Case
Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do not use liquid or
aerosol cleaners.
4.3 Replacing Keypad Batteries
The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably alkaline). To install
new batteries, open the battery compartment at the back side of the keypad by pulling on the
raised portion of the cover as shown below.
Replacing Keypad Batteries
Remove the old batteries and properly discard. Wait a minute or two and place the new batteries
in the compartment, orienting the positive/negative of each battery according to the labels in the
compartment. When batteries are in place, replace the cover by inserting its bottom edge first and
snapping the top into place. Do not force.
NOTE: Always wait a minute or two when replacing batteries so that the internal electronics dis-
charge and can recognize the change.
NOTE: For this procedure you will need a VX-4c/VX-6c Lamp and Filter Replacement Kit from
Runco.
The high brightness of your projector is provided by a 700 watt Xenon lamp permanently mount-
ed inside its own protective housing. When the bulb approaches 1000 hours of usage, this lamp
assembly should be replaced.
How Old is The Lamp?
The number of hours logged on the current lamp appears both in the Lamp Adjustsubmenu
(accessed through the Advancedmenu) and the Informationmenu. In the Information menu, do
not confuse “Xenon Lamp Hours” with “Projector Hours”, which indicates the number of hours
logged during the ‘rental period’, in a situation where the VX-4c/VX-6c is to be rented for vari-
ous functions. In a permanent install, this would be of no consequence.
NOTE: As the lamp nears its limit (as set in Lamp Limit), a message can appear on screen to
warn that the lamp needs to be replaced. To make sure that this warning appears, enter a check-
mark in the Lamp Message checkbox located in the Lamp Adjust submenu.

4.5   Troubleshooting
If the projector appears not to be operating properly, note the symptoms present and use the fol-
lowing guide to assist you. If you cannot resolve the problems yourself, contact your Runco deal-
er for assistance.
NOTE: Always check the LCD status window at the rear of the projector for initial information
about a problem.
SymptomThe projector will not turn on when          is pressed...
CAUSE / REMEDY:
1. Make sure to hold         for approximately one second. Or press  quickly and release, and fol-
low with        .
2. Do both LEDs come on at the rear of the projector? Check that the power cord is properly con-
nected at the wall outlet (100-240 VAC, 50-60 Hz nominal) and that you are using the original
high-current 13A cable provided.
3. Does the green “Status” LED flash with each key press? If not, the projector is not receiving
the keypad’s IR signals. Ensure the keypad is directed at either the front or rear of the projector,
or at the screen. Also make sure that these paths are not blocked. Try the built-in keypad.
4. The batteries in the IR remote keypad may be weak. Refer to page 2-17, Replacing Keypad
Batteriesfor instructions.
5. The IR keypad may have been disabled by a change in protocol. See 2.12, Keypad Protocols
and Conversionand 3.7, Adjusting System Parameters and Advanced Controls.
6. Use the         key on the built-in keypad to turn the projector on.
SymptomThe projector is on but I can’t see display of source input...
CAUSE / REMEDY:
1. Was the lens cover accidentally left on? Remove lens cover.
2. Is the shutter closed? Is the projector in standby? Press          to clear.
3. Is an active source connected properly? Check the cable connections. And is the correct source
selected? Press         ,        ,        , or        to select. See 2.10, Source Connectionsand 3.13, Using
Inputs and Channelsfor details.
4. Are there test patterns or menus present? If so, check your source connections again.
5. The room lighting may be too bright. Lower the intensity of the room lighting. Reduce light
reflections as much as possible.
6. Increase contrast and/or brightness of image.
7. The projector may be too far from the screen. Move the projector closer.
8. Is the “Status” LED flashing a pattern of yellow and red lights while the “Power” LED is steady
red? This indicates an internal system error that may prevent the projector from operating. If the
problem persists contact a qualified Runco service technician.

