A customer of mine had a friend that broke his school provided MacBook, and they wanted $700 from him for the fix.
I usually don't work on laptop hardware outside of disks and ram, but with this easy guide, I thought it was worth a try. Honestly, it was one of the easiest things I have done on a laptop. Don't know if I want to try fixing my son-in-law's glass screened aluminum MacBook, but this unibody model is a piece of cake!
Be aware... If you are testing the panel for dead pixels before you button things up (like I always do), the protective plastic sheet on the panel has a design of roughly 30 pixels (in red) in the lower left quadrant. I briefly thought I had a bad panel, but quickly pulled that sheet off to see everything was fine.
