Hey guys. I've booked an appointment to see an apple genius about a problem with my MBA screen. I have apple care and it's a 2011 MBA in the apple care period. For a long time there's been a white spot, which kind of looks like the top part of an over grown finger nail in the top left of the screen! I've since noticed another one develop on the bottom right part of the screen. You can only see them at certain angles and it's most visible on white or yellow backgrounds. It's quite distracting and annoying as my eye is often drawn to it. Now, I've had really bad service before with this MBA at the genius bar. I had a lot of creaking in my MBA, like really pound. The genius simply said 'it's within tolerances' ... after a lot of fussing and me being made to feel like an idiot, eventually another genius opened it up and it turned out the battery clip wasn't installed properly and was causing the creaking. I'm expecting terrible service when I take my MBA in this time as well. I'm fully expecting them to say I damaged the screen myself without considering anything about the situation. I've done some searching and read people with similar issues have had their screens replaced so that's a good sign, but I'm not expecting to be so lucky. I know there has never been any accidents with this machine, it's flawless cosmetically. So I will argue there are no physical marks on the screen or body, so I haven't caused these weird white spots. I however have no real knowledge of how lcd screens work but this thread here talks about 'Mura' and posts an image further down the thread that looks exactly like my screen! Exactly the same! https://discussions.apple.com/thread/4042189?start=0&tstart=0 The point of this thread is, as I know nothing about lcd screens - I need your knowledge so I have some fire power about why this issue isn't because I've damaged my mba and it's a defect in the screen. Thanks very much for your help, Rich.
