IMPORTANT SERVICE SAFETY NOTES
Ë Service work should be performed only by qualified service technicians who are thoroughly
familiar with all safety checks and servicing guidelines as follows:
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the projector to the user, perform
the following safety checks:
1. Inspect lead wires are not pinched between the
chassis and other metal parts of the projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
current leakage in the following manner:
» Plug the AC cord directly into a 120-volt AC outlet,
(Do not use an isolation transformer for this test).
» Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in parallel
between all exposed metal cabinet parts and earth
ground.
» Use an AC voltmeter with sensitivity of 5000 ohm per
volt., or higher, sensitivity to measure the AC voltage
drop across the resistor (See Diagram).
» All checks must be repeated with the AC plug
connection reversed. (If necessary, a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any reading of 0.3 volts RMS (this corresponds to
0.2 milliamp. AC.) or more is excessive and indicates
a potential shock hazard which must be corrected
before returning the unit to the owner.
Many electrical and mechanical parts in LCD Projector
have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by “å”
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams. For continued protection,
replacement parts must be identical to those used in the
original circuit. The use of a substitute replacement parts
which do not have the same safety characteristics as
the factory recommended replacement parts shown in
this service manual, may create shock, fire or other
hazards.
AVIS POUR LA SECURITE
De nombreuses pièces, électriques et mécaniques, dans
les projecteur à LCD présentent des caractéristiques
spéciales relatives à la sécurité, qui ne sont souvent
pas évidentes à vue.
Le degré de protection ne peut pas être nécessairement
augmentée en utilisant des pièces de remplacement
étalonnées pour haute tension, puissance, etc.
Les pièces de remplacement qui présentent ces
caractéristiques sont identifiées dans ce manuel;
les pièces électriques qui présentent ces particularités
sont identifiées par la marque “å” et hachurées dans la
liste des pièces de remplacement et les diagrammes
schématiques. Pour assurer la protection, ces pièces
doivent être identiques à celles utilisées dans le circuit
d’origine. L’utilisation de pièces qui n’ont pas les mêmes
caractéristiques que les pièces recommandées par
l’usine, indiquées dans ce manuel, peut provoquer des
électrocutions, incendies ou autres accidents.

CONVERGENCE AND FOCUS ADJUSTMENT
» Start the convergence and focus adjustments with the top cabinet and the LCD covers
(Top/Bottom) removed but the power on. Use the remote control to adjust the image.
Take the following procedures.
1. Focusing the projection lens
(A) Replacing all the 3 LCD panels
1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus.
2. Replace the panels with new ones. But until the focus has been completely readjusted, be careful not to
change the distance between the set and the screen, nor to move the projection lens focus and zoom
rings.
If the focus is readjusted with a different positional relation, the relation between the projection distance
and the screen size is affected. In other words, a short-distance image (40 WIDE, for example) may get
out of the focus range, or a long-distance image (300 WIDE, for example) may come out of focus.
(B) Replacing 1 or 2 of the 3 LCD panels
1. In adjusting the focus after replacement of one or two LCD panels, project an image on the screen and turn
the projection lens focus ring to get the non-replaced LCD panel into focus.
2. But until the focus has been completely adjusted for the new LCD panels, be careful not to change the
distance between the set and the screen, nor to move the projection lens focus and zoom rings.
(If the distance has been changed or the projection lens readjusted, repeat the above steps 1 and 2.)
2. Adjusting the G-LCD panel
(A) Focus adjustment. (Make this adjustment on the white-only screen.)
1. Right-and-left focus adjustment (θY direction) .
Loosen the lock screws "b" and "c" and insert the eccentric screwdriver into the notch and hole "b". Turn
the screwdriver until the right and left halves on the screen get into focus.
First get the right and left halves in balance. Then improve the accuracy while making the adjustment 2
below.
2. Top-center-bottom focus adjustment (θX and Z directions).
Loosen the lock screws "a" and "c" and insert the eccentric screwdriver into the notch and hole "a" or "c".
Turn the screwdriver until the top, center and bottom on the screen get into focus. In adjusting this top-tobottom focus, temporarily tighten the lock screw "b" to fix the θY direction adjustment.
3. Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.
Notes :
1 Carefully proceed with the focus adjustment because the adjusting directions are correlated.
2 In adjusting the convergence and focus, do not move the projection lens zoom and focus rings until the end
of all the adjustments.
(B) Convergence adjustment
» The G-LCD panel has no convergence adjustment mechanism. Use this panel as convergence adjustment
reference.
3. B-LCD panel adjustment (the same for the R-LCD panel)
(A) Focus adjustment
» T ake the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is small
in the Z direction. If the convergence is quite different between the B-LCD and G-LCD panels, roughly adjust
the convergence first and then the focus.
(B) Convergence adjustment
» Use a crosshatch pattern signal for this adjustment.
Make the adjustment just for the G-color and the relevant color.
(1) Loosen the convergence lock screw "d".
(2) With the G-LCD panel’s screen center as reference, adjust the B-LCD panel in the X, Y and θZ directions.
(3) Finally tighten up the convergence lock screw "d".
20
Notes :
1 The eccentric cam is used for convergence adjustment. This means that the cam’s turning and the linear
movement are not always uniform.
2 This model is not equipped with the LCD image adjustment mechanism. This is because the dichroic prism
is used for image formation. When the LCD panels all get into the best focus, the images are almost
completely converged.

