Procedure for replacing the backlight
(1) Unplug the power cord from the main power supply.
• Remove the PS-G unit from the equipment to which the unit has been incorporated,
and work with the PS-G unit with the display surface facing downward. Be sure to
perform the backlight changeover on a flat, level surface. This will prevent damage
to the PS-G unit and the accidental cutting of any of its power cord.
• Be sure to protect the display surface to prevent damage during the operations.
(2) Remove the retaining screws (7) on the rear cover, and detach the cover from the main unit.
(3) Open the circuit board chassis.
(4) Disconnect the Backlight Unit cable from the connector on the inverter board, and then remove the cable
from the cable clamp.
