Powers on but no image • Is the mechanical iris closed? If so, check the setting for the Dimmer
parameter, (see Dimmer on page 119.)
• 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 33.
Or use DMX to exit the projector menu system (see Projector Control on
page 121).
• Make sure a video input is physically attached to the input you selected, and
that the video feed is active.
Image is blurry, out of focus,
or colors are unnatural
• Check the Fixture filters (see page 151 ).
• Is the DL.2 mounted less than 1.4 meters to an object? If so, move the DL.2
farther away to enable it to focus properly.
• Make sure the DL.2 is not operating near fog machines, hazers, or mineral
oil hazers (see Fog Machine Warning on page 8).
• Clean the front window (see Cleaning or Replacing the Front Window
on page 154).
• Check the lamp (see the projector manual shipped with the DL.2).
• 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 121.)
The LCD Menu display is off • If the Blue LED is off, the Computer isn’t receiving power. Press and hold the
Top and Bottom Tab select buttons to restart computer, (see Menu Panel
Components on page 19.)
• If the screen is not backlit, press the LCD power button, (see LCD Display
Adjustment Buttons on page 20.)
• Check the Video In Video Out adapter on the video card (middle plug)
connection.
• Check that the connectors for the composite video cable at the LCD Screen
and the Video card are seated securely.
Fixture behaves erratically or
won’t respond to DMX control
• Verify that the last unit on the DMX link is properly terminated, (see Setting
up a Standard DMX Link on page 10.
• To control the DL.2 with DMX, you must first enable DMX through the menu
System (see DMX_Control Screen on page 25) or the CMA (see Viewing
and Editing Fixture Configuration on page 143.
• If you’re using DMX to control the projector using its native menu system,
make sure you send a safe command after each button command;
otherwise, it’s analogous to pressing a button on the projector menu system
and not releasing it (see page Projector Control on page 121).
