The inverter is connected to the backlight and an important thing to replace. Often a dying or failing laptop monitor has a variety of visual effects. These are great to memorize as a tech so you can make a quick deduction. You don't every effect all the time but they're usually very easy to spot and identify quickly.

A. LCD panel: The LCD panel is responsible for displaying the images on the laptop screen. If the display has become very dim and adjusting the brightness/contrast controls does not have a significant effect, it suggests a problem with the backlighting system of the LCD panel. This could be due to a faulty backlight or backlight inverter, which is typically built into the LCD panel itself.
