I would like to add – several months later, my Macbook Pro failed to turn on and the motherboard had to be replaced. I'm giving partial blame to this guide for failing to adequately describe how to safely proceed on this step (I suspect a bad wifi card was part of the problem). Anyone else following this guide be very wary!
This step did not provide enough direction and is the reason my cable is either broke/not working now. I tried pulling it out of the logic board, as indicated, but it did not budge. I was extremely careful not to damage it, so I gave up on trying to remove it once I saw that it wasn't moving. Lo and behold, once I fired the Macbook up again, the camera is no longer connected. This step should have additional details/explanation as to why the cable may not come out/what to do if it doesn't (I was able to proceed to the next steps by working around the cable, so it didn't even have to be removed as the guide might have you think).
Does anyone know how to properly fix it/where to buy a replacement camera/iSight cable? I would like to fix this if possible.
