Casio CZ/ VZ/ FZ - Pro Series

My problem with my cz 5000 is that after it begins to reset to A1 without
pressing any button ( it resets sometimes continuously , i turn off the
synth and it stops , but some minutes later the problem returns ).


Some days later the problem stoped and the synth begins to demonstrate other
problems like strange sounds , polyphony reduced to mono and no button
responds. i turn off the synth and turns on . The problem disapears for some
minutes.

These problem begins to apear after some days that a ised the Cz 5000 for a
long time of programing ( 3 or 4 hours playing with it without turn off )
