Problem Solution
Won’t power on
• Check the fuse (
page 268
).
• Verify fixture is plugged in to an appropriately-rated power source (power
ratings are shown on ).
• Check power cord wiring
During certain movements
the fixture motion slows,
missteps or loses position
• If you have loosened or tightened anything in the pan and tilt assemblies,
the stepper motors may be out of alignment. Recalibrate pan and tilt motors
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 45.)
• 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 36.
Or use DMX to exit the projector menu system (see
Projector Control
on
page 47).
• Make sure a video input is physically attached to the input you selected, and
that the video feed is active.
Image appears “clipped off”
at the bottom
• This occurs when the iris plate is in the wrong position for the installed lens
and lens shift is not engaged. Standard, Accessory Wide Angle and
Accessory Ultra Long Throw lenses use one position. The Accessory Long
Throw lens use another (see
Adjusting the Iris Plate for the Accessory
Long Zoom lens
on page 269).
Image is blurry, out of focus,
or colors are unnatural
• Check the Fixture filters (see
page 265
).
• Is the DLHD mounted less than 1.4 meters to an object? If so, move the
DLHD farther away to enable it to focus properly.
• Make sure the DLHD is not operating near fog machines, hazers, or mineral
oil hazers (see )
• Clean the front window (see
Cleaning or Replacing the Front Window
on page 272).
• Check the lamp (see the projector manual shipped with the DLHD).
• If you’re using the projector’s on-screen programming system, you can
override zoom and focus using the menu system (see
Projector Control
on page 47.)
