I just purchased the Macbook Air rev 2 120gb HD model. I it has the problems with the lines on the screen. It flickers on the one test image from the forums, but does not appear to flicker during normal usage. Also, it has a sort of CPU buzzing comming from the left side of the keyboard. It gets worse then I move the trackpad. I was thinking of calling support on this, but I don't want to end up getting the same screen with the same problems. I was wondering if anyone has gotten any of this fixed. Is there some way that I can direct support so that they put in the correct model of screen? My current info for the screen is: P .00 6 B133EW03 V0 Color LCD Maker 610 9C9A What is the model of the good screen? Has anyone had the flickering problem resolved? If so, what part was replaced? What about the buzzing? I heard the buzzing may be the fan controller, flickering the screen inverter. Am I correct on this? I would appreciate any advice. Thank you.
