Damaged screens are easily replaced:
With the LCD box in the horizontal (flat) position undo the six screws surrounding the screen using a 3mm allen key.
Carefully remove the front metal work and Soft Key strips (soft key strips are on Hog 4 Console Only).
With the LCD box in the vertical (upright) position undo the eight scews on the back panel of the screen assembly using a 3mm allen key. Remove the back panel metal work. (This entire step for Hog 4 Console Only)
With the back panel removed carefully remove the eight screws on the back of the LCD assembly using a 3mm allen key. Make sure you have somebody hold the screens from the front of the console while you do this. (This entire step is for Hog 4 Console Only)
Lift the screens from the console and unplug the cables from behind.
Replace with a new screen assembly by performing previous steps in reverse.
