If the projector does not appear to be operating properly, note the symptoms present 
and use the following guide to assist you. If you cannot resolve the problems 
yourself, contact your dealer for assistance. 
NOTE: A qualified service technician
 is required when opening the projector to 
diagnose any “probable cause”. 
 
 
 
Blank screen, no display of image… 
1.  Confirm all power connections are still OK. 
2.  Make sure the lens cap has been removed. 
3.  Make sure the shutter is OPEN. 
4.  Make sure there is not a full black test pattern selected for display—press 
Menu 
 to access test patterns, then cycle patterns with  keys. 
5.  Is the input selected? Check connections. 
Blacklevels seem too high 
Reduce Brightness setting. 
Image appears “squeezed” or vertically stretched into center of screen 
1.  Check your Resizing selection. 
2.  The anamorphic lens (optional) may be needed for this source. 
The projector is on but there’s no display... 
1.  Was a lens cover accidentally left on? Remove lens cover. 
2.  Make sure the shutter is OPEN. 
3.  Is the lamp ignited? Check for interlock problems such as an open lamp door. 
4.  Is the correct input selected? 
5.  Is the source connected properly? Check the cable connections and make sure the 
correct source is selected. 
6.  Is AC power connected?

The display is jittery or unstable… 
1.  If the display is jittery or blinking erratically, ensure that the source is properly 
connected and of adequate quality for detection. With a poor quality or 
improperly connected source, the projector will repeatedly attempt to display an 
image, however briefly. 
2.  The horizontal or vertical scan frequency of the input signal may be out of range 
for the projector. Refer to Section 6, Specifications for scan frequency ranges. 
3.  The sync signal may be inadequate. Correct the source problem. 
The display is faint… 
1.  Brightness and/or contrast may be set very low.  
2.  The source may be double terminated. Ensure the source is terminated only once. 
3.  The source (if non-video) may need a different sync tip clamp location. 
The upper portion of the display is waving, tearing or jittering… 
1.  This can sometimes occur with video or VCR sources. Check your source. 
Portions of the display are cut off or wrap to the opposite edge… 
1.  Resizing and/or blanking may need adjustment. 
The display appears compressed (vertically stretched)… 
1.  The frequency of the pixel sampling clock is incorrect for the current source. 
2.  Resizing, vertical stretch and positioning options may be improperly adjusted for 
the incoming source signal. 
3.  You may need an anamorphic lens for sources that have been supplied in a re-
sized and vertically stretched format. 
Data is cropped from edges 
1.  Check settings for Blanking. 
2.  If incoming data is still missing from the image, reduce the image size to within 
the display area available in the projector.  
Display quality appears to drift from good to bad, bad to good… 
1.  The source input signal may be of low quality. 
2.  The H or V frequency of the input may have changed at the source end. 
The display has suddenly frozen… 
1.  If the screen blacks out inexplicably, it is possible that excessive voltage noise on 
the AC or ground input has interrupted the projector’s ability to lock on to a 
signal. Power down the projector and disconnect from AC. Then plug in again 
and power up as usual. 
Colors in the display are inaccurate… 
1.  The color, tint, color space, color temperature and/or other settings may require 
adjustment. 
2.  Make sure you are using the proper channel for this source.   Symptom '

Values in Color Saturation slidebars vary over time 
1. Once defined, Color Saturation slidebar values fluctuate over time and will likely 
be different upon subsequent visits to this menu. This is normal and should be 
ignored, as these changes do not redefine the x/y coordinates or color gamut. 
The display is not rectangular… 
1.  Check leveling of the projector. Make sure that the lens surface and screen are 
as parallel to each other as possible. 
2.  Is the vertical offset correct? Adjust as necessary using the vertical offset 
knob. 
The display is “noisy”… 
1.  Display adjustment at your input source may be required. Adjust pixel tracking, 
phase and filter. Noise is particularly common on YPbPr signals from a DVD 
player. (If using a PC source, adjust using a high-frequency test pattern with one 
pixel on/off throughout.) 
2.  The video input may not be terminated. Make sure the video input is terminated 
(75Ω). If it is the last connection in a loop-through chain, the video input should 
be terminated at the last source input only. 
3.  The input signal and/or signal cables carrying the input signal may be of poor 
quality. 
4.  If the distance between the input source device and the projector is greater than 
25 feet, signal amplification/conditioning may be required. 
5.  If the source is a VCR or off-air broadcast, detail may be set too high. 
 
1.  If the lamp won’t ignite, there may be an interlock failure such as an open lamp 
door, or failed lamp fan. An error code will display on the status LED display 
located on the built in keypad. 
2.  If a temperature is too high (“DMD over critical temp limit”, e.g.), the lamp will 
not ignite until the temperature is low enough. Cool the projector and try again. 
3.  For suspected communication failures, power-down the projector and try again.  
4.  If the lamp does not ignite after a second and third try, replace the lamp. 
 
1.  Try increasing the lamp power. 
2.  The DMDs may be overheated. 
3.  Replace the lamp. 
1.  Increase lamp power, if possible. 
 
1.  Make sure “Intensity” is selected in the Lamp menu. Other lamp modes disable 
LiteLOC . 
2.  If the lamp power has increased to its maximum in order to maintain a 
LiteLOC   setting, LiteLOC is automatically terminated. If the values shown 
in the Lamp menu indicate that the lamp power has reached this “over-drive” 
state, either reduce your LiteLOC setting or install a new lamp.

1.  Make sure the Ethernet settings are valid for your site—all network devices should 
have the same subnet mask and unique IP addresses. 
2.  Make sure the projector is connected to a network before you attempt to change its 
IP address, and always cycle power (off-on) to implement the new IP address. 
3.  Make sure to save any address change, and re-boot to implement.  
4.  If you still have trouble establishing communications with a projector added to an 
existing Ethernet network, the projector’s IP address is likely in conflict with 
another address already in use. Contact your network administrator.
