webcam is a USB device, check voltage on pin 6 and diode mode on pins 2 and 3... Also could be a bad L3407 ....

Pin 6 is strange, it goes up and down between 1.1v and 3.4v

and diode mode on pins

pin 2 -1.75
pin 3 -1.73

and L3407 seems good compare to known good board.

Ok discovered that L3408 was visibly bad and i replaced it, now i get 5v on pin 6 and the green webcam led lights up but there is no image in facetime or photobooth, not even the no camera logo its just black.

Replace L3407. It can measure fine on a meter but still not be sufficiently well to pass high speed data.
