Maintenance Tips
-
Always complete cool-down cycle: Let the projector’s fan finish before switching off power to avoid heat damage.
-
Avoid frequent on/off use: Repeated power cycling reduces lamp life and causes early brightness drop.
-
Keep air filters clean: Dust buildup leads to overheating and significantly shortens lamp performance.
-
Handle correctly: Never touch the lamp glass—use the module housing to prevent oil damage and hot spots.
-
Ensure proper installation: Fully seat the CPA100LAMP (DT00891) module to avoid flicker or ignition failure.
-
Use surge protection: Protect against voltage spikes that can damage lamp ballast and ignition system.
-
Maintain ventilation space: Blocked airflow is a major cause of overheating and premature lamp failure.
-
Replace at end-of-life signs: Dim output, color shift, or delayed startup indicates lamp wear.
