and possibly damaged. Be sure to insert the cable in the cable clamp around the
cable before replacing the rear cover.
• If any of the screws is missing, check if it fell inside the GP unit’s chassis. If the
power is turned ON while a screw is inside, it may cause an accident or fire.
• After backlight replacement is completed, turn the GP unit’s power ON and check if the screen’s
display is normal. If the display is not correct, please contact the GP distributor from whom you
purchased the backlight unit.
