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
E]
prevent
X-RADIATION,
shock,
fire
or
other
hazards.
