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.

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 “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.

CONVERGENCE AND FOCUS ADJUSTMENT

» Place the set in the ceiling-mounted position, open the maintenance door, and start the

convergence and focus adjustments. Make sure the settings are complete and then turn on the power. For adjusting the image, use the remote controller. Take the following adjustment 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".

XG-V10XU

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.

1. Adjusting the mirror optical axis

The optical axis must be readjusted to correct possible eclipse that occurs with the R, G or B LCD panel. This readjustment is usually required when an optical part in the optical mechanism has been replaced, and may be needed when a LCD panel has been replaced.

1. Disconnect the LCD flat cable.

2. Get the lamp on. Be sure to start the cooling fan too.

(Eclipse with the R LCD panel: Screen edges appearing in cyan)

3. Loosen the lock screws of the M5 adjusting lever.

4. Watching the image on the screen, turn or slide the M5 adjusting lever until the eclipse disappears from the screen. Now tighten up the lock screws.

(Eclipse with the G LCD panel: Screen edges appearing in magenta)

3. Loosen the lock screws of the M3 adjusting lever.

4. Watching the image on the screen, turn or slide the M3 adjusting lever until the eclipse disappears from the screen. Now tighten up the lock screws.

(Eclipse with the B LCD panel: Screen edges appearing in yellow)

3. Loosen the lock screws of the M6 adjusting lever.

4. Watching the image on the screen, turn or slide the M6 adjusting lever until the eclipse disappears from the screen. Now tighten up the lock screws.

2. Adjusting the orientation of polarizer

The contrast must be optimized when the polarizer or an optical mechanism part has been replaced.

1. Turn on the power.

2. If the background is blue, clear the screen and get it black.

3. Loosen the two lock screws of the polarizer (two for each plate).

4. Press the heads of the lock screws in the arrow directions until the onscreen contrast becomes best. Finally tighten up the lock screws.

3. Adjusting the PBS

This adjustment may be required when the optical mechanism has been disassembled. Colors uneven on the right and left halves onscreen can be corrected here. Usually there is no need to make this adjustment. It is enough to have the lamp adjusting groove in alignment.

1. Turn on the power.

2. Loosen the PBS lock screw.

3. Feed a white-only signal, or call the process mode and get the screen white only.

4. Put the eccentric screwdriver (9EQDRiVER-NV1A) in the PBS adjusting groove.

5. Watching the image on the screen, turn the eccentric screwdriver until the right-and-left colors onscreen become most even. Finally tighten up the lock screw.

4. Adjusting the lamp optical axis

The lamp optical axis is optimized to obtain the best color evenness and brightness. Usually there is no need to make this adjustment because the replacement lamp unit (BQC-XGV10WU/1) has been delivered factory-adjusted.

1. Turn on the power.

2. Loosen the three lamp lock screws.

3. Feed a white-only signal, or call the process mode and get the screen white only.

4. Put the eccentric screwdriver (9EQDRiVER-NV1A) in the lamp adjusting groove.

5. Watching the image on the screen, turn the eccentric screwdriver until the right-and-left colors onscreen become most even. Finally tighten up the lock screws.
