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 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT540A. 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” indication 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)
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
described right.

POWER SAVING FUNCTION
This monitor meets the power-saving guidelines set by VESA,
E
NERGY STAR, and NUTEK. If the monitor is connected to a
computer or video graphics board that is DPMS (Display Power
Management Signaling) compliant, the monitor will automatically
reduce power consumption in three stages as shown below
.
* Figures reflect power consumption when no USB compatible
peripherals are connected to the monitor.
** “Sleep” and “deep sleep” are power saving modes defined by the
Environmental Protection Agency.
*** When your computer enters power saving mode, the input signal is
cut and NO INPUT SIGNAL appears on the screen before the
monitor enters active off mode. After a few seconds, the monitor
enters power saving mode.

DIAGNOSIS
This monitor is equipped with a self-diagnosis function. If there is
a problem with your monitor or computer(s), the screen will go
blank and the ! (power) indicator will either light up green or
flash orange. If the ! (power) indicator is lit in orange, the
computer is in power saving mode. Try pressing any key on the
keyboard or moving the mouse.
x If the ! (power) indicator is green
1
Disconnect any plugs from the video input 1 and 2
connectors, or turn off the connected computer(s).
2
Press the ! (power) button twice to turn the monitor
off and then on.
3
Move the joystick to the right for 2 seconds before
the monitor enters power saving mode.
If all four color bars appear (white, red, green, blue), the monitor
is working properly. Reconnect the video input cables and check
the condition of your computer(s).
If the color bars do not appear, there is a potential monitor failure.
Inform your authorized Sony dealer of the monitor’s condition.
x If the ! (power) indicator is flashing orange
Press the ! (power) button twice to turn the monitor off
and then on.
If the ! (power) indicator lights up green, the monitor is working
properly.
If the ! (power) indicator is still flashing, there is a potential
monitor failure. Count the number of seconds between orange
flashes of the ! (power) indicator and inform your authorized
Sony dealer of the monitor’s condition. Be sure to note the model
name and serial number of your monitor. Also note the make and
model of your computer and graphic board.

anode-cap can be removed by turning up
the rubber cap and pulling up it in the
direction of the arrow c.
•HOW TO HANDLE AN ANODE-CAP
1 Don’t scratch the surface of anode-caps with sharp shaped
material!
2 Don’t press the rubber hardly not to damage inside of anode-
caps!
A material fitting called as shatter-hook terminal is built in the
rubber.
3 Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or damage the rubber.

ADJUSTMENTS
Note: Hand degauss must be used on stand-by or power-off condition.
This model has an automatic earth magnetism correction function by using an earth magnetism sensor and a LCC coil. When
using a hand degauss while monitor (LCC coil) is being operated, it sometimes gets magnetized, and the system may not
work properly as a result.
•Landing Rough Adjustment
1. Enter the full white signal. (or the full black dots signal).
2. Adjust the contrast to the maximum.
3. Make the screen monogreen.
Note:Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so that
a green raster positions in the center of screen.
5. Adjust the tilt of DY, and fix lightly with a clamp.
Note:“TILT” = “128”.
•Landing Fine Adjustment
1. Put the set inside the Helmholtz coil. (“LCC SW” = “12”)
2. Input the single green signal and set the “CONTRAST” =
“255”.
Note:After the W/B adjustment with 9300K, measure an average
of ΣIk when a full white signal is entered in the CONT
MAX/BRT CENT status. Then make adjustment so that the
specified screen can be attained after aging for 2 hours with
Ik equivalent to 30% of the average value.
3. Demagnetize the metal part of the chassis with the hand degausser and coil
degausser, and the CRT surface with the hand degausser.
Input AC 230V to AC IN, turn on and off the power to perform auto
degaussing. (Perform auto degaussing by setting “FUNCTION SW” = 1.
Return to the original value after use.)
Demagnetize the CRT surface with the hand degausser again.
Note:
(1) Hand degauss must be used on stand-by or power-off condition.
This model has an automatic earth magnetism correction function by using
an earth magnetism sensor and a LCC coil. When using a hand degauss while
monitor (LCC coil) is being operated, it sometimes gets magnetized, and the
system may not work properly as a result.
(2) Adjust in a non-magnetic field.
(3) If adjusting in a magnetic fields, add the shift from the non-magnetic field in
your estimation.
4. Attach the wobbling coil to the designated part of the CRT neck.
5. Attach the sensor of the landing adjustment unit on the CRT surface.

7. Tighten DY screw.
Note:Torque 22 ± 2 kg.cm (2.2 ± 0.2 Nm) auto degauss it.
8. For the up/down swing, swing the DY and insert a wedge so
that the up and down pins are equal at the top and bottom.
Adjust the H.TRP VR of DY so that the horizontal trapezoid is
equal at the left and right. Insert the wedge firmly so that the DY
does not shake.
9. Check the landing of each corner, and if it does not satisfy the
specification, adjust the landing of four corners using “LCC
LT“, “LCC LB”, “LCC RT” and “LCC RB”.
However, the register adjustment must be limited within the
following range.
“LCC NS” 128 ± 15
<Specifications>
Adjust so that the green is within the
specification given right.
4 corner adjust target : within ± 1
The red and blue must be within the
specification given right with respect to
the green.
A difference between red and blue must
be within the specification given right.
“LCC LT”, “LCC LB”, “LCC RT”, “LCC RB”
128 ± 45
After adjustment, save the service data.
10. Remove the sensor and wobbling coil.
11. Switch the signal to R.G.B., and check that each color is pure.
12. Check that the DY is not tilting, and fix the purity Mg with a white pen. Fix
wedges with RTV.
