Unfortunately, one of my relatives spilled coffee on their unibody MacBook Pro. Specs: 15" MacBook Pro 2.66 GHz Intel Core 2 Duo 4GB Ram Antiglare Standard res screen (1440x900) She brought it to a repair shop where they took it apart, cleaned, and let the internals dry. After a week, she brought it to me, who powered it up and it worked!! Here's the problem: the screen works but doesn't work. The repair place replaced the LVDS cable, but that didn't do anything. Stuff shows up on the screen when I shine a light up to it, so is it possible that the liquid shorted out the backlight or something? Any help is appreciated, thanks!
