    Do I need a new laptop LCD screen if my LCD screen is dim?

    You may or may not need a new LCD screen if the LCD screen is dim. If your LCD screen is dim it may be as a result of either 1) a faulty backlight or 2) a faulty inverter. The backlight is basically the light bulb in the laptop LCD screen which as one would suspect has an average useful life. The inverter, though, is a separate piece from the LCD screen. The inverter essentially 1) takes the DC power which the laptop runs off of and converts it into AC power and 2) steps-up the voltage to light up the cold cathode fluorescent backlight.

    We have found that when a laptop LCD screen is dim the majority of the time it is a result of a faulty inverter. Unfortunately, the best way to determine which is the cause of the dim screen is through process of elimination by trying either a new LCD screen or a new inverter and seeing which solves the problem. We highly recommend you purchase an inverter first as inverters are less expensive than LCD screens.