SymptomThe projector does not respond to the infrared remote keypad...
CAUSE / REMEDY:
1. Does the built-in keypad work? If so, check that the keypads are enabled.
2. Does the green “Status” LED flash each time a key is pressed? If not, the projector is not
receiving the keypad’s IR signals. Ensure the keypad is directed to either the front or rear of the
projector, or towards the screen.
3. The viewing path between the IR keypad and the projector (or screen) may be blocked. Ensure
there is a clear line-of-sight between the keypad and the projector (or screen).
4. The batteries in the IR remote keypad may be weak. Refer to page 2-17, Replacing Keypad
Batteries for instructions on how to replace the batteries.
5. There may be unusual lighting conditions in the room affecting IR keypad operation.
Determine if such conditions exist and correct.
6. The IR keypad may have been disabled for use with this projector(s). Press     to enable broad-
casting to all projectors. See 2.12, Keypad Protocols and Conversion and 3.7, Adjusting and
Checking System Parameters for additional information.
SymptomThe power is on but the lamp is not...
CAUSE / REMEDY:
1. Does the LCD status window say “warming up”?
2. The projector probably became overheated (there is likely an error code flashing and a mes-
sage in the LCD status window). Allow to cool and make sure that nothing blocks projector vents.
Do not operate in environments warmer than 35°C (95°F).
3. The lamp may have reached the end of its life. Check the “Lamp Hours” via RS-232 request
‘lph?’.
SymptomThe display is jittery or unstable...
CAUSE / REMEDY:
1. If the display is jittery or if it disappears and reappears erratically, check that the source is prop-
erly connected and that its signal is of adequate quality for detection. For example, it the projec-
tor scans the default input  for a signal to display, and a poor quality or improperly connected
source is connected, the projector will briefly and repeatedly attempt to display an image. If no
source is connected, the “No signal present” error message appears over a blank display. Correct
the source connection.
2. The horizontal or vertical scan frequency of the input signal may be out of range of the pro-
jector. Refer to page 5-1, Specifications for scan frequency ranges.
3. The sync signal may be inadequate. Correct the source problem.
4. The input signal type may conflict with the input module. Install/use the correct module for the
source.
5. Pixel tracking, phase, filter, etc. may need more adjustment.
SymptomThe display is faint...
CAUSE / REMEDY:
1. Check Input Levels option-turn auto to “off”, then “on” again.
2. Brightness and/or contrast may be set too low. Adjust as necessary.
3. Gamma may be set too low. Recommended setting for most signals is 2.2.
4. The projection room may be too bright. Lower the intensity of projection room lighting and
reduce light reflections as much as possible.
5. The projector may be too far from the screen. Move the projector closer.

6. The location of the audience with respect to the screen may not be ideal. Make sure the audi-
ence is within the viewing angle set by the projector and screen position, and the screen type.
7. The source may be double terminated. Ensure the source is terminated only once.
8. The source (if non-video) may need sync tip clamping. Enter a check in the Clamp Tip box
found in the Input Levelssubmenu.
SymptomThe display is reversed and/or upside-down…
CAUSE / REMEDY:
1. The projectors image orientation is not set correctly for the current installation. Refer to2.6,
Operating Orientation to set the projectors image orientation to match your installation. 
SymptomThe upper portion of the display is waving, tearing or jittering…
CAUSE / REMEDY:
1. This can sometimes occur with video or VCR sources. If you are using a VCR, make sure that
the VCR option is checked (in Advancedmenu).
SymptomPortions of the display are cut off or wrap to the opposite edge…
CAUSE / REMEDY:
1. Reduce top, bottom, left or right blanking from within theScaling Parametersmenu. Check
size and position adjustments.
2. Resizing may need adjustment. Adjust until entire image is visible and centered.
SymptomThe display appears compressed or stretched…
CAUSE / REMEDY:
1. The frequency of the pixel sampling clock is incorrect for the current source.
2. TheScaling Parametersoptions may be adjusted poorly for the incoming source signal. 
See 3.6, Adjusting the Image.
SymptomDisplay quality appears to drift from good to bad, bad to good…
CAUSE / REMEDY:
1. The operating temperature of the projector may be fluctuating. Watch that the projector is not
located too close to heating/air conditioning vents.
2. The source input signal may be of low quality.
3. The horizontal or vertical frequency of the input may have changed at the source end.
SymptomThe display has suddenly frozen, or an unknown menu has appeared…
CAUSE / REMEDY:
1. You may have accidentally entered a special engineering code using the          key in combi-
nation with certain numbers, or you may have selected the Freeze Image option. Press         as
necessary to cancel the function and return to presentation level.
2. If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or
ground input has interrupted the projectors ability to lock on to a signal. Turn the projector off,
wait for the lamp fans to stop, and unplug. Plug in again and power up as usual.
SymptomThe display is not sharp or clean…
CAUSE / REMEDY:
1. More display adjustment may be required-focus, brightness, contrast, pixel tracking, pixel
phase, and detail.
2. If you are using a BNC T-connector, try using a distribution amplifier to boost signal levels.
3. Is the video input signal properly terminated? Set in OSD Settings menu.
4. The screen size may be too large. As screen size increases, magnification increases, reducing
brightness and clarity. See lens specifications in Section 5.
5. The source input signal may be of low quality. Try another source.

