If you have VESA's DPMS compliance display card or software installed in your PC, the monitor can automatically reduce
its power consumption when not in use. If input from keyboard, mouse, or other input devices is detected, the monitor
will automatically "wake up." The following table shows the power consumption and signaling of this automatic power
saving feature.
When a failure occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the
problem. If there is more than one error, the lamp will identify the first of the problem areas.

SAFETY CHECK-OUT
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part
having a return to chassis, must not exceed 0.5 mA (500
microampere). Leakage current can be measured by any one
of three methods.
WARNING!!
NEVER TURN ON THE POWER IN A CONDITION IN WHICH THE
DEGAUSS COIL HAS BEEN REMOVED.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK
ON THE
SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE PARTS
LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONYPARTS WHOSE PART NUMBERSAPPEAR
AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY
SONY. CIRCUIT ADJUSTMENTS THAT ARE CRITICAL FOR SAFE
OPERATION ARE IDENTIFIED IN THIS MANUAL. FOLLOW THESE
PROCEDURES WHENEVER CRITICALCOMPONENTSARE REPLACED
OR IMPROPER OPERATION IS SUSPECTED.
After correcting the original service problem, perform
the following safety checks before releasing the set to
the customer:
1. Check the area of your repair for unsoldered or poorly-
soldered 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
transistors, 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 follows.
1. A commercial leakage tester, such as the Simpson 229
or RCA WT-540A. Follow the manufacturers' instructions
to use these instructions.
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"
indication is 0.75 V, so analog meters must have an
accurate low voltage scale. The Simpson's 250 and
Sanwa SH-63TRD are examples of passive VOMs that
are suitable. N early all battery operated digital
multimeters that have a 2V AC range are suitable. (See
Figure A)

ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
LES COMPOSANTS IDENTIFIES PAR UNE TRAME ET PAR UNE
MARQUE
SUR LES SCHEMAS DE PRINCIPE, LES VUES
EXPLOSEES ET LES LISTES DE PIECES SONT D'UNE IMPORTANCE
CRITIQUE POUR LA SECURITE DU FONCTIONNEMENT. NE LES
REMPLACER QUE PAR DES COMPOSANTS SONY DONT LE
NUMERO DE PIECE EST INDIQUE DANS LE PRESENT MANUEL OU
DANS DES SUPPLEMENTS PUBLIES PAR SONY. LES REGLAGES
DE CIRCUIT DONT L'IMPORTANCE EST CRITIQUE POUR LA
SECURITE DU FONCTIONNEMENT SONT IDENTIFIES DANS LE
PRESENT MANUEL. SUIVRE CES PROCEDURES LORS DE CHAQUE
REMPLACEMENT DE COMPOSANTS CRITIQUES, OU LORSQU'UN
MAUVAIS FONTIONNEMENT SUSPECTE.

Precautions
Installation
Do not install the monitor in the following places:
· on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies) that may block the ventilation holes
· near heat sources such as radiators or air ducts, or in a place
subject to direct sunlight
· in a place subject to severe temperature changes
· in a place subject to mechanical vibration or shock
· on an unstable surface
· near equipment which generates magnetism, such as a
transformer or high voltage power lines
· near or on an electrically charged metal surface
Maintenance
· Clean the screen with a soft cloth. If you use a glass cleaning
liquid, do not use any type of cleaner containing an anti-static
solution or similar additive as this may scratch the screen's
coating.
· Do not rub, touch, or tap the surface of the screen with sharp or
abrasive items such as a ball point pen or screwdriver. This type
of contact may result in a scratched picture tube.
· Clean the cabinet, 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
benzene.
Transportation
When you transport this monitor for repair or shipment, use the
original carton and packing materials.
Warning on Power Connection
· Use the supplied power cord. If you use a different power cord,
be sure that it is compatible with your local power supply.
For the customers in the US
If you do not use the appropriate cord, this monitor will not
conform to mandatory FCC Standards.
· Before disconnecting the power cord, wait at least 30 seconds
after turning off the power to allow the static electricity on the
screen's surface to discharge.
· After the power is turned on, the screen is demagnetized
(degaussed) for about 3 seconds. This generates a strong
magnetic field around the screen, which may affect data stored on
magnetic tapes and disks placed near the monitor. Be sure to keep
magnetic recording equipment, tapes and disks away from the
monitor.
The equipment should be installed near an easily accessible
outlet.

Setup
Connect the monitor to your computer system.
This monitor will sync to platforms running at horizontal
frequencies between 30 and 107 kHz.
Step 1 Make sure the computer system is switched off and attach
the video signal cable to the video output of the computer.
Step 2 Make sure the computer is switched off and attach the
power cord to the monitor. Then, attach the other end of
the power cord to a power outlet.
Step 3 Switch on the monitor and computer.
Step 4 Adjust the user controls according to your personal
preference.
