I got drenched in some heavy downpour. My macbook pro was in my backpack in POWER OFF state. When I opened my backpack I could see that my Macbook had become wet. After letting it dry for 5 days, it booted up fine. But my display looks like this (see pics below). There is no flicker or anything but it has a stained layer behind/in the screen. Can this be taken apart and cleaned and put back or does the screen have to be replaced? Is there any liquid between the backlight and the retina panel? Also not able to figure what that diagonal line is. Definitely not a crack, as I haven't dropped it. Need some insight.
