Blank Laptop Screen - Does a Dark LCD Screen Indicate a Faulty Backlight?

If your laptop screen is not completely dark or black - i.e., you can still see the desktop faintly - then it could be an inverter failure or a defective backlight bulb.

In most cases, it's a failing backlight rather than a failed inverter.

If you see intermittent bright images on your screen with pinkish tones then it's definitely the backlight. You can replace it cheaply for $6-12 with parts from Ebay or other LCD repair stores.

Make sure you get a backlight with the connector attached to it so that you can plug it into the inverter board.
