My dad has a 2007 Macbook Pro and everytime he moves the computer, even just slightly, the screen flickers and either goes blank or the colors invert. It looks like I can order the display from iFixit, and I'm confident I can install it myself. (I've swapped out my optical drive in my Macbook along with replacing batteries, etc.) Has anyone had experience with Apple repairing this and what it might cost? He can't afford to buy another computer and I thought I would try to have this fixed as a Father's Day present.
