I just picked up 5 of these Design Spot 250 fixtures and 3 work great but I'm having issues with 2 of them. One has a really jerky and slow pan in both self test and DMX - it seems to rotate fine when starting up and homing - sensor? driver board? Motor? How do you get to the motor to replace it? In DMX it takes forever to rotate and then doesn't seem to want to rotate back the other way.
The other fixture isn't showing DMX although it passes DMX thru to the next fixture - board? wiring harness?
Is there a place where I could find a service manual or exploded diagrams for these?
Thanks in advance for any suggestions!
