Is my Yamaha CS01 braindead?

Post by iamrcb » Thu Jul 01, 2010 9:47 pm

I was messing around inside my CS01 earlier today looking for usable circuit bending modifications and I think I've shorted something pretty important. Now it doesn't make a sound! I can coax a constant, low volume high-pitched whine out of it that the filter will act on by nothing else.

Any tips on possible remedies or have I foolishly blown a critical IC?

I know your post is an old one, but I'm sort of in the same situation, and I was wondering if you ever managed to solve the problem, and how?
I wanted to add a midi retrofit to the cs01 mkII's board, I followed all the steps (in my eyes) correctly, but somehow I ended up wrecking my first and favorite synth.. I'm gutted..

So please tell me, is there hope?

You have not provided enough information for anyone to diagnose it. It's possible you overheated a component, or damaged an IC with static, or cut a wrong trace somewhere. Do you have the service manual? IC datasheets? A DMM? Can you undo the MIDI kit and go from there?
