The LED arrays for the backlight have failed.d. The inverter has failed.

Answer 1

Answer:

d. The inverter has failed.

Explanation:

In a thin-film-transistor LCD Display, the inverter is responsible for determining the precise amount of power to be sent to the lighting system (flourescent lamps) that is situated around the display. when you notice a dimness from the display then there's a likelihood of the inverter being in a bad state.
