Mostly out of idle curiosity, I asked this question recently on
a Thinkpad list.  Here is the response from someone who did it:

=====
I had to COMPLETELY disassemble the panel structure in order to
access the backlight. Complete disassemble means that I removed
all the sticky tapes, peeled off a white plastic sheet glued on the
circuit board, took off the metal frame, LCD glass panel, bunch of
various optical sheets and light guiding panel. Then finally the
backlight came out.

if small particles get in the LCD panel when putting everything together
again, they scatter or block the light, seen as ugly bright/dark spots.
So I cleaned everything up very carefully. This operation took almost
6-7 hours for me.

This operation definitely requires high level of skills and recklessness.
If someone out there dare to try it, I would say the very first thing to do
is to obtain a dead LCD panel and practice using it.
=====

Sounds like fun though :-)
