Remove And Replace The Optical Engine - Toshiba TDP-MT8 Service Manual

Remove and Replace the Optical Engine

The optical engine fastens to the bottom case. The body of the engine fastens to the optical engine
mounting bracket, while the light tunnel fastens directly to the bottom case near the lamphouse. The
engine comprises all parts in the light path including the:
♦
DMD – produces the image by reflecting wanted pixels through the projection lens and discarding
unwanted pixels by reflecting them to a "dump light" area inside the engine.
♦
DMD driver board – formats the image signal for interpretation by the DMD
♦
Color wheel – provides colors for the DMD to use in image production
♦
Light tunnel – conducts focused light from the lamp module to the DMD
♦
Photodiode – reads color wheel rotation to maintain proper synchronization with the DMD and allow
accurate color reproduction
♦
Projection lens – focuses or changes the size of the image produced by the DMD
