here is the damage to my screen. I warped that corner trying to pry off the screen. The piece that cracked off is presumably as a result. At first it was just a crack, I noticed it was cracked so I tried to see if that piece was loose, and it came off. (the piece is sitting in the midfle of screen in the first picture) These things may be the reason the screen doesn't work, rather than the ribbon cable connector. I do not know for certain.
