The way I am using these fixtures is thru a DMX relay to take advantage of the built- in sound activated programs and Blacking out fixtures when a DMX signal is present. Every works great but one fixtures does not lite when switched. If the fixture is reset it will work for a while but have no light output intermittently? Was just going to try to narrow it down to a board but not sure which one would control led light switching... Thanks for the replies!

Thanks for the reply...I have tried Factory reset. It works for a while but when turned off and back on this fixture sometimes does not turn on (no light... movement ok)

I am going old school and set up some Martin mulitbeam 2's (16). 15 work great but one does not. When it switches from "black out" or just powering on the fixture I have movement BUT no light output from any leds. If a reset is performed the fixture will work properly until the next blackout or power cycle? Has anyone come across this? Would replacing the main board (Main board Multibeam 2 50480669) control the switching for lights on? Thanks Ed

Technical Support Engineer Harman Professional Solutions: "I would inspect all connections to the thermal switch (you will need to pull back insulation to expose wiring around thermal) and main PCB. We have seen the connections deteriorate over time and have to be redone " I just have to get to venue and get it on the bench...

Thanks for all your help. I will try to call Martin (or whoever is there now). The remote is directly plugged into the back and unit does have dip switches for DMX. Like I said its an intermittent problem and ONLY does NOT work when I need it the most...

Boy its starting out to be a rough year.... I have a Jem ZR33 fogger that works when it wants to... The ready led on the back works intermittently. When powered on and after heat up it would come on and work fine all night. Next night ... turn it on, it heats up(>30mins) (can feel heat thru from front of unit)... NO "ready" led No Fog output Checked "thermo breaker" under front cover ... not tripped. Next night works fine? Has anyone worked on these bad boys or any ideas on what to look for. Thanks Ed

Thanks for all your help. I can see where switching one leg would be a problem. Sunray...love the relay...(and the drawing)...I will try to find one available closer to me! Ed

Dave would this work? Can I just switch the "+D" of the DMX signal? https://www.ebay.com/itm/313415418929?epid=11012071349&hash=item48f903c431:g:wyQAAOSw9vdgJVMu

Thank you sir !!

Do they make such a thing? Or do I break out the soldering iron? Would there be a problem switching the DMX signal?

Thanks for in info...the fixtures were gutted with missing gobos...but love the 3d blocks!

Just finished repairing a few technobeams and they are missing some gobos. Can anyone recommend some gobo images that would look good in a club type venue. Thanks Ed

Does anyone have or programmed these fixtures? I have 6 of these in a club and they have some nice "Master/Slave" programs but are not accessible thru DMX (still using old Lightjockey). When running their macro ... they all do their own thing (looks bad ). Anyway these fixtures CAN RUN their stand alone programs IF the DMX signal is lost! Is there a device than can "break/switch" the DMX signal to that separate group of multibeams ... controllable thru the lighting software???? Thanks for any help Ed

Thanks for all your help ! Voltage good....Ordered replacement chips to try. Ed

I took one of the strobes apart. There is only 2 socketed IC on the board. Would the MC3405OP the chip I am looking for???
