The display on my MacBook was blacking out more and more frequently. Looked up the problem and found this step-by-step guide to fix it on ifixit.com. Having the needed parts and tools tied to the article was a huge help!
The instructions were incredible - great pictures, very clear instructions. I was able to do it myself and save a ton of money in the process. I love how they have all the parts you need right there on the how-to guide. I received the parts/tools super fast, and the repair was a breeze.
My MacBook has a plastic shell. Be careful when re-assembling the unit, because it's easy to push the optical drive slot down a bit - making it hard to insert CDs. I was able to fix (my mistake) by opening up the slot a little with a knife later.
