Hey guys i've got a DL3 that the actual fixture has frozen up on me. The Media server boots up and is visible on CMA but the fixture (P/T, iris, zoom, etc.) acts like the power is off.
Check the 40DC power supply, the fuse could be blown. you can look at either the box card or the head card and see if there are any LED's that are on, on the card if not it could be the power supply fuse or it could be the tiny little fuse on the head/box card.
