    Hey all
    I have some VL2000s that were packed away about 7 months as working but now I have one, so far, that isn't turning on.
    It seems like an old PSU, but want to confirm here.
    When I turn it on, theres a subtle click and one of the lights on the LCD flashes. When I first plugged it in, the click was quieter and the light flashed dimmer. Almost like one of the capacitors is dead and leaving it on for a few minutes is charging it.
    I've had issues like this on a computer power supply, but want to make sure it won't blow up if I leave it plugged in for an hour to see if it eventually turns on.

    It probably won't blow up but it might smolder/smoke or spontaneously generate an assistant electrician....

    You might want to give a call to Used lighting dot com and inquire about replacement PSUs....

    So got an email about my inquiry from the company I originally purchased these VL2000s from and they said the power cable can sometimes be weird DEPENDING ON THE FIXTURE'S ORIENTATION.
    Caps part is what caught my eye.
    Is there a sensor for direction of installation that limits power? My understanding with these is they can be operated in any orientation, and if nothing else, sitting flat on a stage seems normal.

    My direct experience with VL2000s is putting them in road cases... but I think the vendor is saying "the F*&#(!#@ power cable gets loose in certain positions."

    I take it to mean that the power cable has some loose connections and may not make contact when oriented a certain way...

    Edit: Posted concurrently with the above. Look in to the cable - both the connector and where it enters the fixture (on both sides of the strain relief/panel-mount connector if applicable). If it's dickey (technical term), you'll want to get that sorted as not only is it an annoyance, but a fire and shock hazard.

    Took off the covers last night and all the power cables seem normal. Ground is bolted down and +- connect to the transformer, then to the power switch.
    Even removed the power switch because the cable comes through the body underneath the switch, so I wanted to check that there isn't some twist or sever.
    The weird thing about this light is the PWR light flashes on the front panel once every 5 seconds and you can hear some electrical transformery noise. And when I powered it up with the cover off, you can see the fan do a wiggle concurrently with the PWR light flash.
    My feeling is that initial transformer (not the power supply) isn't happy.
    I guess I'll start forking together some parts from a working model to pinpoint the problem unless anyone else has an idea.
