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:

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.

XV-Z12000

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

2. [Use original replacement only.]

Lamp

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.]

Lampe

Reflecteur

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.

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.

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.

XV-Z12000

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.
