Step 5: Remove the Lens and Motor Assembly by 
pulling forward and to the left in order to 
clear the Projector chassis with the Motor 
Assembly.
Step 6: Install new Lens Assembly in reverse 
order. Make sure to route the wire harness 
(Item 4) in original position and away from 
moving lens stages and Motor Assembly to 
prevent unexpected disconnect or lens 
damage.--See Figure 6 Below--

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
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 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
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.
· Incorrect phone cord
· The Controller is on the wrong
source.
· The 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
Projectors 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-4000ci.
· Only NTSC/PAL can be input
to the Component input.
Progressive scan must go into
RGB/Component.
· Turn down the CONTRAST
level on the 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.
PROBLEM POSSIBLE CAUSE SOLUTION 
						

							The image appears too
washed out, or the darkest
areas of the image appear too
bright.
The colors of the image
appear abnormal
The image appears keystoned
(trapezoidal).
The Projector will not turn on,
and the power LED on the
front of the Controller is
blinking red.
The Projector will not turn
back on after it was powered-
down, or the image disap-
pears during operation.· Brightness is set too high.
· The DVD player may be set
for too high of a brightness
level.
· The Red, Green and/or Blue
outputs of the Controller or
inputs to the Projector are
reversed.
· The Pr and Pb inputs on the
Component input on the
Controller are reversed
· The Projector has been
mounted too high or too low in
respect to its vertical 
offset.
· The Controller may have
locked-up. 
· The Projector will not turn on
for two minutes after power-
down to protect its bulb.
· The bulb has failed· Turn down the BRIGHTNESS
level on the Controller. If possi-
ble, use a PLUGE pattern to set
the brightness level properly.
· Set the DVD player for a nomi-
nal output (no boost or gain).
· Check the cable connections
on the back of the Controller or
on the Projector.
· Adjust Keystone, see page 29. 
· Unplug the Controller for 2
minutes; plug it back in a re-try.
· Perform a system reset on the
Controller (see page 30), and
then re-try.
· Wait two minutes until the LED
on the front of the Controller
turns red.
