Casio CZ/ VZ/ FZ - Pro Series

It doesn't sound like its almost working normal at all, in fact it sounds like the relay did nothing to change the volume, and I don't see why it would.  I think you got some bad advice there.  I'd look for a bad op-amp or amp chip, or a cap next to an op-amp or amp chip.

I turned the internal pot meter clockwise and I would almost think that it is working correctly. So it started to sound even louder. However, I know that that ain't true.

The relay in the CZ is an Omron  G2VN 237PL 5VDC.  Omron doesn't make this anymore, but there is a suitable replacement (G5V-2-DC5). You can buy it at Mouser.com or Digikey etc. http://parts.digikey.com/1/parts/756919-relay-dpdt-2a-5v-50-ohm-coil-g5v-2-dc5.html. No need to pay a tech for this repair job - it's a very easy fix - find a friend who can solder if you can't do it yourself (or use this as a chance to get your feet wet).

First remove the 3 screws on the bottom sides of the CZ-1 (actually, one of these screws on each side is on the back since the piece is L shaped).  Then just remove the Four screws on the ledge under the Casio logo on the back.  The top piece will then just lift off.
