1 CAUTION
No modification of any circuit should be attempted.
Service work should only he performed after you are
thorughly familiar with all of the following safety checks
and servicing guide lines.
2 SAFETY.CHECK
Care should be taken while servicing this CRT display
because of the high voltage used in the deflection cir-
cuits.
These
voltages
are
exposed
in
such
areas.
as
the
associated flyback and yoke circuits.
3 FIRE & SHOCK HAZARD
3-1 Insert an isolation transformer between the CRT
display and AC power line before servicing chassis.
3-2 In servicing pay attention to origina! lead dress
“especially in the - high voltage circuit. If a short
circuit is found, replace all parts which have been
overheated as a result of the short circuit.
3-3 All the protective devices must be reinstalled per
original design.
3-4 Soldering must be inspected for possibly cold
' solder joints, frayed leads, damaged insulation,
solder splashes or sharp solder points. Be certain to
remove all foreign material.
4 LEAKAGE CURRENT COLD CHECK
4-1 Unplug the AC cord and connect a jumper between
the two prongs on the plug.
4-2. Turn the CRT display power switch on.
4-3 Measure the resistance value with an ohmmeter
. between .the jumpered AC plug and each exposed
metallic part on the CRT display such as metal
frame screwhead, control shafts, etc. When the ex-
posed metallic part has areturn path to the chassis,
the reading should be 1.8 megohm minimum.
5 LEAKAGE CURRENT HOT CHECK
5-1 Plug the AC cord directly into the AC outlet. Do
_ Not use an isolation transformer during this check.
5-2. Connect a 1500 ohm, 10 watt resistor, paralleled
by a0.15uF capacitor between each exposed me-
tallic part and good earth ground (as shown in
Fig. 1).
5-3 Use an AC voltmeter with 1000 ohm/volt or more
sensitivity and measure the AC voltage across
the combination 1500 ohm resistor and 0.15uF
Capacitor, :
5-4 Move the resistor connection to ‘each exposed
metallic part and measure the voltage.
5-5 Reverse the polarity of the AC plug in the AC
outlet and repeat the above measurement.
5-6 Voltage measured must not exceed 7.5 volt RMS,
from any exposed metallic part to ground.
A leakge current tester may be used in the above
hot check, in which case any current measured
must not exceed 5.0 milliamp. In the case of a
measurement exceeding the 5.0 milliamp value, a
rework is required to eliminate the chance of a
shock hazard.

METALRARTS 15002, 10W GROUND)
Fig. 1
Note: High voltage is present when this CRT display is
operating. Always discharge the anode of the
picture tube to the display chassis to prevent
shock hazard.
6 IMPLOSION PROTECTION
All Panasonic picture tubes are equipped with an integral
implosion protection system, but care should be taken
to avoid damage and scratching during installation.
Use only Panasonic replacement picture tubes.
7 X-RADIATION
WARNING: The only potential source of X-Radiation
is the picture tube. However when the high
voltage circuitry is operating properly there
is no possibility of X-Radiation problem.
The basic precaution which must be exer-
cised is to keep the high voltage at the
following factory-recommended level.
Note: !t is important to use an accurate periodically
calibrated high voltage meter.
7-1 To measure the high voltage, use a high impedance
high voltage meter, connect (—) to the external
conductive coating (aquadag) of CRT and (+) to
the CRT anode button.
7-2. Turn the Brightness control fully counterclock-
wise.
7-3 Measure the high voltage. The high voltage meter
should indicate at the following factory-recom-
mended level.
7-4 |f the upper meter indication exceeds the maxi-
mum level, immediate service is required to
prevent the possibility of premature component
failure.
7-5 To prevent X-Radiation possibility, it is essential
to use the specified picture tube.
7-6 The nominal high voltage is 24kV and must not
exceed 28kV at zero beam current at rated
voltage.
PRLS IMPORTANT Ss AFETY NOTICE Reeseieretsteretreteeristeze anette
There are special components used in this CRT
Display which are important for safety.
These parts are identified by the international symbol
3 A on the schematic diagram and on the replacement
parts list. It is essential that these critial parts should
fi be replaced with manufacture’s specified parts to

Adjust the VR811 (AVR) so as that the voltage at
TP85 (test point of main P.W.A) or TP87 (test point
of CRT P.W.A) shall be 100V.
2. Purity adjustment
If partial color phase irregularity is found on the
screen, make the following adjustment.
(1) Degauss the magnetism of chassis and CRT with
external degaussing coil.
(2) Adjust the purity magnet until each of the red,
green and blué channels is free of color phase
irregularity. ,
® |f partial color phase irregularity cannot be corrected
by the above when the CRT or deflection yoke has
been replaced, make the following adjustment.
(1) Make sure that this adjustment is done later
than 30 minutes after power on.

