If any part of the screen is illuminated then the inverter board is  
functioning.  If I recall correctly, there are several separate  
fluorescent emitters in the screen.  The connection to one or more is  
broken.  The easy fix is to replace the screen.  You can open it and  
look for a connection problem.  The screen is glued together but it  
can be opened.  I had to do that to replace a broken hinge.  The glue  
they use is not super strong.  Remove the small screws in the border  
that attach to the hinge, then slowly and carefully pry the layers  
apart with a wide blade, such as a putty knife.
To reassemble, I forget which glue I used but I'd avoid something  
really strong like epoxy in case you need to fix it again.  "Shoe  
Goo" or a similar would probably work ok.  Even a cyanacrylate (like  
Super Glue) would work well if used sparingly.  Test the light before  
gluing anything...  If you use a stinky organic-solvent glue like  
Shoe Goo, test a bit on the plastic parts first to make sure the  
solvent doesn't damage it.  Once it is together, clamp lightly by  
putting a book on it to make sure the frame is not bowed while it dries.
