5. REMOVE THE LAMP MODULE 
Firmly grasp the lamp by its housing only and pull it straight out (lamp slides 
along guides) until it is free. See Figure 4.4. Discard the lamp using safe 
disposal/recycling practices.
 
 
 
6. INSERT THE NEW LAMP MODULE 
Align the new lamp with the top and bottom guides on the left side of the lamp 
compartment (see Figure 4.5). Slide the lamp all the way in – a slightly harder 
push may be required right at the end to ensure it’s fully seated into the terminal 
block.  
 
NOTE: The lamp module must make full contact
 with the terminal block. The 
projector will not power up again if the lamp is not fully connected to the terminal 
block. 
 
       Figure 4.5. Insert New Lamp Module
 
 
 WARNING  
Improper installation could cause a serious 
meltdown inside the projector. 
7. LOCK IN THE NEW LAMP MODULE 
Pull out and turn the lamp lock lever (turned up in Step 4) ¼ turn clockwise to 
“lock” the lamp in place.

							  Section 4: Maintenance 
020-100001-01 Rev. 01 (04/07)  4-9. 
 
NOTE: If you can’t turn the lamp lock into position, it is likely the lamp is not 
fully inserted. In this case, partially remove the lamp and try pushing it back in 
again. Then, try switching the lock lever to the “lock” position. 
 
8. REPLACE THE LAMP DOOR 
Replace the lamp door and secure it with the two (2) screws removed in Step 2. 
IMPORTANT: The lamp module is calibrated for maximum performance and 
brightness in this projector. Do not attempt to re-align or adjust the lamp module. 
 
9. RECORD THE SERIAL NUMBER OF THE NEW LAMP  
• Plug in the projector and power it up. 
• In the Lamp menu, select “Change Lamp”. 
• In the Lamp S/N text box, enter the serial number. 
• Press to record the number and to reset the lamp timer. The timer will now 
begin to log time for the new lamp. 
 
 
 
                  
IMPORTANT: If you neglect to enter a serial number, the lamp timer will not 
reset to “0” and will therefore be inaccurate. The lamp life limit may then expire 
prematurely.

The two filters located at the front and left side of the projector should be replaced 
whenever the lamp is replaced. If you are working in an extremely dusty 
environment you may want to replace the filters sooner. Use the filters provided in 
the Christie approved Lamp and Filter Kit for your specific projector model. 
1. TURN OFF THE PROJECTOR, COOL and UNPLUG 
Before removing or installing a filter, turn off the projector and allow it to cool for 
five minutes before unplugging. 
2. REMOVE FILTER ACCESS 
PANELS 
Loosen the captive screw(s) on the filter 
access panels using a #2 Phillips 
screwdriver. (Front access panel located 
to the left of the lens – one screw. Left 
side access panel – three screws. See 
Figure 4.6.) 
 
3. REPLACE FILTERS 
Pull the old filters out of the projector and discard. Do not reuse filters. Insert the 
new filters with the wired side in. See Figure 4.7.

Rotate the lens counter-clockwise until 
the tabs are free from the lens retainer 
ring. See Figure 4.10A. 
NOTE: The connector slide assembly 
allows the connector to move as the 
lens is rotated. 
Pull lens out 
Lens connectors will disconnect when 
you pull the lens straight out from the 
projector. See Figure 4.10B. 
 
Insert new lens. 
NOTE: Remove small rear cap! Keep front cap on. 
• Electrical connector: Line up male connector on the lens with the female 
connector on the connector slide assembly. 
• Insert lens: Align the tabs on the lens plate lock with the slots in the lens 
retainer ring. Push the lens in approximately ½ inch. 
• Rotate the lens: Rotate the lens clockwise until the tabs are tightly secured and 
the lens release button CLICK. 
• Secure lock-down screws 
(optional): For added stability, 
secure the adjustment screws 
provided on the lens-retaining ring 
(see Figure 4.11). If you have 
installed a large zoom lens, one or 
more of the screws may be 
inaccessible—simply tighten those 
that are accessible (Figure 4.12). 
NOTE: Recommended for heaviest 
lenses such as 0.73:1 and 1.2:1. 
Power Up  
Remove the lens cap and power up the 
projector. 
Reposition the Projector for New 
Lens 
Reposition the projector closer or further 
from the screen as necessary for the screen 
and the new lens type – refer to lens 
descriptions in Section 2, Section 6 and

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”. 
 
 
The projector is on but there’s no display... 
1. Was a lens cover accidentally left on? Remove lens cover. 
2. Ensure the shutter is OPEN. 
3. Is the lamp ignited? Check for interlock problems such as an open lamp door OR 
check for light spillage out the back. 
4. Is the correct input selected? Check cable connections. 
5. Check if menus appear on screen. 
6. Can you access test patterns? 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. 
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. 
Image appears “squeezed” or vertically stretched into center of screen 
1. Check your Resizing selection. 
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 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 non-video) may need a different sync tip clamp location.

5-2 020-100001-01 Rev. 01 (04/07)   
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. 
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. 
The display appears compressed … 
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. 
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. It’s 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. Try Auto Setup. 
2. The color, tint, color space, color temperature and/or other settings may require 
adjustment. 
3. Ensure signal connections are correct. 
4. Ensure the proper channel for this source is being used. 
Values in Color Saturation slide bars vary over time… 
1. Once defined, Color Saturation slide bar 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. Ensure 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.

020-100001-01 Rev. 01 (04/07)  5-3. 
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. Ensure 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 (e.g. “DMD over critical temp limit”), 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. 
2. Replace the lamp. 
1. Ensure the “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. Ensure the Ethernet settings are valid for your site—all network devices should 
have the same subnet mask and unique IP addresses. 
2. Ensure any address changes have been saved, and re-boot to implement.  
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.
