|Sounds like a problem with either the video card or the LCD screen. Does this particular notebook have the ability to be hooked up to an external monitor via VGA? If it does, try that...|
a) External monitor has a picture
resoution: LCD screen is bad on laptop
b) External monitor has no picture
resolution: Laptop video card is bad.
If the GPU isn't built in on the laptop and you can open the case alright, then replacing a bad video card should not be too hard. you can look it up online, it's easy information to locate. If the LCD screen is bad, that's not quite so easily replaceable... it is most likely brand-specific, so you might need another "for parts" Thinkpad to do the transplant, or bring it to a computer technician.
^ my 2 cents... hope this helps.
