pressure, slide the bulb into the guide until the retaining clip locks.
Gently position the backlight bulb’s wires back into the wire guides.
Position any excess wire length in between the printed circuit board and
the LCD to prevent it from becoming pinched between the housing and
bezel.

that the flat ribbon cable on the housing aligns with the recess in the front
bezel. Insert the four screws and tighten to a maximum of
70 oz-in [0.5 Nm].
