My DX-7 took a spill on tour and broke a few keys, no problem ordered a few replacement keys. However the rest of the keybed seems to not be working now and it remains an enigma. Haven’t owned the synth very long so I’m wondering if someone else here can help me with this issue to get it back up and running again.
typically, does it power on, and pass the tests?
will it play though midi
recheck the keyboard connectors for broken connections.
recheck the fuses,
Do you have a schematic? I cant figure how to upload pdf file yet.