ADJUSTMENT PROCEDURE
The final confirmation method for purity
In the natural magnetic field, rotate the monitor in
the direction of East, West, South and North. Earth’s
magnetic field may cause magnetism on the monitor.
Confirm that the automatic degaussing circuit built
in the monitor erase the amount of magnetism which
was introduced with above rotation.
The degaussing circuit operates only when ‘the
monitor is cold, you must wait for the monitor to
cool after each purity test.
. Convergence adjustment
1) Input the mixed cross-hatch pattern of R and B with
the signal generator. :
2) Match the R and B at screen center with four pole
magnet. (Rotate the two ring magnets and R.B.
move circularly with the other direction § re-
spectively.)
3) Input the mixed cross-hatch pattern of R.G.B. with
the signal generator.
4) At the screen center, match R and B to G with
the six-pole magnet.
5) Make the fine tuning of D.Y. location so as to get
good convergence on the whole screen.
6) Adjust the convergence of the fringe area (four
corners), using VR451B and VR452B.
au
\f the convergence on the fringe area is bad, put ‘‘the
magnetic small pieces’’ at the four corners of D.Y.
and fix them so the convergence becomes better.
Note: Caution for putting ‘the magnetic small pieces’
(1) Take more than 20mm distance from anode cap.
(2) Don't put them together.
(3) Don’t put it on some other labels.
v)
After the convergence adjustment, confirm if -purity
is OK.
In case purity is no good, back to [2] purity adjust-
ment and re-adjust the purity.

8) Repeat the above procedure in several times to get
the best purity and convergence.

.
Height
adjustment
Adjust
VR402
(Height)
so
the
vertical
size
is
180mm.
. Horizontal Hold (H. Hold) adjustment
1) Turn the horizontal hold control (VR511)
and find the position in the low oscillator fre-
quency direction at which the screen begins to
Move (f_Qw) and the position in the high oscilla-
tor frequency direction at which the screen
begins to move (fyiGH).
2) Set the adjustment to the point physically half-
way between the fLow and frig positions
found in step 1.
. Vertical Hold (V. Hold) adjustment
Turn the vertical hold control (VR401) in the
direction
of
lower
oscillation
frequencies
(clockwise)
until
the
screen
begins
to
roll.
Then,
turn
the
adjust-
ment
back
counter-clockwise
until
the
vertical
synchronization takes hold (the position is about 45
degrees
clockwise
from
center).
. Sub Horizontal Phase Control (Sub H.P.C.) adjustment
Center the image in the middle of the screen with the
sub H.P.C. control (VR502).
. V. Center adjustment
Adjust VR403 (V. Center) to locate the character
area at the CRT center.

3) Turn the brightness contro! (VR501) to MIN,
4) Turn the screen control until it comes to the
point where the back raster and. flyback line
disappear,
5) Connect a digital voltmeter provided with a high
_impedance. probe, between the test point of the
CRT

and
ground
(TP66)
and
measure
—
G2 voltage. Then, turn the screen VR to the
extent of —T0V, thereby reducing G2 voltage.
After this, remove the probe.
6) Turn the brightness contorl (VR501) to MAX,
7) Turn the SUB-BRIGHT control (VR1301) to
adjust the luminance to 100 cd/m? (nit).
8) Turn the R-Drive control (VR621) and B-Drive
contor! (VR623) until the chrominance is
X = 0.281 and Y = 0.311, respectively.
9) Turning the brightness contro! (VR501), set the
luminance to 5 ~ 10cd/m? (nit).
10) Check the chrominance volue and if it comes out
of the specified chrominance range, turn the low
light control R-LOW, G-LOW and B-LOW
until it comes within the specification.
11) Cause the brightness contro! to be varied from
maximum value to the minimum value and
confirm the luminance and the color tracking.
If
anything
is
found
unusual,
repeat
the

to 10).
12) Lock the screen control with lacquer coating.
