„ Preparation
Please have the following ready beforehand.
• Replacement backlight (Model: CA7-BLU15-01 (Set of two lights))
• One pair of clean (preferably new) cotton gloves.
• Phillips screwdriver (no.2)
„ Replacement procedure
Be sure to wear gloves when exchanging the backlight, and follow the following procedures.
(1) Turn OFF the power switch of the PL and remove the power cable.
(2) Remove the PL unit from the equipment (panel etc.) to which the unit has been incorporated, and place
the PL unit on a flat, level surface facing the display face downwards.
(3) Remove the control box from the front module.
(4) Unscrew the four (4) attachment screws securing the rear cover on the front module, and remove the
cover of the module.
• The backlights are located at the top and bottom of the LCD. These two lights
must be replaced together.
• Be sure to perform the backlight changeover on a flat, level surface. This will
prevent damage to the PL unit and the accidental cutting of any of its power cord.
• Be sure to protect the display surface to prevent damage during the operations.
SEE 5.2 Installing/removing the front module and the control box (page 5-9)
• If the rear cover feels warm to the touch, you may get burned by the cover.
Replace the backlight after the PL unit is cooled down enough.
