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.
The projector does not turn on
after initial installation. The
Power LED on the front of the
PFP Controller stays yellow
after the power button is
pressed.
The projector and PFP
Controller are both on, but
there is no video image on-
screen.
The projector is producing a
'split screen' or an otherwise
scrambled image.
The image appears too bright,
and there is a loss of definition
in the brightest areas of the
image.
· The RJ-11 (ComLink) cable is
not connected between the PFP
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 and see if
it is illuminated.
· The PFP Controller is on the
wrong source.
· The PFP Controller is on the
correct source, but the source
itself is off.
· A progressive scan DVD is
plugged into Component input
rather than the RGB/Component
input.
· Contrast is set too high.
· The DVD player is set for a
high-level output.
· The video signal has not been
terminated properly somewhere
in the system.
· Use a standard RJ-11
phone-type cord. Ensure it is
firmly plugged into both the
Controller and the Projector.
· Ensure there is good conti-
nuity in the RJ-11 cable.
· Verify that the AC outlet is
active, or that the Projector is
plugged in.
· 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 rec-
ommended that all sources be
turned on first BEFORE the
VX-1000c.
· Only NTSC/PAL can be input
to the Component input.
Progressive scan must go into
RGB/Component.
· Turn down the CONTRAST
level on the PFP Controller.
Mid-range is 127; it is recom-
mended to keep it below 140
to prevent this problem.
· Set the DVD player for a
nominal output (no boost or
gain).
· Ensure all video signals are
terminated in 75 Ohms.
