THE STORY: Picked up a Korg DS-8 the other day whose user interface is completely unresponsive. Powers on with a blank LCD and all right side LEDs frozen on. Looks like something may have been spilled on it many eons ago =/
I've cleaned and inspected all the PCBs and gone through the whole thing with a scope and meter. All the voicing circuitry and digital clocking seem to be fine, it's just not able to boot up properly. No signs of stress or thermal damage around any of the components. With only a partial service manual, I can only speculate as to the function of some of the larger, more proprietary ICs.
THE PITCH: I'm hoping someone here may either A) have some experience repairing this synth and could help me troubleshoot, or B) knows where I can source a new Main PCB (KLM-1071C).
Thanks in advance!
