Remove And Replace The Lamp Blower - InFocus LP500 Service Manual

Remove and replace the lamp blower

The lamp blower (526-0078-xx) circulates air over the lamp module. It fastens to the back of the lamp
housing on the optical engine. The lamp fan is included with a new optical engine, and is also available
separately. You can remove the lamp fan without removing the optical engine.
When you replace the lamp blower, you must also adhere a PSA square (329-0251-XX) to the side of the
blower and a blower heat shield (329-0337-xx) to front of the blower. The blower gasket (329-0299-xx)
fits between the blower and the lamp housing.
1 Remove the chassis and power supply from the bottom case (see page 39).
2 Remove the M3x8 Plastite Torx screw that fastens the blower to the lamp housing. Then pull the
blower out of the lamp housing. When you remove the blower, you can see the blower gasket
beneath the flange through which the screw fastens the blower to the lamp housing.
3 Make sure the blower gasket remains in position on the lamp housing. The gasket must be in
place before installing a new blower.
