Discussion about the Korg PolySix synthesizer

Hi folks,
my name is francesco from italy.... i have repared my poly6, but all
led is on.... oldcrow says bad cpu...

possible solutions?

sorry for my 'maccheroni' english! :-)

I guess adjusting the "Reset Adjust" trimmer could solve the problem,
but you'll have to verify. This is how I solved it on my Trident.

If the battery leaked then it is likely that IC30 & IC31 on KLM367
will need replacing. You may have some tracks that have corroded too
that will need repairing. These devices are connected to the D/A and
are important for the correct function of the programmer. You will
also need to check that the D/A is set up properly once you have
completed a repair like this. I believe you can find this somwhere on
www.synthzone.com
