Section 2: Service Guidelines
2.9
Replacing Modules
Service the projector in a clean environment to prevent contamination of internal parts. 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 the projector and that the module is replaced
properly. Replace any component that shows signs of overheating.
2.9.1 Repair Cautions
• DO NOT operate with water blocks removed.
• 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, the projector must be
operated without the lid and/or lamp door, ensure that UV GLASSES are worn and stand WELL BACK
from the projector at all times.
2.10 Cleaning
ELECTRICAL SHOCK HAZARD! Ensure that the projector is completely powered down
and disconnected from AC before the lens or any of the projection head covers or doors are
loosened and removed. Wear gloves when handling internal components.
Maintaining the cleanliness of all internal components during any service procedure is critical. In particular, all
of the projector’s optics must remain free of contaminants in order to perform at the level specified for the
projector. Even a small amount of dust or a fingerprint may degrade the image or cause a noticeable reduction
of brightness. During servicing, take all necessary measures to avoid touching or contaminating optical
surfaces. Always wear gloves (provided) when handling internal components. A
minimum
amount of
cleaning—
typically none
—should be required during and after servicing. Ensure the projector is
OFF
and
disconnected from AC
before cleaning. Reference
