A much simpler process for this is to remove the two screws at the bottom of the screen, flip the screen to 90 degrees out from the body, and remove the two screws on the back. Then the top plastic piece can be worked loose and the LCD frame can be removed from the metal bracket.
Reinstallation is a little bit tricky because the plastic piece and the metal back plate much be held in place along with the LCD frame before any of the screws can be reinstalled.
Note that there is a plastic spring piece that clips in the top of the LCD frame, and also a clear/white plastic piece that sits on the light sensor element in the corner of the screen.
Long story short is that the metal LCD hinge does not need to be removed from the body in order to replace the LCD…. so, 4 screws instead of 28.
