Casio CZ/ VZ/ FZ - Pro Series

Just noticed that the definable slider only runs from 57-99 instead of 0-99 - another slight bug.

    Further update -after changing all the display transistors - I finally tracked the problem to VR1 - which adjusts the voltage to the LED supply circuit - being set too low. Once altered - the display returned.

Everything now works,apart from the MIDI channel set button - which is a bit strange,since the button itself seems to be okay,whilst this is a minor fault - it is a tad irritating. No doubt I will track it down in time.

I am writing a report on the findings at AZ for reference.

    Az is rated at 1.3 w. the casio dg I am working on is rated 4.3w and works off the power bank easily. The dg also uses big fat round batteries, whereas the az uses thin penlight batteries.
If there was a current problem then the power pack ought to fail the dg10 too, which it doesn't.
W=IV
I=W/V
Current for dg = 477maFor az = 144ma
If anything the dg needs a better psu. The az should be ok?

That doesn't sound like anywhere near enough current. Try something like a 1A supply.
