Problem Solution
The fixture won’t power on
1. Verify fixture is plugged in to an appropriately-rated power
source (power ratings are shown on page 1-4).
2. Verify the power switch is in the ON position.
3. Check the fuse (page 5-4).
4. Check power cord wiring (page page 2-1).
The fixture powers on but
no image
1. Make sure a video input is physically attached to the input you
selected, and that the video feed is active.
2. Is the dimming iris closed? (If so, check the setting for DMX
channel 10—Control—which usually shuts the dimming iris. See
page 4-4.)
3. 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.
4. Set the projector back to its default settings as shown on
page 3-9. Or use the DMX protocol to exit the projector menu
system (see page 4-4).
Image is blurry, out of focus,
or colors are unnatural
1. Check the housing filter (see page 5-2).
2. Is the DL.1 mounted less than 1.4 meters to an object? If so,
move the DL.1 farther away to enable it to focus properly.
3. Make sure the DL.1 is not operating near fog machines, hazers,
or mineral oil hazers (see page 2-4).
4. Clean the front window (see page 5-5).
5. Check the lamp (see the projector manual shipped with the
DL.1).
6. If you’re using the projector’s on-screen programming system,
you can override zoom and focus using the menu system (see
page 3-10).
Projector behaves
erratically or won’t respond
to DMX control
1. To control the internal projector with the DMX protocol, you must
first enable DMX (see page 3-10).
2. 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 4-4).
