all servicing.
Read all instructions before servicing. Always take extra precautions to secure all harnessing properly,
especially in the high voltage circuitry areas. Replace any wire that appears to have damaged insulation.
Components must be replaced with exact equivalents. Failure to do so may result in unsafe operation.

Lead Dress

Before servicing, always carefully observe the original lead dress. Take extra precautions to secure all
harnessing properly, especially in the high voltage circuitry areas (such as lamp cables). Replace any wire that
appears to have damaged insulation.
2.2

Ordering Parts

When ordering replacement parts, quote the part numbers of the items required as listed in
Module Replacement. Also quote the projector model number, serial number, and date of manufacture, as
indicated on the license label. NOTE: Not all parts are available separately. In addition, some parts stocked as
inventory are available only until the current supply lasts. All part numbers are subject-to-change.
2.3

Replacing Modules

Check module markings, parts lists and the relevant disassembly/replacement procedures outlined in
Section 5 Parts and Module Replacement
module is replaced correctly. Components must be replaced with exact equivalents. Failure to do so may result
in unsafe operation.

Repair Cautions

DO NOT
• short transistors or ICs during circuit checks.
DO NOT
• short or remove bias resistors while the projector is operating.
DO NOT
• operate with heat sinks removed.
DO NOT
• overload transistors or ICs. Ensure the projector is disconnected from AC power before testing,
removing, or installing modules.
DO NOT
• operate the projector with any internal part removed. If, for testing purposes, you must operate the
projector without the lid and/or lamp door, ensure you are wearing authorized protective clothing, such as
that included in the Christie Protective Clothing Safety Kit (P/N: 598900-095).
DANGER! NEVER strike the lamp or run the lamp with the lamp door removed.
