Greetings
I've repaired several of these machines....the GROUP Korgpolyex has tons of past
forum discussions about the usual ailment with these.....most often just the internal
3 volt Lithium Battery on the main PCB is dead, losing all its presets......so there is
nothing in recent memory to work with, thus it appears dead, but in all probability you
just re-program into "11" any voice parameters that produces more than noise......
then save this to a differnet patch#, and then youll know if its worth while to proceed....
If that works, then install a new battery onto the circuit board and program the remainder
of the patches......check out the files area of this group , as well
Cheers,
Dan
