Basic Troubleshooting Tips
The following is a basic troubleshooting guide that can assist you in resolving typical problems may
result in normal operation. If you have encountered problems that are not listed in this guide, please
contact your Runco dealer for assistance.
PROBLEM
The projector does not turn
on after initial installation.
The Power LED on the front
of the Controller stays
yellow after the power button
is pressed.
The projector and Controller
are both on, but there is no
video image on-screen.
The Brightness, Contrast,
Lens Zoom, Lens Shift, or
another adjustment runs
very slow or does not work
at all.
POSSIBLE CAUSE
· The RJ-11 (ComLink) cable
is not connected between the
Controller and Projector, or is
made improperly.
· The projector is not plugged
in, or its AC outlet is not
active. Look at its power LED
on the top panel.
· The Controller is on the
wrong source.
· The Controller is on the
correct source, but the source
itself is off.
· The Controller is on the
incorrect HD source for the
HD color space (Component
or RGB).
· The ComLink cable is not
connected between the
Projector and Controller or
not connected at all.

SOLUTION
· Use a standard RJ-11
phone-type cord. Ensure it
is firmly plugged into both
the Controller and the
projector.
· Ensure there is good con-
tinuity in the RJ-11 cable.
· Verify that the AC outlet is
active, or that the projector
is plugged in by turning on
the main power switch
located at the rear of the
unit.
· Press MENU on the
projector's remote, and look
to see which source is
active (the arrow will be
pointing to the active
source). Select the correct
source as appropriate.
· Turn on the source. It is
recommended that all
sources be turned on first
before the DLC-2000HD.
· Insert the ComLink cable
and make sure it is not
broken.
