IMPORTANT SERVICE SAFETY NOTES (for USA)

Ë Service work should be performed only by qualified service technicians who are

thoroughly familiar with all safety checks and servicing guidelines as follows:

22

22

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.

SAFETY NOTICE

Many electrical and mechanical parts in DLP 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.

WARNING: The bimetallic component has the primary

conductive side exposed. Be very careful in
handling this component when the power is on.

AVIS POUR LA SECURITE

De nombreuses pièces, électriques et mécaniques, dans
les projecteur à DLP 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.

AVERTISSEMENT: La composante bimétallique dispose du

conducteur primaire dénudé. Faire
attention lors de la manipulation de cette
composante sous tension.

UV-RADIATION PRECAUTION (Continued)

Lamp Replacement

Note:

Since the lamp reaches a very high temperature
during units operation replacement of the lamp
should be done at least one hour after the power
has been turned off. (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector

DANGER ! –– Never turn the power on without the
lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.

PRECAUTION POUR LES RADIATIONS UV (Suite)

Remplacement de la lampe

Remarque:

Comme la lampe devient très chaude pendant le
fonctionnement de l’unité, son remplacement ne doit
être effectué au moins une heure après avoir coupé
l’alimentation (pour permettre à la lampe de refroidir).
En installant la nouvelle lampe, s’assurer de ne pas
toucher la lampe (ampoule). Remplacer la lampe en
tenant son réflecteur 2.
[N’utiliser qu’un remplacement d’origine.]

DANGER ! –– Ne jamais mettre sous tension sans
la lampe pour éviter un choc électrique ou des
dommages des appareils car le stabilisateur génère
de hautes tensions à sa mise en route.

Since small amounts of UV-radiation are emitted from
an opening between the exhaust fans, it is recom­mended to place the cap of the optional lens on the
opening during servicing to avoid eye and skin ex­posure.

Comme de petites quantités de radiation UV sont
émises par une ouverture entre les ventilateurs as­pirants, il est recommandé de placer le capuchon
de l’optique optionnelle sur l’ouverture pendant
l’entretien pour éviter une exposition des yeux et la
peau.

Precautions for using lead-free solder

1 Employing lead-free solder

"Main, Key, R/C Receiver(Rear), R/C Receiver(Front), LED, IRIS DRIVE ,PC I/F and Power PWB" of this model
employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service
manuals. The alphabetical character following LF shows the type of lead-free solder.
Example:

L Fa

Indicates lead-free solder of tin, silver and copper.

2 Using lead-free wire solder

When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you
to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening bit,
contact our service station or service ranch in your area.

22

2

22

3 Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder
by 40°C, and as it has poor solder wettabillty, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature
of parts may be excoeded, remove the bit from the PWB as soon as you conurm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum on
and off the power of the bit as required.
if a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

Becareful when replacing parts with polarity indication on the PWB silk.

Descriptions

The DC Light source lamp with parabola reflector.

The condensor lens leads the light generated from the lamp to the end sur­face 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 prop­erly 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 de­pending on the input source.

This lens enlarges and projects the incidend light coming from the DMD.

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.

Insert hexagon wrench
in this direction.

Expansion figure of part A

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.

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.

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.

No. Adjusting point Adjusting conditions Adjusting procedure

The unit has been adjusted optimally at the time of factory shipment. However, if the screen position is deviated or
when exchanging parts, make an adjustment as shown below.

•Turn on the power (lamp on state) and wait for 15 minutes for aging.

• Enter the adjustment process mode with SW2002 (tact switch) on the main unit.

• Select the group to adjust with the DOWN ( " ) key or the UP ( ' ) key on the remote control, and enter the

adjustment item with the ENTER ( ) key on the remote control.

• Select the adjustment item with the DOWN ( " ) key or the UP ( ' ) key on the remote control.

<Cautions for adjustment>

1) Initialization and factory setting

If the initialization S2 or the factory setting S5 of EEPROM is carried out, time for writing the data is necessary.

When the initialization S2 or the factory setting S5 of EEPROM are executed, the OSD display of the adjust­ment process mode disappears, and INPUT 1 is selected after about 15 seconds. Since the OSD display of
the set 2 or the set 5 appears, never turn off the power until this display appears.

2) AUTO adjustment

At the time of AUTO adjustment, do not bring to the no-signal state. (Do not stop the signal.)

Otherwise the adjustment data may be changed or deleted.
