What is the make/model?  Some have fairly standard CCFL tubes for the backlight that can be purchased online.  You might even need to find the LCD model from the panel itself to find a proper tube.  Many times if the tube is dead it will have dark/black marks or even cracks.  Did this happen slowly, or did it get dropped/jarred/knocked funny or looked at crosseyed? ;)

Anyone here handy enough to do LCD repair? To make a long story short, I
get no display on my laptop anymore... well, I get a tad, but seems the
backlight isn't kicking on. I figure I'd buy a backlight and replace it
for the heck of it.<tearing that display apart was a damn learning
experience.... why does it take 500+ screws to hold this thing together?!>
