CompTIA A+ Core 1 (220-1201) — Question 78

A technician needs to prepare a conference room for a meeting. The technician connects the laptop to the LCD projector and audio system, and then verifies the connectivity of each device. The meeting begins, but the visual presentation suddenly cuts off 30 minutes later. The audio continues to play without interruption. The technician brings in a backup laptop and connects it to the projector. The meeting continues without issue for 15 minutes until the presentation suddenly cuts off again. Which of the following should the technician do to resolve this issue?

Answer options

• A. Check the laptop's audio output
• B. Verify the input source.
• C. Examine the display for burn-in
• D. Inspect the cables for damage.
• E. Clean or replace the filter

Correct answer: E

Explanation

The correct answer is E because a clogged or dirty filter can cause the projector to overheat and shut down the display, while the audio continues. The other options do not address the likely cause of the issue, as they pertain to audio or input checks rather than the projector's functionality.
