not a malfunction. However, if there are any
abnormal noises, consult qualified Sony

On light source maintenance
This unit uses a laser, therefore special
caution and facilities are necessary for the
inspection and maintenance of light source
components. Be sure to consult qualified
Sony personnel.
On cleaning
• Be sure to turn the unit off and unplug it
from the wall outlet before cleaning.
• If the unit is rubbed hard with a dirty
cloth, the unit may be scratched.
• If volatile liquids such as insecticide are
sprinkled on the unit, or an item made of
rubber or vinyl stays in physical contact
with the unit for a long time, the unit may
be affected or the surface color may fade.
• Do not touch the projection window with
bare hands.
• To clean the surface of the projection
window:
Gently wipe it with a soft cloth such as an
eyeglass cleaning cloth. If there are
stubborn stains, wipe them up with a
cloth moistened with water. Never use
alcohol, benzene, thinner, acidic cleaning
agents, alkaline cleaning agents, abrasive
cleaning agents, chemical dust cloths,
and so on.

Gently wipe it with a soft cloth. If there
are stubborn stains, wipe up the stains
with a soft cloth which has been soaked
in diluted neutral detergent and
thoroughly wrung out, then wipe the
exterior again with a dry cloth. Do not use
alcohol, benzene, thinner, and so on.
On projector
• Although this unit is manufactured using
very high precision technology, there may
be some permanent black or white pixels
on the projected screen. Also, there may
be striped unevenness in color or
brightness. This is a result of the projector
structure and is not a malfunction. The
color balance of each projector unit
varies; therefore, when multiple LCD
projectors are used, the color
reproduction among projectors may vary,
even if they are of the same model.
• Depending on viewed content, primary
colors such as red, blue, or green are
visible when you move your eyes or under
certain conditions; this is not a
malfunction. It is caused by a "color
breakup" phenomenon which is specific
to the field-sequential color system
adopted into the unit for displaying
images. This phenomenon can be
subdued by diminishing the contrast
between the image and the backdrop,
such as decreasing the brightness of the
unit or increasing the brightness of the
room.
