Keep the projector's exhaust vent clean so it can take in air without being hindered. Blocking the vent will restrict the airflow and can cause the projector to overheat.
-
2
Place the projector at least two feet away from any wall. This will maximize the amount of air that can circulate and cool the lamp.

Clean the intake vent every few weeks to clear off any dust that may be building up.

Wait at least five minutes to turn off the projector after you have turned it on. This allows the fan in the projector to properly cool the lamp.

5
Power on your projector after purchase and leave the display on for at least 20 hours. A lamp will most likely fail within the first 10 hours, so if the bulb is going to fail early, it is best to get it over and get a replacement bulb free under the warranty.