SymptomColors in the display are inaccurate…
CAUSE / REMEDY:
1. The color, tint, gamma, color space and/or color temperature settings may require adjustment.
Review all settings, and refer to 3.6, Adjusting the Image and 3.7, Adjusting System Parameters
and Advanced Controls.
SymptomThe display is not rectangular…
CAUSE / REMEDY:
1. Check leveling of the projector. If necessary, try relocating the projector or screen so that the
lens surface and screen are approximately parallel
2. Is the vertical offset set correctly? Adjust as necessary using the vertical offset knob on the
front of the projector.
3. The Vertical Stretch option may need adjustment. Also check pixel tracking.
SymptomThe display is noisy…
CAUSE / REMEDY:
1. Display adjustment may be required. Adjust pixel tracking, phase and filter.
2. The video input may not be terminated. Make sure the video input is terminated (75 Ω). If it
is the last connection in a loop-through chain, the video input should be terminated at thelast
projector only.
3. The signal cables carrying the input signal may be of poor quality. Use only good quality sig-
nal cables.
4. The distance between the input source device and the projector may be too great. If the dis-
tance between the input source device and the projector is greater than 25 feet, signal amplifica-
tion/conditioning may be required.
5. The input signal may be of poor quality.
6. If the source is a VCR or off-air broadcast, detail may be set too high. Keep near 4 for most
sources.

* ANSI Lumen Specification:
This is the typical projector luminosity (brightness) specification found in most sales literature. This measurement is
included in RUNCO literature to allow for direct comparison with other manufacturer’s projectors. These measurements
can be taken at 9,000°to 13,000°Kelvin to get expected performance data when the projector is used in professional,
commercial, and industrial displays.
CSMS Home Theater Calibration ANSI Lumen Specification:
These measurements are taken from the projector as set up in a home theater environment. The projector is calibrated
to ISF specifications including setting the color temperature to 6500°K, the standard for reproducing video.
CSMS Home Theater Calibration foot-Lambert (fL) Specification:
This is the unit of measurement used in commercial movie theaters to express image brightness. The Society of Motion
Picture and Television Engineers (SMPTE) specifies 16 fL as the target image brightness for film-based projectors using
an open gate (without film in the projector). More importantly, today SMPTE specifies 12 fL as the target image bright-
ness in Digital Cinema theaters using DLP™ technology. The foot-Lambert is dependant on screen size, screen gain,
and projector light output.
All measurements are made at RUNCO to ANSI/NAPM IT7.228-1997 specifications using the Photo Research PR-650
Spectra Colorimeter and Minolta LS-100 Luminance Meter, Video Essentials test DVD, and a Da-Lite 1.5 gain, 100-inch
wide screen. The projector is calibrated to a color temperature of 6500°Kelvin and has a minimum of 150 hours of
usage.
