I have a 2010 15" MacBook Pro and have had this "red for black" problem for several years. by changing the angle of the screen, I could get the black back. It has gotten worse and the Mac is now almost unusable. I read somewhere that Apple knew about the problem and extended the warrant but did not publicize it. Last year, I took it the Apple store in Manhattan (Chelsea) and was told by a clerk that they no longer have the part(s) to fix it. The clerk identified the problem by bending the screen back and fouth. He gave me a preprinted list of four companies in NYC who would fix it for $400. I live in Michigan and am in the process of finding a repair shop that will make the repair.
