Our Colorsource 20 board has been operating fine until recently. In playback mode our fixtures (Elation Fresnel KL8's and KL6's) will turn on with the assigned playback fader, but 6 of our 15 fixtures will not dim or turn off in the same manner. They will not turn off nor dim unless I go into the individual channel mode. And when I go into the channel mode none of the faders indicate that those particular fixtures are even on. I have to use the channel faders to turn them on and only then will the fixtures turn off. Any ideas what could have happened? Would a power outage or anything like that cause the board or the fixtures to behave this way?
Thanks!
