This SHARP projector uses LCD (Liquid Crystal Display) panels. These very sophisticated panels contain 786,432 pixels ( × RGB) TFTs (Thin Film Transistors). As with any high technology electronic equipment such as large screen TVs, video systems and video cameras, there are certain acceptable tolerances that the equipment must conform to.

Specifications are subject to change without notice.

This unit has some inactive TFTs within acceptable tolerances which may result in illuminated or inactive dots on the picture screen. This will not affect the picture quality or the life expectancy of the unit.

NOTE TO SERVICE PERSONNEL

UV-RADIATION PRECAUTION

234567890123456789012345678901212345678901234

The light source, metal halide lamp, in the LCD projector emits small amounts of UV-Radiation.

AVOID DIRECT EYE AND SKIN EXPOSURE.

To ensure safety please adhere to the following:

1. Be sure to wear sun-glasses when servicing the projector with the lamp turned “on” and the top enclosure removed.

XG-P10XE

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

2. Do not operate the lamp outside of the lamp housing.

3. Do not operate for more than 2 hours with the enclosure removed.

UV-Radiation and Medium Pressure Lamp Precautions

1. Be sure to disconnect the AC plug when replacing the lamp.

2. Allow one hour for the unit to cool down before servicing.

3. Replace only with same type lamp. Type CLMPF0064DE11 or BQC-XGP10XE/1 rated 85V/ 200W.

4. The lamp emits small amounts of UV-Radiation, avoid direct-eye contact.

5. The medium pressure lamp involves a risk of explosion. Be sure to follow installation instructions described below and handle the lamp with care.

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.

Since small amounts of UV-Radiation are emitted from an opening between the duct cover and the lamp housing, it is recommended to place the LENS CAP on the opening during servicing to avoid eye and skin exposurem (Fig. 1).

Note: Please obtain a lens cap before servicing a

model XG-P10XE that is received without one.

Usage Guidelines

Cautions Concerning the Laser Pointer

The laser pointer on the remote control emits a laser beam from the laser pointer window. This is a Class II laser which may impair your sight if directed into the eyes. The two marks shown on the left are caution labels for the laser beam.

• Do not look into the laser pointer window or shine the laser beam on yourself or others. (The laser beam used in this product is harmless when directed onto the skin. However, be careful not to project the beam directly into the eyes.)

• Always use the laser pointer at temperatures between + 5°C and + 40°C.

• Use of controls or adjustments, or performance of procedures other than

those specified herein may result in hazardous radiation exposure.

LAMP MAY RUPTURE.

RUPTURE POSSIBLE DE LA

Caution Concerning the Lamp Unit

Potential hazard of glass particles if lamp ruptures. Please have Sharp Authorised LCD Projector Dealer or Service Centre replace lamp if rupture occurs.

Cautions Concerning the Setup of the Projector

For minimal servicing and to maintain high image quality, SHARP recommends that this projector be installed in an area free from humidity, dust and cigarette smoke. If the projector is used in these environments, the lens and filter will need to be cleaned (or the filter replaced) more often, and internal cleaning may become necessary. As long as the projector is regularly cleaned, use in these environments will not reduce the overall operation life of the unit. Internal cleaning should only be performed by a Sharp Authorised LCD Projector Dealer or Service Centre.

Notes on Operation

• 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.

• Allow at least 10 cm of space between the cooling fan (exhaust vent) and the nearest wall or obstruction.

• 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 power cord from the wall outlet and wait at least 10 minutes. Then turn on the power by plugging the power cord back in. This will return the projector to the normal operating condition.

CONVERGENCE AND FOCUS ADJUSTMENT

» Start the convergence and focus adjustments with the top cabinet and the LCD cover

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

(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-colour and the relevant colour. (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".

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.

Replacing the LCDs

With the top cabinet removed

(1)Disconnect the LCD flat cable from the output PWB connector. (2)Remove the lock screws "b" and "c". Detach the R/B adjusting plate or the G adjusting plate together with the LCD

panel. (3)Separate the LCD panel from the adjusting plate. (4)Mount a new LCD panel in the reverse order of the above steps (1), (2) and (3).

~ Readjust the convergence and focus. Note that the G LCD panel needs no convergence adjustment and has

a small adjustment range in the Z direction.

Adjusting the optical axis of the mirrors (M1, 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 M1 adjust lever. (5)Looking at the G image on the screen, turn or slide the M1 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 image.

Make sure there is no eclipse.
