The screen assembly is a delicate component and some prying is involved. Avoid deforming screen to avoid further damage.

Gently bend the matrix away from the screen to release the pressure clamps.

Bend one side at a time applying equal force in order to reduce stress on the matrix from the bending.

Once all pressure clamps are disengaged, separate the screen and matrix without touching the front of either component.
