Answer to "Pink lines in white space, green lines in black space?"dan's right about the reballing. I heard it is labor intensive, requiring skills and tools that aren't easily accessible. I did go to the Apple store and told them that I thought it was the display (when I really figured it was the logic board). They took the laptop from me and I paid a flat fee of $310 (+tax), the invoice said they replaced everything but the harddrive and the fans-point is, I believe you can get your mobo replaced/fixed for the flat fee.
Answer to "Pink lines in white space, green lines in black space?"I've had this problem for a couple of days and I haven't found a concise solution online. So, I found that it was the connector for the display on the mobo itself. When I wiggle it, the screen gets worse and can go black/white also. I have ordered another cable on newegg. I hope that helps someone!
