Hey guys, I bought a second hand MB Pro with retina two weeks ago. Today I noticed a pink and blue pixel cloud that is noticeable at the bottom middle of the screen with a slight strip going up the middle. The laptop was sold 8/2013 and is still under warranty. There is no damage at all to the outer casing, nor are there any scratches on the screen. It is in wonderful condition and I didn't notice this until today. You can only see the "cloud" on dark grey or dark blue backgrounds, not on black, nor other colors. It looks like colorful sand. You can click for a larger image. What is the recommended way to get this fixed? Am I eligible for warranty even as the second owner?
