• Lamp has been used for over 1,900

hours.

• Lamp has been used for over 2,000

hours.

• Purchase a replacement lamp unit

(lamp/cage module) of the current
type BQC-XGC40XU/1 from your
nearest Sharp Authorised LCD
Projector Dealer or Service Centre.

• Replace the lamp. If you wish, you

may have the lamp replaced at
your nearest Sharp Authorised
LCD Projector Dealer or Service
Centre.

The LAMP REPLACEMENT
indicator lights up red, and “LAMP”
and “    ” will flash in yellow in the
lower-left corner of the picture.

A significant deterioration of the
picture and colour quality occurs.

The power will automatically turn
off and the projector will enter
standby mode.

“LAMP” and “    ” will flash in red in
the lower-left corner of the picture,
and the power will turn off.

The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ-
ment. It is recommended that the lamp be replaced after 1,900 cumulative hours of use or when you notice a
significant deterioration of the picture and colour quality. The lamp usage time can be checked with the On-screen
Display.

• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.

• As the usage environment can vary significantly, the projector lamp may not operate for 2,000 hours.

1. While holding down the “ENTER”, “ADJ.

"

” and “ADJ.

|

” keys on the set at the same time, turn on the main

power switch (located side the AC inlet).

2. Now the total lamp timer is reset to zero. “000H” appears on the screen.

1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus.
2. Replace the LCD panels with new ones. But until the focus has been completely readjusted, be careful not

to change the projection distance between the set and the screen, nor to move the projection lens focus
and zoom rings.

Note:

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 the focus.

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

projection distance between the set and the screen, nor to move the projection lens focus and zoom rings.

3. If the projection distance has been changed or the projection lens readjusted, repeat the above steps 1 and

2.

1. Adjustment in  

θ

X and Z directions .

Loosen the lock screw "a" and insert an eccentric screwdriver into the notch and hole "a".  Turn the screwdriver
until the top, center and bottom on the screen get into focus. In adjusting this top-to-bottom focus, tighten
the lock screws "b" and "c" to fix the 

θ

Y direction adjustment.

First get the right and left halves in balance.  Then improve the accuracy while making the adjustment 2
below.

2. Adjustment in 

θ

Y direction

Temporarily tighten the lock screw "a" and loosen the lock screws "b" and "c". Insert the eccentric screwdriver
into the notch and hole "c" for adjusting in the 

θ

Y direction on the top of the screen. Insert the eccentric

screwdriver into the notch and hole "b" for adjusting in the 

θ

Y direction on the bottom of the screen.

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.

1. Take the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is

wider 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.

»

Use a crosshatch pattern signal for this adjustment.
Make the adjustment just for the G-LCD and the relevant colour.

1. Loosen the convergence lock screw "d".
2. Adjustment in Y and 

θ

Z directions

Put a hex wrench in the Y and 

θ

Z direction adjustment zone.

3. Adjustment in X direction

Put an eccentric cam adjusting wrench in the X direction adjustment zone.
