Descriptions
The DC Light source lamp with parabola reflector.
The condensor lens leads the light generated from the lamp to the end sur-
face of the light-tunnel through the IR-cut mirror.
The IR-cut mirror is set in this unit to eliminate the excessive heat by the lamp
energy.
This color filter separates the white light into the 3 colors R,G and B.
A photo-sensor should be set in this unit to detect the transition timing prop-
erly between color filters.
The maximum rotating speed is 9000rpm.
This unit leads the illumination spot to effective area on DMD.
This prism also leads the illumination spot to effective area on DMD and at the
same time leads the reflection lights on the DMD to the projection lens.
This chip turns on and off in projection to each color component per dot de-
pending on the input source.
This lens enlarges and projects the incidend light coming from the DMD.

Adjusting the back focal distance after replacing the projection lens
Note: A piece of temporary tape is attached on the focus ring that comes with the replacement projection lens. Keep
this tape in place until the finish of the adjustment.
(1) Provide a distance of 2.4 m between the set and the screen and adjust the zoom knob to “wide end”.
(2) Adjust the lens shift until the projection lens comes to the same level as the center of the screen.
(3) Detach the optical unit top cover A from behind the projection lens.
(4) Loosen the four hex screws B in the back of the projection lens.
(5) Insert the adjustment screwdriver C (9EVDRIVERZ9000) in the hole D at the back of the lens. Put the center of the
screen in the best focus. (Preferably feed the SXGA signal for 1-dot white crosshatch pattern or 1-dot white dot
pattern on black background.)
(6) Tighten the four hex screws B to the torque of 0.3 Nm (3.06 kgfcm), and apply screw loctite to them.
(7) Peel the temporary tape off the focus ring of the projection lens.
(8) Attach the optical unit top cover A back into position. Finally fix the two screws E and apply screw loctite to them.
Adjusting the mirrors
Make adjustment by the indication territory on the screen to prevent the circumference of the screen from getting
dark because a lighting range deviated.
1. Remove the top body so that the optical unit may be seen. Display white only screen on the screen.
2. Detach the mirror adjustment part cover 1 on the bottom right of the projection lens.
3. Turn three screws with special hexagon wrench (9HPH10XL120) and adjust so that a part of the screen may not
get dark because a lighting range deviated.
4. Mount the adjustment part cover 1.
5. Mount the top panel.

Replacement of the DMD or formatter unit
The DMD may be broken by static electricity. Always wear an earth band before beginning the work.
The contact of the interposer is minute, so pay sufficient attention when handling.
Attachment of DMD
Check of DMD bin voltage
Check the last alphabet of the lowest line of the
rear side of the DMD to attach. (Example: 02026E
→ bin voltage "E")
Setting of the formatter unit DMD bin voltage
Set S9101 and S9102 to the position of the PWB silk
with the same alphabet as the DMD bin voltage.
Insert the DMD into the interposer
Spray the interposer and the DMD with air.
While widening the claws of the interposer, insert the DMD as if it is dropped in.
Note: If the DMD is pressed in, the interposer is ground and shaving generated by grinding may cause the contact
failure. Do not insert it forcibly.
Joint of DMD and the unit
Wipe to clean the contamination of the PWB contacting part (gold plating part) with ethanol.
Set the position of the interposer with the DMD attached to the unit PWB, and then cover the clamp.
Sandwich the unit PWB with the backer plate from the reverse side of the unit PWB and tighten with screws.
At this point, firstly tighten the screws temporarily, and retighten them diagonally.
The tightening torque is 1.13 N-m (11.5 kgfcm)
Mount the radiator fin and secure it with a clip.

When the DMD unit has been replaced
Note: DMD chip and Formatter PWB are supplied at the same time, and an exchange only with DMD isn't done.Refer
to "REMOVING OF MAJOR PARTS" when exchanging Formatter PWB.
There is no need to readjust the back focal distance of the projection lens. If focusing is noticeably poor, however,
make this readjustment.
(1) Provide a distance of 2.4 m between the set and the screen.
(2) Adjust the lens shift until the projection lens comes to the same level as the center of the screen.
(3) Detach the optical unit top cover A from behind the projection lens.
(4) Loosen the four hex screws B in the back of the projection lens.
(5) Adjust the zoom knob at the front of the projection lens to "tele end" and ensure good focusing.
(6) Then adjust the zoom knob at the front of the projection lens to "wide end".
(7) Insert the adjustment screwdriver C (9EVDRIVERZ9000) in the hole D at the back of the lens. Put the center of
the screen in the best focus. (Preferably feed the SXGA signal for 1-dot white crosshatch pattern or 1-dot white
dot pattern on black background.)
(8) Move the zoom knob from "wide end" back to "tele end" and see if focusing is ensured. If not, repeat the above
steps (5), (6) and (7) until the best focus is achieved.
(9) Tighten the four hex screws B to the torque of 0.3 Nm (3.06 kgfcm), and apply screw loctite to them.
(10) Attach the optical unit top cover A back into position. Finally fix the two screws E and apply screw loctite to them.
