Okay, something tells me this is a controller problem. Check your light board to make sure it is set up perfectly. Check each step of the
system: 1st make sure everything is patched correctly, then make sure that you are using the correct method to turn everything on, next check every
plug to make sure it's all the way in, then check to make sure no wires are nicked.
Another course of action would be to try and isolate the problem to figure out what it is. Try a different light on the same set up to see if it's the light. If the other light works, the
PAR is your problem. If not, the controller or
dimmer is. Next, try the same set up using a different
dimmer. If this works, the
dimmer is your problem. If not, the controller or one of the connections is your problem. Continue with this same course of logic to eliminate all other components of the equation. Eventually, you should be able to find your problem. This sounds tricky, but if you have maybe 3 people then you can get it done in a few hours. Not easy, but far better than not being able to use lights.
