    Chauvet Q-spot 575 startup issue

    The driver chip is brand new, I guess I have not verified that it didn't burn up right away but the driver should be good. There is no obvious sign of any components being bad... no burned or signs of arching on he board. Usually I have found that if a component like a capacitor is bad it is...

    Chauvet Q-spot 575 startup issue

    So, an update... I replaced the driver chips for the pan and tilt motors, and I replaced the fuse that was blowing as a result of the bad driver chips. For the most part, these lights are now working properly. One fixture is 100% working and all good. The other one now boots properly and is...

    Chauvet Q-spot 575 startup issue

    Which board is the Lamp control board, if I don't sound too dumb asking that question? I'm assuming it is one of the boards in the base of the fixture, correct? Any idea what the price would be for that part? I would ideally need 2.

    Chauvet Q-spot 575 startup issue

    Done. I got the heat sink off and am able to get the drivers. I will post again once I try a few more combinations.

    Chauvet Q-spot 575 startup issue

    There is no sign of any burning anywhere on the BCB. The Stepper drivers are a definite possibility. Any idea what the actual part number is on the stepper driver? Chauvet Parts doesn't have much for these lights anymore but I'm sure I could get these drivers from Digi Key or some other parts...

    Chauvet Q-spot 575 startup issue

    Hey All, I am writing again with the hopes of getting some more ideas as to the problem with my Chauvet Q spot 575 fixtures. I first posted in this forum a few months ago and since that time put the fixtures on the shelf and left them alone for a while. I dug back into them this week and...

    Chauvet Q-spot 575 startup issue

    Nothing comes up on the display. From what I understand, these fixtures strike the bulb first and them go into to boot cycle. Once the boot cycle is complete the fixture will go to its home position.

    Chauvet Q-spot 575 startup issue

    Hey All, I have a few Q-spot 575's in my inventory, and I am having an issue with one of them. Now I know that these fixtures are quite old, and I don't have much hope of getting them working again but I thought I would try anyways. One of my fixtures fails to go through the boot cycle. I...

    Martin MiniMac Pro-bulb fails to strike

    Hey All, I have an older Martin MiniMac Pro that I have had for a few years. I bought it used and it has had numerous problems over the years but I have used it for a number of shows. A while back it quit on me and I put it on the shelf to fix when I had time. I have been working on it...

    Automated Fixtures Martin Roboscan Pro 218 MKII with problems

    The motors are not locked. This was one of the first things I checked. I think more than anything my issues is with why the 2amp fuse on the board is blowing. The fuse blows with or without the pan and tilt motors plugged in, and I am assuming that power is supplied to these motors through...

    Automated Fixtures Martin Roboscan Pro 218 MKII with problems

    I built a pin 2/3 switch cord and this fixes the dmx problem. I am still blowing the 2amp fuse on the mother board and have no pan and tilt. The motors are not getting any power. Does anyone have a wiring schematic for this light? Other than the pan and tilt all functions of the light now...

    Automated Fixtures Martin Roboscan Pro 218 MKII with problems

    My fixture is for sure a Mark II, at least acording to the Martin label on the top of the fixture. The xlr jacks on the top of the light do say Serial Data Link... this concerned me a bit, but after reading through the manual I thought it was dmx. I will try the pin 2/3 swap and see what happens.

    Any idea of what kind of a short I am looking for? Broken wire, bad motor..?

    Automated Fixtures Martin Roboscan Pro 218 MKII with problems

    Hi All, I am new to this forum and and looking for some answers about an old Roboscan 218. I recently acquired this light on an auction for $10 in a partially non working condition. When I power the light on, the bulb strikes, and the fixture runs through its startup. The issues i am having...
