OBERHEIM SYNTH

A duff regulator could still enable the unit power on, then fail - say the regulator has a faulty solder joint or a crack..  The regulator heats up and the bad joint/ crack widens.

However could be another component.

Good luck 😊

Ps: you could try the Synth DIY and Synth Repair groups

Subject: [oberheim] RE: Repaired and modded Rene's Perf-X Cyclone....

I have an Oberheim Cyclone that powers up ok but freezes very soon thereafter.  I pretty much can't get anything out of it before it freezes or locks up.  I also notice the number LED blinks a lot as well as most of the other LEDs.  I believe the Play LED should blink but the others should not if correct.  I've tried the hard reset, but that doesn't work either.  If there was a problem with the regulator is wouldn't power on right?
