A projector in a conference room has been shutting down randomly during meetings. You've checked the operational hours for the bulb, and they remain well within its lifespan. You have also verified the seating and integrity of the bulb. You hear the whir of the fan from the projector from several feet away, but no grinding or knocking. There are no power-saving settings turned on. There are heat warnings visible on the interface. You suspect that you may need to replace:
A clogged dust filter is a common cause of projector overheating and subsequent shutdowns. When the filter is blocked, airflow is restricted, preventing the fan from effectively cooling the internal components, especially the high-temperature lamp. Given that the fan is operational and the bulb is within its service life, replacing the dirty dust filter is the most logical first step in resolving the overheating issue.
