Now that the front part of the case has been removed there should be four screws at the bottom corners (two in each corner) and two on the top left and right corners. These screws are connecting the screen to the back of its case.

Unscrew all 6 screws as so that the screen can be taken out of the case. These screws are 3mm in length.

There is also a cord that runs through the case. Make sure that is removed safely without damaging the cord.

The screen should be able to be fully separated from the case.
