Im having a lighting problem. i have a grand ma. one day i came in and turned on the board and just about every light in my rig was going nuts. All the faders were down. I hadnt even done anything yet. I have 14 vl3000's, 4 vl3500's a bunch of pars and likos, and 26 color blast 12's. But like i said i turned on the board and you could hear the vl's strobing, the color blasts were changing colors and flickering, and pars and likos were blinking. This lasts for about ten minutes, then it stops. i also have a ghosting problem with one set of color blasts. its a set of four. They are on a pds-150 power supply. They will not stop flickering when the board is on. Ive changed the dmx cable, ive moved the power from one input to another and it still does it. what could be the problem?
