I assume you are talking about a laptop motherboard? If so, there is a ribbon that connects to the CFL tube controler (not sure of the exact nomen here),that provides the backlight power. look behind the LCD screen and make sure it is plugged all the way into it, if it is reseat it. That may solve your problem.
