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 TFTs 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 gu_idelines as follows:

Use an AC voltmeter with sensitivity of 5000 ohm

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.

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 0.15yF capacitor in parallel between all exposed metal cabinet parts and earth ground.

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.

CONNECT TO KNOWN EARTH GROUND

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. 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 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. L’utilisation 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.

Cautions:

l The exhaust vent, the lamp cage cover and adjacent areas may be extremely hot during

projector operation. To prevent injury, do not touch these areas until they have sufficiently cooled.

l Allow at least 4” (10 cm) of space between the cooling fan (exhaust vent) and the other

nearest wall or obstruction.

l If the cooling fan becomes obstructed, a protection device will automatically turn off the

projector lamp. This does not indicate a malfunction. Remove the projector plug from the wall outlet and wait 10 minutes. Then turn on the power by plugging the cord back in. This will return the projector to its normal mode.

CONVERGENCE AND FOCUS ADJUSTMENT

Start the convergence and focus adjustments with the top cabinet and the signal shield removed but the power on. Use the remote control to adjustthe image. Take the following procedures.

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 @Y direction) .

Loosen the lock screws “b” and “c” and insert the eccentric screwdriver into the notch and hole “b” or “c”.

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 (0X and Z directions).

Loosen the lock screws “a” and “c” and insert the eccentric screwdriver into the notch and hole “a” and “cl’. Turn the screwdriver until the top, center and bottom on the screen get into focus. top-to-bottom focus, temporarily tighten the lock screw “b” to fix the 0Y direction adjustment.

3. Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.

Notes :

@ Carefully proceed with the focus adjustment because the adjusting directions are correlated.

@I 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

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

l 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 0Z directions. (3) Finally tighten up the convergence lock screw I’d”.

In adjusting this

XG-E3500U

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.
