Gnarles Posted January 16, 2006 Report Share Posted January 16, 2006 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.Cheers, - Gnarles Quote Link to comment Share on other sites More sharing options...
ante Posted January 16, 2006 Report Share Posted January 16, 2006 Hi Gnarles,Welcome to our forum,You say anything “but” a schematic; does this mean you got a schematic? If you got it, post it and tell us what’s wrong. Someone here might help you figure out what to do. ;) Quote Link to comment Share on other sites More sharing options...
Gnarles Posted January 16, 2006 Author Report Share Posted January 16, 2006 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 Quote Link to comment Share on other sites More sharing options...
ante Posted January 18, 2006 Report Share Posted January 18, 2006 Hi Gnarles,I have to tell you; I don’t know anything about these gizmos! However a schematic could shed some light over it and attract more members to try to help you. The first thing I would check is the power supply and its connections for glitches since you have sudden “restarts” and resets! ;) Quote Link to comment Share on other sites More sharing options...
audioguru Posted January 18, 2006 Report Share Posted January 18, 2006 I've repaired many intermittent problems just by unplugging circuit boards, connectors and ICs if they have sockets then re-seating them a few times. Quote Link to comment Share on other sites More sharing options...
