A few months ago the iSight in my MacBook suddenly stopped working. iChat just told me that I didn't have a camera attached and the iSight was no longer listed as being on the USB bus in System Profiler. I'd borrowed my old PowerBook from my sister and was all set to send my MacBook in for repair (along with it's orignal crashed hard disk) when i thought i'd have a go at fixing the problem myself in case it was just a loose connector. I had thought that I'd have to practically dismantle the whole machine to get at the wires but you can at least get to one connector by just unscrewing and lifting back the screen. I found this posting on removing a MacBook iSight and this article from ifixit.com that better explains how to remove the bezel. After I removed the bezel and unscrewed the screen I found the connector and, to my delight, it *was* loose. The USB cable zigzags up the back of the screen and is taped down in several places. It looks as though it is just a few millimeters too short to be taped to the surface 100% flat. I adjusted it a little and connected it properly.
Powered up my machine, and low and behold my iSight is back! This is excellent as it was certainly going to be a little painful to lose this machine for a week.
