1 Introduction
This manual provides information and procedures for servicing the J Series 2.0, 2.4, and 3.0kW projectors.
This manual assumes a familiarity with J Series functionality.
Only accredited Christie technicians who are knowledgeable about the hazards associated with high-voltage,
ultraviolet exposure, and the high temperatures generated by the projector lamp are authorized to assemble,
install, and service projectors.
1.1
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.
1.1.1 Repair Cautions
Ensure the projector is disconnected from AC power before you start testing,
removing, or installing modules.
Do not operate the projector with any internal parts removed. If for testing purposes,
you must operate the projector without the lid and/or lamp door, ensure to wear UV
glasses and stand well back from the projector at all times.
