TIMING SPECIFICATION
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 Deep Sleep mode 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 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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK
¡ ON THE SCHEMATIC DIAGRAMS, EXPLODED

PECTED.
AVERTISSEMENT!!
NE JAMAIS METTRE SOUS TENSION QUAND LA
BOBINE DE DEMAGNETISATION EST ENLEVÉE.
ATTENTION AUX COMPOSANTS RELATIFS À LA
SÉCURITÉ!!
LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET
UNE MARQUE
¡ SONT CRITIQUES POUR LA SÉCURITÉ.
NE LES REMPLACER QUE PAR UNE PIÈCE PORTANT LE

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.

Introduction
Congratulations on your purchase of a Sony Multimedia CPD-101VS
display!
This display incorporates over 25 years of Sony experience with Trinitron
display technology, ensuring excellent performance and outstanding
reliability.
This display's wide scan range (30 ­ 70 kHz), together with Digital
Multiscan Technology, allows it to sync to any video mode from
standard VGA through VESA 1024
× 768 at 85 Hz (VESA 1280 × 1024 at
60 Hz).
In addition, its four factory-preset color modes give you unprecedented
flexibility in matching on-screen colors to hard copy printouts.
Furthermore, it features:
· Graphic Picture Enhancement function
improves monitor performance to match the application that you are
running.
With the GPE AUTO MODE, you can use "IntelliLight" compatible
software which will maximize the color and brightness of a window
running a multimedia presentation without affecting the brightness
and contrast of text based applications.
· Integrated stereo speakers with Bass Boost
enables you to enjoy excellent sound reproduction via 3.0 W stereo
speakers.
All together, CPD-101VS delivers incredible performance with the
quality and support you can expect from Sony.
Plug and play
This display complies with DDCTM1 and DDC2B which are the Display
Data Channel (DDC) standards of VESA.
When a DDC1 host system is connected, the display 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 display automatically
switches to DDC2B communication.
DDCTM is a trademark of Video Electronics Standard Association.
Introduction

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, be careful not to get your hands caught
between the display and the tilt-swivel.

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 the UK, please use the supplied UK cable
with the UK plug.
for 100 to 120 V AC
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.
