Attention when replacing LCD Panel
      (1) Attach a VESA Metal Up (with VESA Metal) to the LCD Panel for repair.
      (2)  As shown in the following figure, please attach beforehand the Clamper for paste included with LCD Panel for 
repair.
      (3)  Check that the FFC (from V1-Board) and the lead wire (from Touch Module) are taken out to the outside of the 
Cabinet.
      (4)  Two person hold the narrow-side of LCD Panel and raise it, and move to the Cabinet. Since the worker who car-
