Casio CZ/ VZ/ FZ - Pro Series

I'm going to chime in with the same advice I always give.  You may have 
already tried this, because it's really basic and simple advice.

Make sure you intialize any used Casio you get, or any Casio that you 
take out of storage.  I have had exactly similar problems to the one 
you're describing, where the wheel seems to work but the data it 
transmits is screwed up.  Initializing the machine resets all the 
internal data.  The problem you describe sounds more like a data problem 
to me, rather than a hardware problem.

To initialize the machine, turn it on, flip it over, and press the "P" 
button with a long, thin implement.  This has always cleared up a wonky 
pitch wheel for me.

You probably already tried this, because you know your way around 
electronics.  If so, disregard this message.  If not, make sure you try 
it.
