Korg DW8000, Mono/Poly, MS-20...

it's out of my league techwise.  I would suggest printing out the service and owner manuals to help you.

I just bought a JX3P and DW8000 locally for a very good price. Unfortunately both were sold in a million pieces. The JX was an easy rebuild/repair and it works great. The DW8000 not so much ;-)

I the digital section seems OK (panel works, I loaded some patches using Sys Ex). If I crank the noise level up I can hear it but no waveform sound. This unit arrived with all the cables off, but I think I have them all on the right places. The SHEN* signal is "stuck" at around 2v. If I bring the signal lower using a resistor I can get some waveform sound, but the patches sound horrible (nonsense). Is there a common failure of that big chip that drives the waveform output? Any other ideas?
