Precautions in replacing the DMD chip
Note: Be careful not to allow dust and fingerprint

on the cover glass of DMD chip and prism
surface of optical engine.

1. Tighten 4 screws gradually from opposite sides

to fix the backer plate M, stud spring M, and stud
M. To perform this step, press the shadow part
of the stud spring M to the formatter PWB with
your finger.

2. If something shade appears on the projection

screen like Fig1, release 2 screws on mirror
adjusting plate and move that plate to adjust
illumination area of DMD chip.

Before connecting the formatter PWB to the optical engine, take the following steps. Look at the voltage rank marking

that is on the DMD itself. Referring to this marking, set the DIP switches on the formatter PWB. And connect this PWB

to the optical engine. Wrong settings will adversely affect the system performance.

DMD Setting: Check the last alphabet character shown in 

1

, and set the two switches shown in

 according to the

configurations shown in

.

Set the formatter PWB switches according to the Bin voltage shown on the back face of the DMD.

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.)

You need to reset the lamp timer every time you replace the lamp and confirm it is reset on the

“Lamp Timer” menu.

Confirm that the POWER indicator
illuminates red.
