Blank Laptop LCD - How To Fix A LCD Display That Has Gone Completely Black

If you can still see the laptop's startup screen faintly then your display is fine and you don't need to replace it. Just shine a torchlight or flashlight into the screen and you will see a dim silhouette of your desktop area.

When a LCD display goes partially or fully blank, it is most likely a backlight or inverter problem. It can also be the wire that carries electric power to the backlight tube.

In either case, it is cheaper to replace the inverter or power wire than the whole screen. You can buy cheap replacement LCD parts for $9-12 based on your screen size & brand.
