The Kawai & Teisco Analog Synths Group

It doesn't work because the battery for memory backup has been dead for years and emitting corrosive gas into the circuitry of the machine. Open it up and look for a blue cylindrical thing on the cpu bd (looks like a certain type of cordless phone battery, about as big around as a quarter and an inch or so long). More than likely you will find that on the ends (mainly the "-" end) there is a mold like substance. Now look around the surrounding area. Does it look like something was spilled onto the board in that area? That's corrosion damage to the board and its components due to the gas coming from the dead battery. It's possible to repair it, but sit down when you get the bill. Very time consuming and there's no guarantee it'll ever be right again. I recently gutted a Korg Poly 61 because of this. But that's ok, the poly61 sounds like shit and I needed a keybd/case donor for a synth I'm building anyway.

I repair these and if you are serious about getting it back on the road again we can talk.
