(Maybe it's already winter time in your place, that's why its snowy? ...)
Kidding aside, I tried to remove my LCD panel/touch screen recently because I had a problem with it (not responding to touch), and when I put it back, I forgot to "lock" the clip for the ribbon wire so it's kinda loose, and the screen was also like that, only lines were present but cant read or distinguish whats written on the screen. MAYBE your ribbon wire is loose? I'm just guessing though, based on my experience
