Screen Backlight Service
The backlight for the LCD screen in most laptops is a cold-cathode fluorescent lamp, which is basically just a small fluorescent tube. Just like fluorescent room lighting, they eventually burn out. Unlike room lighting, they are not made to be replaceable.
If your LCD backlight is not working consider the possibility of the LCD not lighting up because of the blown fuse on your laptop’s motherboard.
You have an LCD that does not produce the backlight. You order and install the LCD with the new one, however, the backlight is still not functional. An LCD test kit will hep you thoroughly test the LCD, but not a lot of people have one at their disposal, and more often than not, it makes very little sense to buy one just to test a single LCD screen.
