I think I can get a schematic from them, I guess that's the next step huh? ;) The main problem with one of them is that it'll just keep resetting itself over & over again. Sometimes it goes through it's initializing sequence (self test) and reset. Other times, it'll work for a while (less than 5 minutes) then start resetting itself. It powers itself down & restarts at reset. Maybe that might be telling where in the circuit to start looking for problems? Thanks, - Gnarles

Hi all, Usually, I lurk for a while before making requests on boards but I'm forced to bypass that habit here today. I have a couple American DJ brand "Pocket Scan" DMX lights that are misbehaving. These are small moving head (stepper motor) lights with a couple gobos for shape & color plus a small laser in them in addition to the standard color/gobo lamp. I contacted ADJ, but they refuse to give out anything but a schematic for the units - no service manuals of any kind. They just say none are available. I'm sure when these were the "Next big thing" and new they were available, but not now I guess. Anyone have anything for these things? I'd love to at least troubleshoot the units before I just start throwing money at parts. Logic board assys run over $100 each for these things and they have maybe $5 worth of parts on them.
