Introduction
Precautions
Installation
• Prevent internal heat build-up by allowing adequate air circulation.
Do not place the unit on surfaces (rugs, blankets, etc.) or near
materials (curtains, draperies) that may block the ventilation holes.
• Do not install the unit near heat sources such as radiators or air ducts,
nor in a place subject to direct sunlight, excessive dust, mechanical
vibration or shock.
• Do not place the unit near equipment which generates magnetism,
such as a converter or high voltage power lines.
Maintenance
• Clean the cabinet, glass panel and controls with a soft cloth lightly
moistened with a mild detergent solution. Do not use any type of
abrasive pad, scouring powder or solvent, such as alcohol or benzine.
• Do not rub, touch, or tap the surface of the screen with sharp or
abrasive items, like a ball point pen or a screwdriver, as this type of
contact may result in a scratched picture tube.
Transportation
Do not discard the carton and packing materials. When transporting
the unit, use these packing materials so that the unit is properly
packaged.
When carrying the unit, pay attention not to get your hands caught
between the display and the tilt-swivel.

Precautions
Warning on Power Connection
• Use the supplied power cord.
For the customers in U.S.A.
If you do not do this, this display will not conform to mandatory FCC
standards.
For the customers in UK.
If you use the display in UK, please use the supplied UK cable with
UK plug.
for 100 to 120 VAC for 220 to 240 V AC for 240 V AC only
Before disconnecting the power cord, wait at least 30 seconds after
turning off the power switch to discharge static electricity from the
CRT display surface.
After the power has been turned on, the CRT is demagnetized for
approximately 5 seconds. This generates a strong magnetic field
around the bezel which may affect the data stored on magnetic tape or
disks near the bezel. Place such magnetic recording equipment and
tapes/disks at a distance from this unit.
The socket-outlet shall be installed near the equipment and shall be
easily accessible.

Installation
■ step 1: Connect the computer
With the computer switched off, connect the video signal cable to the
display (VGA) connector on your computer. If your computer supports
the DtXI plug-and-play standard, this connection will enable the DDC
communication between the display and the computer.
Also the video signal cable is combined with audio and microphone
cables. If your computer is equipped with sound capability, connect the
audio and microphone plugs to appropriate jacks located on your
computer.
If you use a USB (universal serial bus) device, connect the USB device to
the USB downstream jack and the PC to the USB upstream jack.
10 Getting Started
Note on handling the video signal cable
Do not touch the pins of the video signal cable.
Note on USB ports
USB ports are included to provide state-of-the-art technology. Until USB support is
available at the operating system level, you must supply drivers to use USB devices. You
can upgrade your operating system to a version that supports USB at the operating system
level once a version becomes available.
See the manual that came with your USB device for more information on setting it up and
using it.

14 Using Your Display
45'
Damper wire
Using a white background, very thin horizontal lines on the screen are
visible as shown below. These lines are the damper wires.
The Trinitron tube has a vertically striped Aperture Grille inside. The
Aperture Grille allows more light to pass through to the screen giving
the Trinitron CRT more color and brightness.
The damper wires are attached to the Aperture Grille to prevent
vibration of the Aperture Grille wire so that the screen image is
constantly stable.

Power Saving Function
This display meets the power saving guidelines set by the International
ENERGY Star Program. It is capable of reduced power consumption
when used with a computer equipped with Display Power Management
Signaling (DPMS). By sensing the absence of the sync signal coming
from the computer, it will reduce the power consumption as follows:
•/ CAUTION
The Power Saving function will automatically put the display into Active-off state if the
power switch is turned on without any video signal input. Once the horizontal and vertical
syncs are sensed, the display will automatically return to its Normal operation state.

30 Troubleshooting
Howling (feed-back) is heard
Decrease the volume with +/- buttons, or turn down the
microphone input volume of the sound board.
Picture is scrambled
Check your graphics board manual for the proper display setting on
the display.
Check this manual and confirm that the graphic mode and the
frequency at which you are trying to operate is supported. Even
within the proper range, some video boards may have a sync pulse
that is too narrow for the display to sync correctly.
Color is not uniform
-> Trip the cl) switch once to activate the Auto-degauss cycle’".
Picture is flickering
If the refresh rate is not appropriate, the picture may flicker. Set the
refresh rate of the non-interlace mode as high as possible on the
computer. For details on how to set the refresh rate, consult the dealer
of your computer or video board.
Screen image is not centered or sized properly
Adjust picture centering, size, or geometry (rotation/ pincushion) on
the OSD (pages 19-22).
Some video modes do not fill the screen to the edge of the display.
There is no single answer to solve the problem. There is a tendency for
this problem to occur on higher refresh timings.
Picture is fuzzy
Adjust the contrast and brightness on the OSD (pages 17,18). Some
brands of SVGA boards have an excessive video output level which
creates a fuzzy picture at maximum contrast.
-> The GPE setting may not be proper for the picture. Selecting a lower
GPE number may improve the picture (page 25).
Trip the (1) switch once to activate the Auto-degauss cycle*.
Picture bounces or has wavy oscillations
Isolate and eliminate any potential sources of electric or magnetic
fields. Common causes for this symptom are electric fans, fluorescent
lighting, laser printers, etc.
If you have another display close to this display, increase the distance
between them to reduce interference.
Try plugging the display into a different AC outlet, preferably on a
different circuit.
Picture appears to be ghosting
. Eliminate the use of video extension cables and/or video switch boxes
if this symptom occurs. Excessive cable length or weak connections
can produce this symptom.

Troubleshooting 31
Fine horizontal lines (wires) are visible
These wires stabilize the vertically striped Aperture Grille. The
Aperture Grille allows more light to pass through to the screen giving
the Trinitron CRT more color and brightness.
Wavy or elliptical (moire) pattern is visible
Due to the relationship between resolution, display Aperture Grille
pitch and the pitch of some image patterns, certain screen
backgrounds, especially gray, sometimes show moire which looks like
wavy lines. This can only be eliminated by changing your desktop
pattern.
Hum is heard right after the power is turned on
-> When the power is turned on, the Auto-degauss cycle* is activated.
While the Auto-degauss cycle is activated, a hum may be heard for
about 3 seconds. This is not a malfunction.
• The Auto-degauss function demagnetizes the metal frame of the CRT to obtain
a neutral field for uniform color reproduction. If a second degauss cycle is
needed, allow a minimum interval of 20 minutes for the best result.
• If the problem persists, call your authorized Sony dealer from a
location near you, or call Sony Technical Support at 1-888-4SONYPC
(1-888-476-6972).
• Note the model name and the serial number of your display. Also note
the make and name of your computer and video board.
