CompTIA A+ Core 1 (220-1101) — Question 535

A laptop is displaying vertical lines in different colors on the screen. Which of the following components should a technician replace to most likely correct this issue?

Answer options

• A. Inverter
• B. Motherboard
• C. Low-voltage differential signaling cable
• D. Liquid crystal display

Correct answer: D

Explanation

The correct answer is D, as vertical lines on a laptop screen often indicate a malfunction in the Liquid Crystal Display (LCD). The other options, such as the inverter and motherboard, are less likely to be the cause of this specific symptom, and a low-voltage differential signaling cable would typically not result in visible vertical lines.
