Hey y'all, first time iPad user here. I recently bought a refurbished 16 GB iPad 3 (WiFi) online through the Apple Store website. It arrived in pristine condition and has worked great for the last 3 months. However, I was watching a movie in bed last night and noticed some white patches at the top of the screen where the letterboxing was. Further investigation and testing confirmed that my unit definintely has some backlight bleeding, It's looks like maybe 10-15 small white patches along the top and left edges. This is what it looks like with a completely black screen and maximum brightness in a dark room: I have no prior experience with this issue or iPads in general, so do the knowledgeable folks on this board think I should go to the Apple Store and request an exchange? Since I am still early in my warranty period it would be best to do this sooner rather than later. Is it possible to get a perfect iPad with absolutely no bleeding on any of the edges (like the bottom and left in my picture) or is this just something inherent in the design/manufacturing of the device? Thanks for the help!
