I've been reading this blog about hardware hacking, repair, and general take it apart to see how it's made-ness called Savel.org. Good reading if you've had a little EE schooling.
In this entry the author talks about LCD repair, a particularly good skill to have when it comes to LCD's crapping out in notebooks.
"To begin repairing the LCD monitor you must have some soldering skills. Some spare LCD modules and some spare LCD controllers. These are used to test you new acquired LCD monitor modules. The LCD module can be broken (if have on with crack in the matrix), the only use of that part is to check if monitor is working."
