would be the first thing I would check. If you can’t change it yourself you’ll have to find a local tech to do it.





Cheers,

Your description is not quite exact... I think it's you who should have an idea what happened :-) There's always some reason for such behavior.





One of them, for example, can be that if it was not in use for longer time period, maybe contacts are dirty or oxidized. I would reseat and clean all connectors as a first simple step. Focus on keyboard cables and connectors, I suppose there are some.





Sometimes after the long sleep it's good to leave the machine on for longer time - three days and nights, but keep eye on it and switch off again when you can't stay near it.

Hello,
I have a CZ1 , that was my first synthesizer , but one day I turn it on and if you touch any key , it sounds a very high note and hold on , if you play more keys it adds up but with high notes. If you play MIDI , all is correct, all notes , program change , etc.
Anyone have any idea what can happen ?.
Thank you
