Power Saving Function
This monitor meets the power-saving guidelines set by
VESA and
E NERGY S TAR, as well as the more stringent
NUTEK .
If the monitor is connected to a computer or video graphics
board that is VESA DPMS (Display Power Management
Signaling) compliant, the monitor will automatically reduce
power consumption in three stages as shown below.
You can set the delay time before the monitor enters the
power saving mode using the OSD. Set the time according
to “Setting the Power Saving Delay Time” on page 1-6.
* Power consumption of the monitor only. The figures in
parentheses are power consumption of the monitor including
the AC adapter.
** “Sleep” and “deep sleep” are power saving modes defined by
the Environmental Protection Agency.

After the time set in “Changing the Power Saving Delay Time”
(page 1-6) has elapsed, the monitor enters the power saving
mode.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part hav-
ing a return to chassis, must not exceed 0.5 mA (500
microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instruments.
2. A battery-operated AC milliammeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOMs that are suitable. Nearly all
battery operated digital multimeters that have a 2 V AC
range are suitable. (See Fig. A)
WARNING!!
NEVER TURN ON THE POWER IN A CONDITION IN
WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

After correcting the original service problem, perform the fol-
lowing safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.

Getting Started
Precautions
Installation
• Prevent internal heat build-up by allowing adequate air
circulation. Do not place the monitor on surfaces (rugs,
blankets, etc.) or near materials (curtains, draperies) that
may block the ventilation holes.
• Do not install the monitor near heat sources such as
radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or shock.
• Do not place the monitor near equipment which generates
magnetism, such as a transformer or high voltage power
lines.
Handling the LCD screen
• Bright points of light (red, blue or green) may appear
on the LCD screen. This is not a malfunction. The LCD
screen is made with high-precision technology and
more than 99.99 % of the picture element is intact.
However, some of the picture element may not
appear or some of the picture element may appear
constantly.
• Do not leave the LCD screen facing the sun as it can
damage the LCD screen. Take care when you place the
monitor by a window.
• Do not push or scratch the LCD screen. Do not place a
heavy object on the LCD screen. This may cause the
screen to lose uniformity.
• If the monitor is used in a cold place, a residual image
may appear on the screen. This is not a malfunction.
When the monitor becomes warm, the screen returns to
normal.
• If a still picture is displayed for a long time, a residual
image may appear. The residual image will eventually
disappear.
• The screen and the cabinet become warm during
operation. This is not a malfunction.
About the fluorescent tube
A specially designed fluorescent tube is installed as the
lighting apparatus for this monitor. If the LCD screen
becomes dark, unstable or does not turn on, consult your
Sony dealer.
Getting Started
for 100 to 120 V AC for 200 to 240 V AC for 240 V AC only
Maintenance
• Clean the cabinet, panel and controls with a soft cloth

Additional Information
Preset and User Modes
This monitor has factory preset modes for the most popular
industry standards for true “plug and play” compatibility.
(See Appendix for a list of the factory preset modes.)
When a new input signal is entered, the monitor selects the
appropriate factory preset mode and momentarily adjusts
the phase calibration to provide a high quality picture to the
center of the screen. The calibration is stored in memory
and is immediately recalled whenever the same input signal
is received.
For input signals that do not match one of the factory preset
modes, the digital Multiscan technology of this monitor
performs all of the adjustments necessary to ensure that a
clear picture appears on the screen for any timing in the
monitor’s frequency range. However, it may be necessary
to fine tune the vertical/horizontal centering. Simply press
the AUTO button or adjust the monitor according to the
adjustment instructions. The adjustments are stored
automatically as a user mode and recalled whenever the
corresponding input signal is received.
Power Saving Function
This monitor meets the power-saving guidelines set by
VESA and
E NERGY S TAR, as well as the more stringent
NUTEK .
If the monitor is connected to a computer or video graphics
board that is VESA DPMS (Display Power Management
Signaling) compliant, the monitor will automatically reduce
power consumption in three stages as shown below.
You can set the delay time before the monitor enters the
power saving mode using the OSD. Set the time according
to “Setting the Power Saving Delay Time” on page 15.
* Power consumption of the monitor only. The figures in
parentheses are power consumption of the monitor including
the AC adapter.
** “Sleep” and “deep sleep” are power saving modes defined by
the Environmental Protection Agency.
*** When your computer enters the power saving mode, the input
signal is cut and NO INPUT SIGNAL appears on the screen.
After the time set in “Changing the Power Saving Delay Time”
(page 15) has elapsed, the monitor enters the power saving
mode.
Troubleshooting
This section may help you isolate the cause of a problem
and as a result, eliminate the need to contact technical
support.
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen. To solve the
