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 VIEWSAND IN THE PARTS
LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY. CIRCUIT ADJUSTMENTS THAT ARE
CRITICAL FOR SAFE OPERATION ARE IDENTIFIED IN THIS
MANUAL.FOLLOWTHESEPROCEDURESWHENEVERCRITICAL
COMPONENTS ARE 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. Nearly all battery operated digital multimeters
that have a 2V AC range are suitable. (See Figure A)

1-4. PICTURE TUBE REMOVAL
HOW TO HANDLE AN ANODE-CAP
1. Do not use sharp objects which may cause damage to the surface
of the anode-cap.
2. Do not squeeze the rubber covering too hard to avoid damaging the
anode-cap.Amaterialfitting calledashatter-hookterminal is built into
the rubber.
3. Do not force turn the foot of the rubber cover. This may cause the
shatter-hook terminal to protrude and damage the rubber.
REMOVAL OF THE ANODE-CAP
WARNING: Short circuit the anode of the picture tube and the anode-cap to the metal chassis, CRT shield or carbon painted on the
CRT, after removing the anode.
