Casio CZ/ VZ/ FZ - Pro Series

Hello-- I have a deluxe CZ3000 which plays yet after an initial 
note or two the sounds drop in volume slightly & distort.  Has 
anyone else experienced or repaired this problem?   I realize it 
could be several different things yet am interested in whether the 
problem was fixable, required hard-to-get parts etc.     


Also have The VA-10 voice arranger, sk-1, 5, & 2100 sampling 
keyboards & other casios.....    Have very strange CZ sounds
