Our projector uses LCD (Liquid Crystal Display) panels. These very
sophisticated panels contain 786,432 pixels ( x RGB) TFTs (Thin Film
Transistors).
As with any high technology electronic equipment such as large
screen TVs, video systems and/or video cameras, there are certain
acceptable tolerances that the equipment must conform to. This unit
has some inactive TRTs within acceptable tolerances which may result
in illuminated or inactive dots on the picture screen.

IMPORTANT SERVICE SAFETY NOTES

n 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.

I .

.

. .

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:

l Plug the AC cord directly into a 120~volt AC outlet,

(Do not use an isolation transformer for this test).

l Using two clip leads, connect a 1.5k ohm, 10 watt

resistor paralleled by a 0.15uF 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.

SAFETY NOTICE

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 “A”
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams.
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.

For continued protection,

AVIS POUR LA SECURITE

De nombreuses pieces, electriques et mecaniques, dans
les projecteur a LCD presentent des caracteristiques
speciales relatives a la securite, qui ne sont souvent
pas evidentes a vue.
Le degre de protection ne peut pas etre necessairement
augmentee en utilisant des pieces de remplacement
etalonnees pour haute tension, puissance, etc.
Les pieces de remplacement qui presentent ces
caracteristiques sont identifiees dans ce manuel;
les pieces electriques qui presentent ces particularites
sont identifiees par la marque “A” et hachurees dans la
liste des pieces de remplacement et les diagrammes
schematiques. Pour assurer la protection, ces pieces
doivent etre identiques a celles utilisees dans le circuit
d’origine. Cutilisation de pieces qui n’ont pas les memes
caracteristiques que les pieces recommandees par
I’usine, indiquees dans ce manuel, peut provoquer des
electrocutions, incendies ou autres accidents.

Inserting the batteries

Remove the battery cover as shown and insert four AA
size batteries making sure their polarities match the ( + )
and ( -) marks inside the battery compartment.

Notes:
Incorrect use of batteries may cause them to leak or burst.

0

Insert the batteries with the (+) and (-) polarities as indi­cated.
Remove the batteries if the remote control will not be oper­ated for an extended period of time.
Maintain the batteries in a clean condition.
Do not mix different brands of batteries. The life expectancy
of the new batteries will be shortened and the old batteries
may leak.

0

When the batteries have been used up, remove them imme­diately to prevent leakage -and damage. Leaked battery fluid
may irritate the skin. Remove any battery fluid by wiping with
a cloth.
Due to storage conditions and the shelf life of the supplied

CONVERGENCE AND FOCUS,ADJUSTMENT

l 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

Focus adjustment. (Make this adjustment on the white-only screen.)

(4

1. Right-and-left focus adjustment @Y direction) .
Loosen the lock screws “b” and “c” and insert the eccentric screwdriver into the notch and hole ‘lb”. 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.
Top-center-bottom focus adjustment (0X and Z directions).

2 .

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 8Y direction adjustment.
Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.

.

3

Notes :

@ Carefully proceed with the focus adjustment because the adjusting directions are correlated.
@ In adjusting the convergence and focus, do not move the projection lens zoom and focus rings until the end

of all the adjustments.

Convergence adjustment

l 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

0‘ Take 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

l 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 8Z directions.
(3) Finally tighten up the convergence lock screw “d”.

Notes :

@ The eccentric cam is used for convergence adjustment. This means that the cam’s turning and the linear

movement are not always uniform.

@ 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 (Ml9 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 Ml adjust lever.
(5) Looking at the G image on the screen, turn or slide the Ml 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
