Maintenance and Troubleshooting
230 DL.3 Digital Light User Manual
Image is blurry, out of focus,
or colors are unnatural
• Check the Fixture filters (see page 17-217).
• Is the DL.3 mounted less than 1.4 meters to an object? If so, move the DL.3
farther away to enable it to focus properly.
• Make sure the DL.3 is not operating near fog machines, hazers, or mineral
oil hazers (see
See “Fog Machine Warning” on page 8.)
• Clean the front window (see “Cleaning or Replacing the Front Window” on
page 17-223).
• Check the lamp (see the projector manual shipped with the DL.3).
• 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 14-181.)
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 3-21.)
• If the screen is not backlit, press the LCD power button, (see “LCD Display
Adjustment Buttons” on page 3-22.)
• 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 2-10.
• To control the DL.3 with DMX, you must first enable DMX through the menu
System (see
“DMX_Control Screen” on page 3-27) or the CMA (see “DL.3
and DL.2 Media Server Configuration Options” on page 16-208).
• 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 14-181).
