The problem has gotten better, before the cans would flash continuously, nonstop, until the affected light's faders on the DMX operator were brought all the way down for a few seconds, then back up. I thought the problem was in the cables we had, so I replaced the XLR cables with proper DMX cables and added on a terminator, this resulted in only 3-4 flashes after coming out of blackout. It also occurs when switching scenes too, I go to a scene that has the cans on full and the same 4 cans flash 3 or 4 times.
For some more detail on this, I use an ADJ DMX Operator, which controls: x6 ADJ Flat Par TRI7X LEDs and x2 ADJ DP-DMX20L 4 channel dimmers that dim x8 PAR-56 cans. All the lights and dimmers are on two trees: 3 LEDs, 1 dimmer, and 4 cans per tree. The flashing only happens to the 4 cans on the right tree.
I'm at a loss at what to do now, I've checked the channel numbering and all that, the show is tomorrow night so I need to diagnose this fast.
