Cyberlight issues

I have 4 Cyberlight Turbo's and 6 CL's. One of my Cyber Turbo's,when started up, will go through its homing procedure, then will start going wacko. Mirror will constantly move, color flags, color and gobo wheels move, focus in and out non-stop for about 5 minutes and then it shuts down (the lamp does strike BTW).

A few of my CL's will do the same thing, however after 5 minutes (or longer) they will settle down and behave normal thereafter.

Do the IC9 chips come into play in any of this? What are the effects of a bad IC9 chip, or one that's going bad?
