Welcome!
Thank you for purchasing the Sony Color Rear Video
Projection TV. Here are some of the features you will
enjoy with your projection TV:
· On-screen menus that let you set the picture quality,
sound, and other settings.
· Two tuner Picture-in-Picture (PIP) that allows you
to watch another TV channel, video or cable image
as a window picture.
· Surround system that simulates the sound quality of
a concert hall or movie theater.
· SAVA SPEAKER option of the AUDIO menu that
lets you take advantage of the Sony SAVA series
speaker system's surround sound and super woofer
mode when you connect it to the projection TV.
About this manual
The instructions in this manual are for models KP-
41T65, KP-46C65, KP-48S65, KP-53S65, and KP-61S65.
Before you start reading this manual, please check your
model number, located at the rear of the projection TV.
Model KP-53S65 is used for illustration purposes in this
manual. Any differences in operation are clearly
indicated in the text, for example "KP-61T65 only."
The differences in specifications are indicated in the
text.
Instructions in this manual are based on use of the
remote control. You can also use the controls on the
projection TV if they have the same name as those on
the remote control.
Precautions
This projection TV operates on extremely high voltage.
To prevent fire or electric shock, please follow the
precautions below.
Safety
· Operate the projection TV only on 120 V AC.
· One blade of the plug is wider than the other for safety
purposes and will fit into the power outlet only one
way. If you are unable to insert the plug fully into the
outlet, contact your dealer.
· Should any liquid or solid object fall into the cabinet,
unplug the projection TV and have it checked by
qualified personnel before operating it further.
· Unplug the projection TV from the wall outlet if you
are not going to use it for several days or more. To
disconnect the cord, pull it out by the plug. Never
pull the cord itself.
For details concerning safety precautions, see the supplied
leaflet "IMPORTANT SAFEGUARDS."
Note on cleaning
Clean the cabinet of the projection TV with a dry soft
cloth. To remove dust from the screen, wipe it gently
with a soft cloth using vertical strokes only. Stubborn
stains may be removed with a cloth slightly dampened
with solution of mild soap and warm water. Never use
strong solvents such as thinner or benzine for cleaning.
If the picture becomes dark after using the projection TV
for a long period of time, it may be necessary to clean the
inside of the projection TV. Consult qualified service
personnel.
Installing
· To prevent internal heat build-up, do not block the
ventilation openings.
· Do not install the projection TV in a hot or humid
place, or in a place subject to excessive dust or
mechanical vibration.
· Avoid operating the projection TV at temperatures
below 5
°C (41°F).
· If the projection TV is transported directly from a cold
to a warm location, or if the room temperature has
changed suddenly, the picture may be blurred or show
poor color. This is because moisture has condensed on
the mirror or lenses inside. If this happens, let the
moisture evaporate before using the projection TV.
· To obtain the best picture, do not expose the screen to
direct illumination or direct sunlight. It is
recommended to use spot lighting directed down from
the ceiling or to cover the windows that face the screen
with opaque drapery. It is desirable to install the
projection TV in a room where the floor and walls are
not of reflecting material. If necessary, cover them
with dark carpeting or wall paper.

Connecting an antenna/cable TV
system without a VCR
To cable or antenna
Although you can use either an indoor or outdoor
antenna with your projection TV, we recommend that
you connect an outdoor antenna or a cable TV system
to get better picture quality.
Connecting an antenna
Connect your antenna cable to the VHF/UHF antenna
terminal. If you cannot connect your antenna cable
directly to the terminal, follow one of the instructions
below depending on your cable type.
To cable box and cable
Pay cable TV systems use scrambled or encoded signals
requiring a cable box* in addition to the normal cable
connection.
* The cable box will be supplied by the cable company.
Note
· You cannot watch the signal through an AUX connector as a
window picture.

Note
· Do not connect anything to the TO CONVERTER connector in
this case.
