lamp is bad. The other one might fail shortly.

Refer to the "Display Removal" procedure on page 3-27. Unplug the
backlight cables from the backlight connectors
It is not necessary to remove the display mount from the front frame to
change the backlights.
The following Figure shows how the backlights slide out of the display.
Carefully pull on the tab on the backlight assembly (2) to slide the
backlight partially out of the display. Once the end of the backlight casing
is exposed, you can pull it straight out from the display.
NOTE: Do not touch the bulb encased in the plastic backlight assembly.
