CompTIA A+ Core 1 (220-1101) — Question 224

A technician is troubleshooting a projector that will not display any images. The technician has verified the computer output and cable are providing a good video signal. Which of the following should the technician do NEXT?

Answer options

• A. Calibrate the image.
• B. Replace the bulb.
• C. Test the output resolution.
• D. Clean the fans.

Correct answer: B

Explanation

The correct answer is B, as a burnt-out bulb is a common cause of a projector not displaying images. Options A, C, and D are less relevant at this stage since the technician has already verified the signal, and issues related to calibration, resolution, or cleaning fans would not address the immediate problem of no image output.
