Function
Light source. DC-driven high-pressure mercury vapor lamp.
Used to absorb ultraviolet and infrared rays.
Used to let the source light through the color filter and to
separate it into R, G and B colors.
Used to make for uniform light beams.
Used to collect the light from the rod lens into the DMD
chip.
Used to reflect the light from the relay lenses against the
DMD chip.
Used to introduce the light from the reflector over the effec-
tive surface of the DMD chip. When the micromirror gets
tilted (ON) as specified, the reflected light is guided to the
projection lens.
Used to turn on and off the micromirror in response to the
ratio of color components at each dot and thus to reflect the
incoming light accordingly.
Used to enlarge the light from the DMD chip and to get the
light projected on the screen.

Caution when repairing without top cabinet
To repair this set without top cabinet, attach the left side body beforehand. (Since the exhaust heat gets in around the
set and the temperature sensor detects it giving the TEMP error and the lamp goes off.)
