I had a broken inverter cable because I could only open the macbook in certain positions.
It took me the first time 3 hours and when I finally turned the computer on it was all pink and some green spots. So I asked for help, just to find out what could be the problem before taking it apart. So a member here helped me. He assumed it was a loose cable. I could not believe because I attached everything. But I gave it a try. I did all the steps again and really payed attention on the cables and connection. So then the moment to turn on the computer....I DID IT. I am so happy with IFIXIT for the super service, fast shipping and lots of money I saved to fixit by myself. It would problably cost me 200.
Step 32 http://www.ifixit.com/Guide/Installing-M... confused me a bit with the picture. The added picture is from a macbook Santa Rose /Penryn early 2009. And the inverter cable is above it with a little piece of black foam on top.
