Lamp Module - InFocus 900 Series Service Manual

Removing and replacing the lamp module
The lamp module (LP920, IOpen 920: SP-LAMP-IO9; LP925, LP930: SP-LAMP-LP9) provides a
spectrum-balanced, concentrated, and carefully focused light beam for the optical engine. It is located at
the rear of the projector inside the lamp housing which is a part of the optical engine. The lamp module
fastens to the lamp house with three captive screws. Replacing the lamp module with a new one
automatically resets the lamp hour counter in the projector.
WARNING Allow the projector to cool before removing the lamp module. The lamp module becomes very hot
when the projector is in use. Operating temperatures inside the lamp housing are high enough to
cause burns. Avoid touching any portion of the lamp module that is located in the light path. Oils from
your fingers can cause smudges and uneven heating of lamp surfaces, resulting in decreased image
quality and premature lamp failure. If the lamp is ruptured or the lamp module is cracked or damaged,
be careful of quartz or glass fragments that could cause personal injury.
1 Remove the rear bezel (see page 43).
2 Use a #2 Phillips driver to loosen the three captive screws that fasten the lamp module to the
lamp housing. You don't need to remove the screws.
3 Grasp the handle on the lamp module and pull the module out of the lamp housing.
