Hey, I just bought a used rMBP 2,6/16/250. After a few days of lurking in macforums i stumbled upon a thread about the retina display and the two brands(LG, and Samsung) and unfortunately i had the LG. And unfortunately i'm having the burn in problem too. 10 min later on a regular grey screen. Is this enough to return it to apple? (I'm still under the 1 year warranty) And if they decide to replace the product, will they replace the whole Macbook or only the screen? Thanks in advance.
