This SHARP projector uses LCD (Liquid Crystal Display) panels. These
very sophisticated panels contain 1,310,720 pixels ( ✕ RGB) TFTs
(Thin Film Transistors). As with any high technology electr onic
equipment such as lar ge scr een 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 pictur e screen. This
will not affect the picture quality or the life expectancy of the unit.

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
1
Reflector
2
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.
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
CLMPF0064DE01/02 or BQC-XGV10WU/1 rated
100V/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.
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 ex-
posure (Fig. 1).
Note: Please obtain a lens cap before servicing a
model XG-V10WE that is received without
one.

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-V10WE
AN-SD1E/S422E
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.

Adjust the above settings in the range of 0-4. When changing each setting from the initial setting of 2, however,
the 1280 x 1024 dot display area will have a fewer number of lines.
Example 1 : When the R-CNV-H setting is changed from 2 (initial) to 4, the number of lines will be from 1280 to
1278.
Example 2 : When the R-CNV-H, G-CNV-H and B-CNV-H settings are changed to 3, 3 and 4, respectively, the
display will be 1278 x 1024 lines. But when the above settings are switched to 2, 2 and 3, respectively, the display will be 1279 x 1024 lines.
Preferably keep each setting as close to 2 as possible.
