Korg Poly800/EX800 Users

Which switches work and which ones don't? Be specific.
While it is possible for the switches themselves to have problems. And we have a document for how to clean them if you check out the EX800 servicing section of the files area of this group.
It is also very possible that your wiring harness, the connectors, the wiring plugs on the main board or even the matrix switching chips may have faults.
So before you go tearing yourself up looking for a switch that simply is NOT available anywhere on planet earth, tell us which switches are not working and which ones are.
Also tell us if they sometimes work if you push harder on some of them.
Also go read our PDF on how to service them.
