Could anyone send me a pic of the logic board connections mainly the connections near the airport extreme ribbon. I replaced my dc in and it works however my display is really really dim where it was not before the replacement. I think that maybe I have missed a cable when reassembling but i have no reference. I have looked at the ifixit guide but the specific cable is not listed there. Its a 4 pin connector on the logic board that does not have any connections and i am wondering if this is normal. Thanks in advance.
