Do not remove the back side of the case, just flip it over. The speaker is connected by wires to the main body, but positioned in the back case.

Flip the LCD to the bottom. You can not yet remove it, because it is still attached to the board.

The LCD cable is held into the connector via some compression clips. Move both ends carefully away from the connector, toward the LCD.

The clips only move about an 1/8 of an inch. Be careful not to use too much force.
