Check the mic and connections all through its input into the unit. I would check the cartridge of the mic for continuity for the reason that (I think but not 100% sure) on this model, I think there has to be sound at the mic or it does go silent in vocode mode. This is how it digitizes the mic and keys together. The played keys cannot put onto pitch the sound it is NOT picking up at the mic. I think there is a problem with the mic.
Sounds like a bad rotary encoder (the part that the "dial" is attached to"). If the circuit board or solder is not cracked in that area then that is likely the problem. You could find the part at mouser.com (about $1) and would need desolder the bad encoder and solder the new one in place or get the whole PCBA(printed circuit board assembly) from Korg.
It is possible that there iis a compnent failure in teh POR (Power-on-reset) circuit. This is NOT DIY unless you are adept at electronics. I do NOT have the shematic for this keyboard. I looked at the schematic for a PA500 which MAY be similar and it has a touch screen. SOMETIMES dirt gets under the edge of a touch screens and confuses the processor with a false input. If yours fits this scenariom you might try running a piece of copy paper under the edge where the case hits the LCD screen.
It may not be the pedals as the fault can be oriented within the set. So I think you can open the back of the set and check for all connections to be tight , remove and refit.
If this wont solve it is not adviseable to check this higly intergrated PCB without a help. So consult the Korg service.
You might try to clean it. You can buy some tv tuner cleaner at radio shack. If that fails, then the pot. will have to be replaced. If you can solder and de-solder components its not hard to change out. When you open the unit up, the volume control or POT has a ohm value. Like 200, 250 ect…. It may have a K after it, that’s x 1000. Get the right size ohm value and replace it. Hope this is helpful.
