(Required Tool)

Do not touch cables and boards that are not associated with backlight

unit replacement. Doing so may result in failure.

When replacing the backlight, take appropriate preventive measures

against static electricity.

* The point of measures against static electricity is to keep the entire workplace including humans at

the same electric potential. Use an anti-static wristband or mat to prevent static electricity.

1. Turn the POD over, and remove the 4 external screws.

Place it on a cloth, etc. to protect the display panel from scratches.
