Casio CZ/ VZ/ FZ - Pro Series

I remember having a problem with the relay in a CZ-1 once. The output sounded distorted. I think I fixed the problem simply by cleaning the relay. I can't remember if I just cleaned the solder joints or if there was a way to take the plastic cover off of the relay and spray some cleaner in it. I don't think it was a solid state relay.
   
  Anyway, cleaning or resoldering is easier than bypassing the relay. To bypass I imagine you would need to take it off the board and jumper the audio input of the relay to the output, but without a schematic at least I couldn't tell you exactly what to do.

Great tip, I'm investigating just now. Yesterday, magically it worked 
for some hours, so I'm pretty sure the bulk of the synth is in perfect 
condition. What would be the best way to bypass the relays? Thanks a lot :)
