CompTIA A+ Core 1 (220-1101) — Question 269

A customer's cell phone screen is discolored in several areas. Which of the following components is the MOST likely cause of the issue?

Answer options

• A. Bulging battery
• B. Wired connectors
• C. Liquid crystal display
• D. Phone case
• E. Protective glass

Correct answer: C

Explanation

The liquid crystal display (LCD) is the primary component responsible for the screen's visual output, and discoloration often indicates a failure or damage within this part. A bulging battery could potentially cause pressure on the screen but is less directly linked to discoloration compared to issues with the LCD. Other components like wired connectors, phone cases, and protective glass do not typically cause screen discoloration.
