Answer to: Why does my upper screen have black streaks going down it. why?It's probably the LCD screen that has cracked. This causes liquid to pour out of the LCD and creates black spots that are not on top of, but really in the screen. If you can still see what is displayed, but only through a very thick black haze, or so it looks, that's probably what has gone wrong. It can occour by having the screen bend too much.
