6. Fit new backlights.
The backlight for the top is different from that for the bottom.
Fit projections and dents of the backlight with those on the fixture, and shift
the backlight to the left. Check that the backlight is in contact with the left
end of the fixture and the cable comes out from the notch without being
trapped.
When the backlight is correctly fit, tighten the screws at a torque of
0.1 N·m.
7. Engage backlight connectors at the top and the bottom respectively in
place. The backlight cable has a polarity; refer to the figure below.
8. Fit two touch panel cables at the top. Be sure to lock the connectors as in
step 4 after fitting.
9. Close the rear case, and tighten four screws. Make sure that the internal
cable is not trapped.
