I recently had a screen fail on a laptop, the problem was with the backlight, the image was still there on the screen but very dark.
To get the thing set up to an external monitor so that I could copy the important stuff off the disc to another computer, I illuminated the screen from the front with a bright torch.
It was a bit of a struggle, I could only see a bit of the screen at any one time but I managed to do it ok and eventually got the external monitor running so I could copy off my data.
So, if your problem is the backlight, try that, but if there is just no drive to the screen sorry I have no ideas.
