I did see a remedy at one time, where one would solder a watch batter holder into the circuit to take the C batteries place but now I cannot find it.

I recently came across a Korg Poly 800 on the cheap that had no sound. I worked up a voice on it, shut it off, turn it on the voice is gone. I figure okay, internal battery is dead.

I posted on 4 different sites and youtube and never got an answer. I then grabbed the front post and tweaked it a little by hand.

Maybe I can remove individual keys but from the cursory look I have given it I haven't figured that out yet. There ar...
