My school has an ETC 24/48 lighting system with two moving lights. I've heard them called IQ's but in case that's not a good name they are essentially mirrors placed in front of the lights. For several years the system has been set so that one fader can control the light while a set of two others control the mirror in an XY-fashion. Suddenly both of the lights with mirrors aren't working. The light turns on but the mirrors don't move. I'm not sure what the problem is and hope someone here could help. I'd say the most conspicuous thing is that the problem came to both of the lights at the same time. I believe it has something to do with the way the mirrors are connected to the channels but nothing else is really out of the ordinary on the board so I kind of doubt hardware. Any help would be appreciated and, as you can probably tell, I'm not too experienced.