Replacing the LCDs
With the top cabinet removed
(1)Disconnect the LCD flat cable from the output PWB connector.
(2)Remove the two screws of the LCD cover.
(3)Remove the lock screws "b" and "c". Detach the R/B adjusting plate or the G adjusting plate together with the LCD
panel.
(4)Separate the LCD panel from the adjusting plate.
(5)Mount a new LCD panel in the reverse order of the above steps (1), (2), (3) and (4).

Adjusting the optical axis of the mirrors (M1, M5 and M6)
The optical axis must be readjusted if an eclipse happens with the R. G or B mirrors. Generally speaking,
this adjustment is needed when any of the internal optical components has been replaced.
Adjustment procedure required when any of the panels has been replaced or the convergence has been
adjusted
(1)Disconnect the flat cables of all the LCD panels.
(2)Let the lamp light up.
(3)To adjust the G mirror, shield the R and B mirrors with shielding plates (You can use a business card or the like to
block the light).
(4)Loosen the lock screw of the M1 adjust lever.
(5)Adjust the color discrepancy on the screen by turning the screws A and B.
(6)To adjust the R mirror, shield the G and B mirrors and adjust the M5 adjust lever. For the B mirror, shield the R and
G mirrors and adjust the M6 adjust lever.
(Take the same steps 4 and 5 above.)
(7)Remove all the shielding plates to have a white image.
Make sure there is no eclipse.

Fix the R-, G- and BPHASE settings all to 4.
» Feed the SVGA gradation pattern single-color sig-
nal and make sure that there is no difference in
brightness between adjacent vertical lines. If there
is a difference, make fine adjustment by choosing
the following subjects.
R2-GAIN for red
G2-GAIN for green
B2-GAIN for blue.
» Using the control switches or the remote controller
buttons, make sure that the “OUTPUT 3” characters
are not blurry and there is no ghost image. If such
blur or ghost occurs, finely adjust the setting in the
range of 7~9.

2-1. Oscilloscope range setting
Set the range to DC 1V/div. and 5µs/div.
2-2. Input signal
Feed the SVGA 800x600 60Hz gradation waveform signal.
2-3. Adjusting and checking the level settings
1)Press the S5001 key to call the process mode.
2)Adjust the SH-PHASE setting on the "OUTPUT 3" menu until the "OUTPUT 3" characters are not blurry any
longer.
3)Connect a oscilloscope to TP2. Adjust the BRIGHT setting of "OUTPUT 2" to have the black level of the signal
at 1.7V.
4)Adjust the ROS setting on the A/D menu until the voltage at the positive pole of C64 or pin (2) of IC1 1 becomes
1.7V .
5)Adjust the GOS setting on the A/D menu until the voltage at the positive pole of C57 or pin (2) of IC10 becomes
1.7V .
6)Adjust the BOS setting on the A/D menu until the voltage at the positive pole of C50 or pin (2) of IC9 becomes
1.7V.
7)Make sure the GAIN setting on the A/D menu is 163.
8)Connect the oscilloscope to TP1. Adjust the R-D setting on the A/D menu until the white top level of the signal
becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)
9)Connect the oscilloscope to TP3. Adjust the B-D setting on the A/D menu until the white top level of the signal
becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)
10) Connect the oscilloscope to TP2. Adjust the G-D setting on the A/D menu until the white top level of the signal
becomes 3.6V. (Make sure that both the black and white graduations are visible clearly.)
