General Troubleshooting Suggestions

The following table shows general troubleshooting suggestions:

Problem	Solution
Won’t power on	• Check the fuse (page 216).
	• Verify fixture is plugged in to an appropriately-rated power source (power
	ratings are shown on page 292).
	• Check power cord wiring (page page 292).
During certain movements	• If you have loosened or tightened anything in the pan and tilt assemblies,
the fixture motion slows,	the stepper motors may be out of alignment. Recalibrate pan and tilt motors
missteps or loses position	by selecting Calibrate Motors button in the Test_Home menu screen.
Powers on but no image	• Is the mechanical iris closed? If so, check the setting for the Dimmer
	parameter, (see Dimmer on page 179.)
	• Did you recently change inputs? About 10 seconds are required for an input
	change to take effect. However, you might have selected an invalid input
	using projector controls.
	Try setting the projector back its defaults, (see Reset Screen on page 35.
	Or use DMX to exit the projector menu system (see Projector Control on
	page 181).
	• Make sure a video input is physically attached to the input you selected, and
	that the video feed is active.
