I have a Black Macbook, late 2006 version. The superdrive recently stopped working, so I purchased a new one and just finished installing it (following the steps outlined here: http://www.ifixit.com/Guide/Repair/MacBook-Core-2-Duo-Optical-Drive-Replacement/518/1). Once I had everything back together, I powered up the macbook, but the display shows no image. The power light comes on and I can here the computer working and making the normal start-up sounds, but there is no image. Any ideas of what I did wrong and how I can resolve the issue?? Any help would be GREATLY appreciated!! Thank you in advance!
