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.
WARNING: The bimetallic component has the primary
conductive side exposed. Be very careful in
handling this component when the power is on.
AVERTISSEMENT: La composante bimétallique dispose du
conducteur primaire dénudé. Faire
attention lors de la manipulation de cette
composante sous tension.

CONVERGENCE AND FOCUS ADJUSTMENT
» Start the convergence and focus adjustments with the top cabinet and the LCD cover
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".

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.

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)Looking at the G image on the screen, turn or slide the M1 adjust lever until the eclipse on the screen disappears.
Tighten up the screw.
(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.
