I have quite a problem. Two of our lights, a 36 degree Source Four and an 8 inch Fresnel, are not working. The lamps are fine, but there isn't any power going to it. I'm almost positive it's a bad power input. One of our power inputs had a neutral plug fall out. Is there any way I can replace it? Or am I going to need a new box? That however, does not explain why both aren't working. Only the Source Four. At this point I'm still trying to figure out what's wrong with the Fresnel. Any suggestions would be great.
