holder.
Each backlight uses a cable
holder to prevent the cable from
becoming caught or pinched
when the PL’s rear cover is
opened or closed. Be sure both
cables are secured by their
holder before closing the rear
cover.
• Use an"0" sized Phillips screw-
driver to remove the backlight
attachment screws.
• Be careful not to lose any of the
small attachment screws.
• Do not let any of attachment
screws fall inside the PL unit’s
chassis or front panel area,
since it could cause an electri-
cal short.

connectors from the inverter board.
