Korg Poly800/EX800 Users

Do you have the correct wall wart power supply?

if you do, then I would next check that the -5V power rail is correct.

And we can go from there after that.

Subject: [korgpolyex] Korg Poly 800 DCO problem
 

Hi eveyone, I'm new to the group.

I hope there's someone here who can help me to fix my Korg Poly 800 
(model: PS800)
I bought it at a second hand store for only 7,50 Euro, but it's not 
working as it should….

I've successfully loaded new sounds to the Korg. but I still hear only 
noises and clicks.

Pitch bend left and rights are not working
Tune slider is not working

DCO with the joystick in up position is not working

VCF with the joystick in down position is working

I've tried to make a sound myself, to see what parameters respond.
DCO 1 & DCO 2 do not respond to any change …..

noise & VCF are working

Could it be that it are just 1 or 2 DCO chips that are broken on the 
mainbord ?

I hope there is a solution for this problem.


Thanks all!

Remo
