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.
