Unscrew the 7 torx screws. Do not forget the one under the printer label (You have to remove the printer label. Lower right corner).

Push the clips at the rear of the LCD panel and pull the LCD panel outwards at the same time. The clips can be felt, but not seen underneath the plastic on which the HP label is visible in the middle picture. A fourth picture would help here.

Then, pull the ribbon connected to the LCD panel to disconnect the LCD panel from the printer.

Remove the 2 remaining torx screws hidden by the LCD panel
