Christie CineLife+ CP4415-RGB Service Manual page 83

Before servicing, always carefully observe the original lead dress. Take extra precautions to secure all
harnessing properly, especially in the high voltage circuitry areas. Replace any wire that appears to
have damaged insulation.
1. Shut down the projector and ensure it is disconnected from AC.
2. Remove the rear cover (on page 45).
3. Disconnect the three-pin MAIN or UPS inline connector (whichever is already connected) from
the 12V power supply module.
4. Disconnect the 4-pin unmarked inline connector from the 54V power supply module.
5. On both power supply modules, disconnect the DC output cables from the positive and
negative terminals. Retain all screws, washers, and lock washers.
There are four cables for the 12V power supply and two cables for the 54V power supply.
6. Loosen the three fasteners securing the power supply module to the projector system.
