A customer's laptop display has suddenly become very dim.
The image of the display can only be seen with a bright, external light, as adjusting the brightness/ contrast controls does not cause much change.
Which of the following components MOST likely needs to be replaced?

A. B. C. D.B.
Based on the symptoms provided, the most likely component that needs to be replaced is the inverter.
The inverter is a small electronic component that is responsible for providing power to the backlight of the LCD display. If the inverter fails or malfunctions, the backlight will not receive enough power, causing the display to become dim. Adjusting the brightness and contrast controls will not make much difference in this case because these controls only adjust the brightness of the image on the screen, not the brightness of the backlight.
On the other hand, if the LCD panel were the cause of the problem, adjusting the brightness and contrast controls should make a noticeable difference in the brightness of the image on the screen. A faulty video card or digitizer would not cause the display to become dim.
Therefore, the best option in this scenario is B. Inverter.
