Maintenance Tips
-
Avoid frequent on/off cycles: Keep sessions longer; repeated starts shorten lamp life.
-
Proper cool-down: Always let the projector fan finish its cooling cycle before unplugging.
-
Handle with care: Install only when cool; avoid touching the glass or reflector surface.
-
Dust control is critical: Clean air filters regularly—overheating is the #1 cause of early lamp failure.
-
Ventilation matters: Keep rear/side vents clear (at least 20–30 cm space) for heat dissipation.
-
Use Eco Mode when possible: Reduces power load (430W class lamp) and can extend life up to ~4000 hours.
-
Stable power supply: Use a surge protector or voltage stabilizer to protect the ballast and lamp ignition system.
-
Avoid vibration: Do not move the projector while the lamp is running or cooling.
-
Replace proactively: Typical life is ~2000 hours; replace before brightness drops or flickering appears.
-
Clean only externally: Never open the lamp housing unless replacing—high-voltage components are present.
