Remove And Replace The Optical Engine - InFocus LP630 Service Manual

Remove and Replace the Optical Engine

The optical engine (525-0038-xx) produces the projected image by directing focused light from the lamp
module through three polysilicon LCDs. The optical engine is located beneath the controller ECA and
includes the lens and lamp housing.
WARNING Allow the projector to cool before removing the lamp module. The lamp module becomes very hot
when the projector is in use. 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 following items:
Top case (see page 13)
Controller ECA (see page 16)
2 Loosen the two captive screws that fasten the lamp to the lamp housing.
3 Grasp the lift tabs and lift the lamp out of the projector. Set the lamp aside.
