LCD inverters are the part of the monitor or screen that powers the backlight, according to Foner Books. Problems with an LCD inverter are very common and can make your LCD screen almost impossible to use. Chances are good that if your LCD screen goes out, you have a problem with the inverter board.

An malfunctioning inverter usually causes the LCD screen to go dark, according to Laptop Repair 101. The screen may look normal when you first power it on, but will dim after a few minutes of use. You might still see some sort of image, but it will be so dark that you need a flashlight or a lowlight situation to see it.
Odd Colored Screen
A malfunctioning LCD inverter may result in your screen becoming washed out with another, such as pink. The screen may look normal, but has discolouration in the background. You may even experience other symptoms, such as strange noises and the backlight flickering on and off.
Sometimes, a bad LCD inverter may not light up the screen at all, according to Laptop Repair 101. You might still make out a very faint image even if the screen never powers on. Sometimes the bad LCD inverter can even make buzzing noises from its location (usually at the bottom of the screen).
Even if you have a very poorly functioning LCD inverter you should still be able to make some sort of image on the screen, according to Laptop Repair 101. If you have a dark screen and do not see any sort of image, you probably have some problem other than a bad LCD inverter. (see ref 2)
