Thank you voip, i will be ordering a new scope so I can perform the tests you recommended.

Thanks for the detailed measurements. They are helpful. However, notice that IC9 pin 8 and IC11 pin 8 are the positive supplies for these op-amps yet both have been measured at 0V and are shown in the schematic connected to net "[F]". But net "[F]" should be at +5V. The inputs to RA1 are at 4.96V ...

With the DW-8000 in Test Mode, look at the voltages at the various points in the chain, starting with RA1, pin 6, which presumably should be non-zero in this part of Test Mode. Then look at IC9, pin 1; does this change as VR1 is adjusted, and likewise then on to IC9 pin 7. Then pin 14 of IC12 ...

Dear fellow GearHeads, I recently acquired a Korg DW-8000 with no sound, thinking it was just an easy fix because of the well know battery issue. Unfortunately it wasnt! Unit powers on, all leds work, you can change different patches, arp seems to work, Midi i/o works it just doesnt generate any ...
