6 Troubleshooting
If the projector is not operating properly, note the symptoms and use this section as a guide to resolve the 
problem. If the problem cannot be resolved, contact your dealer for assistance. 
NOTE: A Christie accredited 
service technician is required when opening an enclosure to diagnose any “probable cause”. 
6.1 Power
6.1.1 Projector Does Not Power ON
1.Ensure projector is plugged in? Check power switch above power cord is in the ON position.
2.Check that the Status LEDs are ON. While the projector is busy initializing, the LEDs should be 
cycling. When finished initializing, the Power and Shutter LEDs (the two on the right) should be on. 
3.Check the LCD. While the projector is busy initializing, the display should show “Please wait”. When 
finished initializing, the display should show “Standby mode”.
4. Check the LCD for any warnings or errors.
NOTE: A condition occurs on the first power on after a software upgrade, and is indicated by all the following:
• The Status LEDs are cycling green
• The LCD displays the warning Image Processor Upgrading
• The LED on the Image Processor card flashes green
• The Web page shows a warning that the Image processor card is upgrading.
When this occurs, the projector should not be AC power cycled and the Image Processor card should not be 
removed. This operation may take as long as 5 minutes to complete.
6.2 Lamp 
6.2.1 Lamp Does Not Ignite
1.Is there an interlock failure? Check the LCD for an error. The interlock failure could be an open lamp 
door or a failed lamp fan.
2. For suspected communication failures, power-down the projector and try again.
3. If the lamp does not ignite after step 2 above, then replace the lamp.

Advanced: Lamp menu. Try increasing lamp power. 
2. Check for an alarm condition on the LCD keypad display.
3. Replace the lamp.
6.2.3 Flicker, Shadows Or Dimness
1. Check lamp power through the remote keypad checking the Lamp menu or from the web user interface 
Advanced: Lamp menu. Try increasing lamp power. 
2. Replace the lamp.
6.3 LCD 
6.3.1 Blank Screen, No Menu Displaying  
1. Press any arrow key on the built-in keypad. The backlight on the LCD and the backlight for the built-in 
keypad should turn on. If the LCD is still blank, restart the projector.
6.4 Remote Keypad
6.4.1 Remote Keypad Does Not Seem to Work
1. Replace the batteries. 
2. Check if IR signals are received by the projector. Pressing any key on the remote control towards the front 
or rear sensor, the Status LED will blink, regardless if any command is executed. If the LED does not 
blink, restart the projector.
3. Ensure the remote keypad is enabled. If the projector is powered, using the built-in keypad, open the OSD 
menu and go to the Main Menu>Configuration>Communication submenu and check the check boxes for 
Front IR Enabled and Rear IR Enabled are checked. Enable them if they were disabled and try again.
4. Projector is busy. If the projector is busy in a warm-up mode or in a cool-down mode, the commands from 
the remote keypad may be ignored. Wait until the projector reaches a stable state (Power ON or Stand By) 
and try again.
5. Press the PROJ key on the remote keypad. If this brings up a pop-up box on the OSD, ensure that the 
check box is marked to enable the projector.

establishing communications with a projector added to an existing Ethernet network, the projector IP 
address is likely in conflict with another address already in use. Contact your network administrator.
2. Ensure Ethernet settings are valid for the site. All devices should have the same subnet mask yet unique IP 
addresses.
6.7 Displays
6.7.1 The projector is on but there is no display
1. Was a lens cover accidently left on? Remove lens cover.
2. On the LCD display, check that the shutter is open. This will also be indicated by the shutter LED being 
green.
3. Is the correct input selected. Check cable connections. 
4. Check if menus appear on the screen.
5. Can you access test pattern? Ensure a full black test pattern has not been selected for display, press Menu 
to access test patterns, then cycle patterns with keys. Check your source connections again.
6.7.2 Severe Motion Artifacts
1. Most likely there is a synchronization problem with reversed 3-2 pull-down in 60Hz-to-24Hz film-to-
digital conversion in your source. Correct at the source.
2. Adjust the Film Mode Detect control to correct the artifact. See 3.7 Image Settings Menu. VIDEO 
OPTIONS - Submenu, Film Mode Detect. If unsuccessful, return the Film Mode Detect control to Auto.

6.7.3 Image Appears ‘Squeezed’ or Vertically Stretched into Center of Screen
1. Run auto setup, pressing Auto button on the remote keypad.
2. Check your Resizing selection.
6.7.4 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 poor quality or improperly connected source, the projector will repeatedly 
attempt to display an image, however briefly.
2. The horizontal and vertical scan frequency of the input signal may be out of range for the projector. Refer 
to Section 7 Specifications for scan frequency ranges.
3. The sync signal may be inadequate. Correct the problem at the source.
6.7.5 The Display is Faint
1. Brightness and/or contrast and/or gamma may be set incorrectly.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if analog) may need a different sync tip clamp location. See 3.7 Image Settings Menu,  INPUT 
LEVELS - Submenu, Clamp Location. 
6.7.6 The Upper Portion of the Display is Waving, Tearing or Jittering
This can occur with video or VCR sources. Check your source.
6.7.7 Portions of the Display are Cut Off or Warped to the Opposite edge
Resizing may need adjustment. Adjust until entire image is visible and centered.
6.7.8 Display Appears Compressed (Vertically Stretched)
1. The frequency of the pixel sampling clock is incorrect for the current source.
2. Sizing and positioning options may be adjusted poorly for the incoming source signal.
3. Use an anamorphic lens for typical HDTV and anamorphic DVD sources that have been re-sized and 
vertically stretched, via 3rd-party software.
6.7.9 Data is Cropped from Edges
To display the missing material, reduce image size to fill the display area available in the projector, then stretch 
vertically to fill the screen from top to bottom. Add the anamorphic lens to regain image width.
6.7.10  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.

6.7.11 Display has Suddenly Frozen
If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or ground input has 
interrupted the projector ability to lock on to a signal. Power down the projector and disconnect from AC. Then 
plug in again and power up as usual.
6.7.12 Colors in the Display are Inaccurate
1. The color, tint, color space and/or color temperature settings may require adjustment at your input source. 
2. Try Auto Setup.
3. Ensure signal connections are correct.
4. Ensure the proper channel for this source is being used.
6.7.13 Display is Not Rectangular
1. Check leveling of the projector. Ensure the lens surface and screen are parallel to one another.
2. Is the vertical offset correct? Make the necessary adjustments to the vertical offset on the lens mount. 
6.7.14 Display is “Noisy”
1. Display adjustment at the input source may be required. Adjust pixel tracking, phase and filter. Noise is 
particularly common on YPbPr signals from a DVD player. 
2. Ensure the video input is terminated (75 ohms). 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 amplifica-
tion/conditioning may be required.
5. If the source is a VCR or off-air broadcast, detail may be set too high.
