So I was just messing around with the screen I had from a DS fat that had a few stuck pixels on it. I was trying different things like poking at the pixels and such, didn't work BTW, and then I was cleaning the screen and all I had was some isopropyl alcohol so I put some on a cloth and wiped. I guess some got under the screen because it started to look REALLY strange, like the screen was cracked but the picture was fine but kind of see-through. So I figured I must have cracked the screen and took it apart to get at the backlight and turns out some of the isopropyl alcohol had gotten behind the LCD and damaged the plastic used in the backlight. I tested it again by taking the plastic and just dripping some isopropyl alcohol onto it and sure enough it caused the same effect of making it turn milky white when it dried. So yeah, don't use isopropyl alcohol to clean your LCD's. I only tried it on a DS fat LCD but I am going to assume the lite/i have the same kind of plastic behind the screen.
