Entering New Timings

When using a video mode that is not one of the factory
preset modes, some fine tuning may be required to optimize
the display to your preferences. Simply adjust the monitor
according to the preceding adjustment instructions. The
adjustments will be stored automatically and recalled
whenever that mode is used.
A total of 8 user-defined modes can be stored in memory.
If the 9th mode is entered, it will replace the first.
Power Saving Function
This monitor meets the power saving guidelines set by the
International E NERGY S TAR Program as well as the more
stringent TCO92 803299 (NUTEK) guidelines. 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 monitor 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 monitor will automatically return to
its Normal operation state.

Plug and Play

This monitor complies with DDC TM 1 and DDC2B, which are
the Display Data Channel (DDC) standards of VESA.
When a DDC1 host system is connected, the monitor
synchronizes with the V. CLK in accordance with the VESA
standards and outputs the EDID (Extended Display
Identification Data) to the data line.
When a DDC2B host system is connected, the monitor
automatically switches to the DDC2B communication.
DDC TM is a trademark of the Video Electronics Standard
Association.
Use of the Tilt-Swivel
With the tilt-swivel, this unit can be adjusted to be viewed at
your desired angle within 180˚ horizontally and 20˚ vertically.
To turn the unit vertically and horizontally, hold it at its
bottom with both hands.

Damper Wire

Using a white background, very thin horizontal stripes on
the screen are visible as shown on the illustration. These
stripes are damper wires. These wires are attached to the
aperture grille inside the Trinitron tube and are there to
dampen vibrations of the aperture grille in order to prevent
them from influencing the picture quality.

Troubleshooting

This section may help you isolate a problem and as a result,
eliminate the need to contact technical support, allowing
continued productivity.
No picture
/ If the u POWER indicator is not lit.
— Check that the power cord is properly
connected.
— Check that the u POWER switch is in the
"ON" position.
/ If the u POWER indicator is flashing in green
and orange alternately.
— Check that your computer power switch is in
the "ON" position.
— The monitor will recover when you press any
key on the keyboard of the computer.
— Check that the video cable is properly
connected.
— Ensure that no pins are bent or pushed in the
HD15 connector of the cable.
— Check that the video card is seated
completely in a proper bus slot.
— Check that the video sync signal is within
that specified for the monitor.
— If using a Macintosh system, check that a
proper HD15 - D15 adapter is provided to
work correctly with your Macintosh.
— The monitor has a self-diagnose function.
After disconnecting the video signal cable
from the computer, turn on the u POWER
switch of the monitor. Press and hold the "+"
side of the > button for 2 seconds, then color
bars will appear. The monitor is operating
normally if the red, green, and blue color bars
appear. Contact the maker of the computer to
which the monitor is connected.
/ If the u POWER indicator is flashing.
— There is a potential monitor failure. Contact
your dealer.
If the message of "OUT OF SCAN RANGE" appears on the
screen
/ Check that the video sync signal is specified for
the monitor.
Picture is scrambled
/ Check your graphics board manual for the
proper monitor setting on your Multiscan 100ES/
200ES.
/ 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 monitor to sync
correctly.
Color is not uniform
/ If the monitor is close to any potential sources of
magnetic fields such as a speaker, or you turn the
monitor while the u POWER switch is in the
"ON" position, color may not be uniform. Trip
the u POWER 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 detailes 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 the "CENTER," "SIZE," or "GEOMETRY"
on the OSD (pages 5, 6).
/ Some video modes do not fill the screen to the
edge of the monitor. There is no single answer to
solve the problem. There is a tendency to have
this problem on higher refresh timings and
Macintosh video timings.
Picture is fuzzy
/ Adjust the "CONTRAST" and "BRIGHTNESS"
on the OSD (page 5). We have come across
several brands of SVGA boards that have an
excessive video output level which creates a
fuzzy picture at max contrast.
/ Trip the u POWER 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, and so on.
/ If you have another monitor close to this
monitor, increase the distance between them to
reduce the interference.
/ Try plugging the monitor into a different AC
outlet, preferably on a different circuit.
/ Try the monitor on a completely different
computer in a different room.
Picture appears to be ghosting
/ Eliminate the use of video cable extension cables
and/or video switch boxes if this symptom
occurs. Excessive cable length or weak
connections can produce this symptom.
A fine horizontal line (wire) is visible
/ This wire stabilizes the vertically striped
Aperture Grille (page 8). This 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,
monitor AG pitch and the pitch of some image
patterns, certain screen backgrounds, especially
gray, sometimes show moire. This can only be
eliminated by changing your desktop pattern.
Just after turning the monitor on, a "boon" noise is heard
/ Just after turning the monitor on, a noise may be
heard for about 3 seconds.
This noise is not failure, it is caused by the Auto-
degauss cycle∗.
∗ 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 your monitor.
• Note the model name and the serial number of your monitor.
Also note the make and name of your computer and video
board.
