Any voltage out of Q7010 on pin 1? Something that very commonly happens on these newer Airs is that D7012 fails and prevents voltage from passing through Q7010. I'd replace it first
R7010/11 ok? There's not much else here that can cause that unless DCIN_ISOL is shorted. Another thing that can happen is broken trace between D7012 and R7010. Also bad Q7010 is possible.
