CompTIA A+ Core 1 (220-1101) — Question 489

A user creates a support ticket to report a conference room projector that does not work. The user says that even though the provided cables are being used, the projector screen shows the following error message:

No Signal Input -
Which of the following describes the FIRST action that should be taken?

Answer options

• A. Verify that the projector is turned on.
• B. Verify that the user is using an approved OS.
• C. Replace the projector bulb.
• D. Check the video cable and replace it if necessary.

Correct answer: D

Explanation

The correct first action is to check the video cable and replace it if necessary because a 'No Signal Input' message often indicates a connection issue. Verifying the projector is turned on (option A) is also important, but if the cables are faulty, it won't resolve the issue. Checking the OS (option B) is irrelevant in this context, and replacing the bulb (option C) is unnecessary if the projector is not receiving a signal.
