I have a studio command 700 that will power on and self test but has no response to dmx. I have opened up the fixture and replaced a fuse on the power supply side but I dont see any fuses blown on the logic card. I have tested the cable that goes from the xlr connector to the logic card and it is good. I am just wondering where to go from here? Is there a bad driver chip if so how can I test it? Is there a fuse on the dmx input that I am not seeing?
