Start in the lower left corner. Insert a plastic wedge under the bracket and 
apply pressure upward to free the bracket from the back cover. Insert 
another plastic wedge one tab at a time along one side of the bezel. Free the 
bracket from the one corner and this frees the bottom of the bracket. Free 
the bracket from one side. Repeat the procedure on the other side. Freeing 
the sides will free the bottom of the bracket. Finally, free the bracket from 
the top of the bezel. The two top tabs should come free easily. 
To reinstall the bracket, the LCD cable harness and the inverter board cable 
must be under the bracket and through the correct channels in the bracket and 
the back cover. Be careful not to break the hidden plastic tabs when reinstalling 
the bracket.
