Casio CZ/ VZ/ FZ - Pro Series

I was going to mention what I had noted on the CZ 1000 - when switched off without any power backup the pitch defaults to a high pitch as the pitch bender data (I think) is corrupted - the result is similar symptoms to those described here for the CZ1 - rolling the bender (I think)
 or carrying out the reset procedure puts it all correct.
Whether or not it is relevant to this problem,it's a tad odd that the unit does not default to a playable state. I presume there is a CR2032 hanging about in there with no juice left as the 101 doesn't do this,unless it has non-corruptable memory?
 
The initialization procedure is the first port of call I think.

Not too much information to make a diagnosis from it.

- How did it start?
- Only one key or any key? 
- Which key?
- I more keys are out of tune, is there some pattern in it? Like the same key in each octave, or every fourth or so?
- The sound is always the same pitch or changing randomly?
- Which pitch is it, how high?
- Is it in the same timbre as other keys playing normally, or some different timbre?
- Is it the same on all sounds (memories)?
- Is it the same with preset memories?
- Does all the other functions and parameters on synthesizer work?
- Have you tried initialization function?
- Are you sure power supply is OK and all voltages on spec? Have you done recapping? 

There can be more questions...
