Hi Folks, Hope someone can help. My 13" MBA (first rev I think) display is permenantly white on power-up; external display OK. There's an inductor on the logic board (right next to the video cable connection) that has blown; it's marked "22UH 0752AB or ...AC". Does anyone have a cct layout diagram so that I can determine the exact spec of this part please? It's obviously rated 22uH, but what is the current/voltage spec. etc.. Ideally would like to match like-for-like, but that may not be possible. From what I've read/learnt, this seems a common failure when the right hinge sheers and the video cable is cut, shorting out this inductor. Ta, Nat.
