And more importantly, did the lines disappear using rev A display? (Assuming you did it because of lines on rev B display)
The MBA Rev. B is a noisy device to begin with. The audio out jack is extremely noisy when hooked up to a TV with the display port as well. This could be compounding an issue for some.
I found the screen much better after it was swapped. (Perfect to me)
Scottsdale, If you want, I can help you with the procedure.
On a side note.. Anyone here find their display hinge soft/not tight on their 2.13? I wouldn't call it floppy, but it definitely moves REAL easy compared to A & B.
