Color Sensor Board - Christie Cinema 4K-RGB Service Manual

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 (4 ¾
inches).
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 you cannot re-orient the
projector due to environmental or logistical constraints, all service operations can be
completed in landscape orientation: however an increased difficulty in component access, tool
manipulation, and an increased risk in component damage exist if glass elements are not
handled carefully.
3. Remove the bottom cover.
4. Loosen the two fasteners from the installed cover (A in the image below).
5. Remove the cover and set it aside.
6. Locate and loosen the four fasteners on the color sensor housing (B in the image below).
