2 Service Guidelines
2.1 Before 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.
2.1.1 Ordering Parts
When ordering replacement parts, quote the part numbers of the items required. See Table 5.1.
2.1.2 Replacing Modules
Check module markings, parts lists and the relevant disassembly/replacement procedure in Section 5 Parts and
Module Replacement to ensure that you have the correct module for your projector and that the module is
replaced properly.
Components must be replaced with exact equivalents. Failure to do so may result in unsafe operation.
2.2 Safety Warnings and Guidelines
Always power down and disconnect power sources prior to servicing.
HIGH VOLTAGES MAY BE EXPOSED! Always unplug the projector prior to
disassembly.
CHRISTIE ACCREDITED SERVICE TECHNICIANS REQUIRED! All module
replacement procedures must be performed by qualified service technicians.
NON-INSULATED DANGEROUS VOLTAGES MAY BE EXPOSED! Always
disconnect from AC prior to disassembly.
OBSERVE ALL ELECTROSTATIC PRECAUTIONS! Use a grounded wrist strap
when handling electronic assemblies.
ALLOW LAMP AND PROJECTOR TO COOL DOWN! Once you have turned off
the projector, allow the cooling fans to automatically turn off before
disconnecting from AC and opening the projector. This takes approximately
15 minutes.
