Troubleshooting

Replacing the Lamp

Replace the lamp with a new one if a message displayed on the projected image or the LAMP/
COVER indicator notifies you to replace the lamp (pages 33, 34).
Use an LMP-C240 projector lamp (not supplied) for replacement.

Caution

• The lamp remains hot after the projector is

turned off. If you touch the lamp, you may

burn your finger. When you replace the
lamp, wait for at least an hour after
turning off the projector for the lamp to
cool sufficiently.

• Do not allow any metallic or inflammable
objects into the lamp replacement slot after
removing the lamp, otherwise it may cause
electrical shock or fire. Do not put your
hands into the slot.

Notes

• If the lamp breaks, contact qualified
Sony personnel. Do not replace the lamp
yourself.

• When removing the lamp, be sure to pull it
out straight, by holding the designated
location. If you touch a part of the lamp other
than the designated location, you may be
burned or injured. If you pull out the lamp
while the projector is tilted, the pieces may
scatter if the lamp breaks any may cause
injury.

1 Turn off the projector, and disconnect

the AC power cord from a wall outlet.

2 When the lamp has cooled

sufficiently, open the lamp cover by
loosening 3 screws.

You can remove the lamp cover for a
while when installing on the ceiling.
Take care to prevent the lamp cover from
falling down, as it is not fixed.
Do not apply pressure to the lamp cover
while it is open.

Caution

Disposal of the used lamp

For the customers in the USA

Lamp in this product contains mercury.
Disposal of these materials may be
regulated due to environmental
considerations. For disposal or
recycling information, please contact
your local authorities or the
Telecommunications Industry
Association (www.eiae.org).

5 Close the lamp cover and tighten the

3 screws.

Note

Be sure to install the lamp and Lamp cover
securely as it was. If not, the projector
cannot be turned on.

Replacing the Lamp

Cleaning the Air Filter

When a message appears on the projected image, clean the air filter (page 34).
If the dust cannot be removed from the air filter even after cleaning, replace the air filter with
a new one. For details on a new air filter, consult with qualified Sony personnel.

Caution

If you neglect to clean the air filter, dust may accumulate, clogging it. As a result, the
temperature may rise inside the unit, leading to a possible malfunction or fire.

1 Turn off the projector, and disconnect

the AC power cord from the AC outlet.

2 Draw out the air filter cover.

Note

If you remove the air filter cover when
power is turned on and the AC power cord

Projection Distance and Lens Shift Range

The following describes the projection distance and height from lens center to bottom of screen
by each projected screen size.
The projection distance is the distance between the front of the lens and the surface of the
projected image.
Height H is the height from the bottom of the projected image (top for ceiling mount) to A
(determined by drawing a perpendicular line from lens center to projected image surface). For
this unit, the same projection distance calculations apply to both floor and ceiling installation.

Caution

Never mount the projector on the ceiling or move it by yourself. Be sure to consult with
qualified Sony personnel (charged).

The lens shift range represents the distance in percent (%) by which the lens can be shifted from
the initial position of the projected image, with full width or full height of the projected image
regarded as 100%.
