Install the new top cover assembly by first connecting the wire connector to J4 on the power
distribution PWA. Make sure that other end of the cable is connected to J2 on display PWA located
in the top cover.
12
Connect the ribbon cable from the display PWA to P4 on the main PWA. See figure in step 6.
Connect the 3-pin cable (wire colors orange, orange, gray) from the transformer to P5 on the main
PWA. See figure in step 6.
