CAUTIONS BEFORE STARTING SERVICING
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper
grounding treatment as required.
Many screws are used inside the unit. To prevent missing, dropping, etc. of the screws, always use a magnetized
screwdriver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care
of the tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used
improperly, the screw holes will be easily damaged and the parts can not be fixed.

following steps.)
4. Mount a new panel on the XY shifting plate with the
Z rotation plate placed between them. (Use L upper
and lower adjustment screws.) At this time, fix them so
that two holes on the panel lower side are matched
with the holes on the Z rotation plate.
5. Mount the Z rotation plate on the holder support.
(Use S adjustment screws.) Tighten the S adjustment
screws lightly.
3-14-1. Panel Replacement and Adjustment

< Panel adjustment procedures >
– carried out with a cross hatch signal (RGB input)
received.
(1) Panel focus adjustment
– carried out with a single color (panel color replaced)
status.
1. Shift the Z rotation plate by holding its handles
located on the upper sides with fingers or a long-nose
pliers, etc. and adjust to obtain the best focus at the
whole screen. At this time, adjust the screen center
focus by shifting the Z rotation plate entirely back
and forth, the left/right screen focus balance by
shifting the rotation plate to left/right rotation
directions and the upper/lower screen focus balance
by shifting it to upper/lower rotation directions.

2. Tighten the S adjusting screws with a wrench for
servicing and fix the Z rotation plate. (Refer to Fig. 1-
3-17.) If the focus adjusted is upset when fixing,
loosen the S adjusting screws and perform the
adjustment in step 1 again.
Fig. 1-3-17 Service wrench
3. Repeat the steps 1 and 2 until the Z rotation plate is
fixed in the best focus condition. Finally, fix the Z
rotation plate perfectly by tightening the S adjusting
screws further with a long-nose plier, etc.
< Holder fixing >
1. Apply screw lock to the S adjusting screws.
2. Fix the Z rotation plate and the holder support, and
the Z rotation plate to the XY shifting plate by using
a silicone bond at the appropriate locations.
3-14-2. Mirror Adjustment Procedures
(After polarizing plate replacement)
1. Loosen screws fixing three mirror holder (WM, RM,
BM).
WM fixing screw
(2) Picture element adjustment
(Convergence adjustment)
– Superimposing pictures on R and B panels with a
picture on G panel.
1. Loosen the upper and lower L adjusting screws fixing
the panel.
2. Shift the XY shifting plate by holding its upper
portion with fingers or a long-nose plier, etc. and
adjust to superimpose the picture on the panel
replaced on that of the G panel.
For the relation between the picture and the XY
shifting plate shifting directions, the picture shifts to
the left when the XY shifting plate shifts to the left
seeing from the incident side of the panel (the picture
shifts to the right when the XY shifting plate shifts to
the right direction.), and the picture shifts to the lower
direction when the XY shifting plate shifts to the
upper direction (the picture shifts to the upper
direction, when the XY shifting plate shifts to the
lower direction.).
3. Fix the panel by tightening the upper/lower L
adjusting screws with a wrench for servicing. If a
focus is upset when fixing the panel, loosen the
upper/lower L adjusting screws and perform the step 2
again.
4. Repeat the steps 2 and 3 until the panel is fixed with
the picture superimposed in the best condition.

2. Set G single color screen. Move the WM fixing screw
along the long hole and fix it where the upper and
lower edges of the screen does not show the dark
band.
3. Set R single color screen. Fix the RM fixing screw in
the same way as shown in step 2.
4. Set B single color screen. Fix BM fixing screw in the
same way as shown in step 2.
5. Apply screw lock to each fixing screw. (For the screw
lock position, refer to the figure shown below.)

1. Lay the unit in a dark room and input all white 50% signal, video 10-stairstep signal or RGB 16-stairstep
signal.
2. Affix the standard white board WS-2 on the top center of screen, or suspend it adjacent to the screen
from above.
3. Set the color luminance meter (BM-5) with more than 30 min. heat-run operation performed, so that color
temperature on the WS-2 can be measured.
4. Measure the color temperature by using the BM-5 and adjust with W03 and W05 in the adjustment menu
to obtain the value within the range of X = 0.285 ± 0.01 and Y = 0.310 ± 0.01.

4. Place TLP450/451/650/651 to be adjusted horizontally on a flat table and click “0” of keystone format
(Deg) on the menu and store the data at the horizontal position. (Refer to Fig. 1.)
5. Place TLP450/451/650/651 to be adjusted on a table with 30 degrees slanted and its projection lens
directed upward. Then click “+30” of keystone format (Deg) on the menu and store the data of +30
degrees position. (Refer to Fig. 2.)
6. Place TLP450/451/650/651 to be adjusted on a table with 30 degrees slanted and its projection lens
directed downward. Then click “–30” of keystone format (Deg) on the menu and store the data of –30
degrees position (Refer to Fig. 3.). At this time, the data is written on the flash ROM of the TLP450/
451/650/651.
7. After heat-running for more than 1 hour with the power turned on, place TLP450/451/650/651 horizontally
and click “0 (High-temp)” of keystone format (Deg) to save the horizontal position data at high temperature.
8. Stretch the height adjusting legs on the front side of TLP450/451/650/651 fully, turn on the projector and
start projecting on the screen.
Adjust the focus roughly and push the automatic keystone button on the remote controller. Check to see
the image projected is more rectangular with less trapezoidal in comparison with the shape before
pushing the keystone button.
