LP500 Series Service Manual 47
Remove and replace the lamp fan
The lamp fan (526-0079-xx) circulates air over the lamp module. The lamp fan is part of the lamp
housing, and is also available separately. You can remove the lamp fan without first removing the optical
engine.
When you replace the lamp fan, you must also adhere a lamp fan heat shield (329-0306-XX) to the
inside of the fan.
1 Remove the chassis and power supply from the bottom case (see page 39).
2 Remove the two M3x12 Plastite Torx screws that fasten the fan to the rear of the lamp housing.
Then remove the fan.
Assembly Notes
♦ Before installing the new lamp fan, you must adhere a heat shield to the center of the fan. The heat
shield must be placed over the label that is already on the fan. This side points toward the fan.
