CompTIA A+ Core 1 (220-1101) — Question 132

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?

Answer options

• A. Replace the video input cable.
• B. Change the bulb.
• C. Clean the air filter.
• D. Swap the power cord.

Correct answer: C

Explanation

The correct answer is C, as a clogged air filter can cause the projector to overheat and shut down automatically to prevent damage. Replacing the video input cable, changing the bulb, or swapping the power cord are unlikely to address the overheating issue caused by a dirty air filter.
