LCD problems?

[ccookie66]

Hello, I noticed that my IBM Thinkpad t40 laptop screen would go blank, but I could still see the windows, just a little. Pressing Fn+F7 would work at first, but now it goes off right after I do that. I thought it was the LCD inverter, so I got one, and replaced it. Didn't change a thing. What could this be?

Could be sticking lid switch, burned out ccfl or even defect in the LCD ribbon cable.
