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.
