Casio CZ/ VZ/ FZ - Pro Series

I haven't seen a schematic, but generally there's a circuit that will only allow the CPU to operate once the power supply has stabilized (so that it works properly when you turn it on).  If the power supply is marginal or has an intermittent connection, it could cause this.  It could be something else, but this is probably the most obvious place to look.

            Any idea what's causing my CZ to randomly re-set itself??



It turns on fine, and plays fine, but every now and then, it will 

reset itself, and go back to internal patch A1 (Brass Ens). Also, the 

Tone Mix, Key Split, Normal and MIDI buttons are always lit, but can 

still be used. 

Very strange I know, my first thought would be a power supply issue, 

but the button thing makes me wonder. Of course it could be unrelated, 

but I'd like to see if anyone else has any ideas.
