Out of 7 Casio ctk 810 keyboards we bought earlier this year and used in a school keyboard lab, 4 have got stuck on various volume levels from zero to full volume? the Yamahas we use are fine.Any ideas?

Yes spray some contact cleaner into the switch while unit is off. move it back and forth spray a little move. dp this a few times. this will clean it up and it should work better. Get this stuff a Radio Shack. $8.00 a can. I use this stuff on all kinds of electronic;s. Like a stiskiy keyboard button, so forth.
Good luck DFD
