Question
A technician is troubleshooting a classroom projector that shuts down after fifteen minutes of use. Which of the following should the technician do to resolve the issue?
A. Replace the video input cable.
B. Change the bulb.
C. Clean the air filter.
D. Swap the power cord.
Answer
C. Clean the air filter.
Explanation
Projectors rely on proper airflow for cooling and heat dissipation. When the air filter becomes clogged with dust and debris, it restricts the airflow, leading to overheating. As a safety measure, projectors are designed to shut down automatically after reaching a certain temperature threshold to prevent damage from overheating. Cleaning the air filter regularly ensures adequate airflow, allowing the projector to operate without prematurely shutting down due to overheating.
