This is a strange one. My board op was running cues and found that midway through the show a number of lights from different dimmer packs came on during a cue that was supposed to be a blackout. And they stayed on. She turned the breakers off and on again, and the problem disappeared. Had an earlier prob with lights coming on after power down, but that may have just been improper shutdown. What about this lights up at random and staying on? Does this sound familiar to anyone?
