one thing worth checking would be if you can hook the laptop upto an external monitor - if this works ok it means that the problem lies with the actual screen. If it doesnt work then it is likely to be the graphics controller card which on most laptops is on the motherboard, which would mean you were pretty screwed.
Screens can be fixed, although often it isnt economical to repair them.
Can you tell me the make and model number of the laptop, might be able to tell more if we know that.
Bugger, you were quick!!
