Replacing the color sensor board
Remove the color sensor board and replace it with the upgraded board. A mechanical upgrade to the
housing is also required.
Caution! If not avoided, the following could result in minor or moderate injury.
• SHOCK HAZARD! Disconnect the product from AC before installing, moving, servicing, cleaning,
removing components, or opening any enclosure.
• Always connect the ground or earth first to reduce shock hazard.
• Observe all electrostatic precautions. Use a grounded wrist strap and insulated tools when
handling, servicing, or cleaning electronic assemblies.
1. Disconnect the projector from power.
Allow approximately 10 minutes for the projection system and mirror to cool-down before
servicing.
2. Raise the projector feet to create a clearance under the projector of approximately 12 cm or 4
¾ in.
Alternatively, tip the projector so it is resting on its side.
Before performing the upgrade procedure on a CP4325-RGB projector, consider inverting the
projector onto either its side or top-face for all service operations. If re-orienting the projector
is troublesome due to environmental or logistical constraints, all service operations can be
completed in typical landscape orientation, however there is increased difficulty in component
access, tool manipulation, and an increased risk in component damage if glass elements are
not handled very carefully.
3. Remove the bottom cover.
4. Loosen the two captive fasteners from the installed cover (A).
5. Remove the cover and set it aside.
6. Locate and loosen the four captive fasteners on the color sensor housing (B).

7. Gently pull the housing off the locating pins, allowing the assembly to hang by the harness.
8. Disconnect the harness from the PCB header and the harness retention clip.
The cover, housing, PCB, and captive fasteners can be discarded.
9. (CP4325-RGB only) Replace the coupling elbow mirror (on page 4). After replacing the
mirror, return to this procedure.
The fold mirror installed directly behind the color sensor housing must be exchanged for the
new version supplied in the upgrade kit. The surface of the legacy fold mirror is silver/
reflective on both sides, while the surface of the new fold mirror is silver/reflective on one side
and black with a pin-sized through-hole to allow partial light transmission on the other side.
10. On the new housing, locate and loosen the captive faster holding the metal guard to the
housing.
11. Slide the metal guard from the shoulder screws holding it in place. Discard the guard.

10. Slide the card cage out along the guides.
To avoid possible damage, carefully place the card cage on a clean, flat surface.
Cleaning optics (excluding lens)
Unnecessary cleaning of optics can be more harmful than helpful by increasing the risk of damage to
delicate coatings and surfaces.
Only clean optics when dust, dirt, oil, fingerprints or other marks are obvious or are the cause of
performance problems. Maintenance of optical components requires a qualified service technician.
Inspect exposed optical surfaces periodically in a clean, dust-free environment using a flashlight.
Always wear appropriate gloves when servicing any optical surfaces.
Supplies for cleaning optical surfaces
• Soft camel-hair brush
• Dust-free blower: Filtered dry nitrogen blown through an anti-static nozzle
• Dust-free lens tissue, such as: Optowipes (18LAB022), Kim Wipes, or equivalent
• For lens only: Lens cleaning solution
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfiber
Replacing the color sensor board harness
If the color sensor board harness becomes damaged during installation, replace it with the enhanced
harness included with the kit.

This process takes approximately one minute. DAC calibration is only required after replacing
the color sensor board.
5. To complete the calibration, reboot the projector.
Performing the LiteLOC v1 calibration
Due to the manufacturing tolerance of the color sensor board and the LOS system, calibrate the
LiteLOC v1 response to the light intensity as the temperature of the laser devices changes.
1. Contact Christie Technical Support for a copy of the Horizon Factory Calibration Procedure
spreadsheet.
2. On the projector, display a framing test pattern.
3. Setup the color meter in the same manner as used for creating laser and MCGD files.
4. Login to the projector with Installer access or higher.
5. Navigate to the laser power settings page.
6. Set the following values:
• LiteLOC is disabled
• Maximum Expected Room temperature: 35 degrees Celsius
• Red power level: 78.3%
• Green power level: 63.2%
• Blue power level: 66.4%
7. Wait 15 minutes for the laser devices to acclimatize to the new values.
8. Adjust the blue and green power levels to achieve an applicable white point, as measured by
the color meter. Do not adjust the red value.
• For CP43XX-RGB series projectors, the DCI white point is x=0.314, y=0.351.
Wait a few minutes for the lasers to stabilize and ensure that the white point is not shifting
between measurements.
9. Re-establish the connection to the photon controller using NetTerminal or Kore 10-bit Librarian,
on port 5103.
10. Send the command (RGB + MEAS?) to the photon controller.
The current color sense X, Y and Z values are returned, showing the temperature of the
different devices. For example:
• Red: Color sense X value
• Green: Color sense y value
• Blue: Color sense Z value
