Maintenance
Your projector needs little maintenance. You should keep the lens clean because any dirt or smears appear on the screen. You also need to periodically clean the air filter at the bottom of the projector. A clogged air filter can block ventilation needed to cool the projector and keep it from overheating.
The only parts you should replace are the lamp and air filter. If any other part needs replacing, contact your dealer or a qualified service person.
