SAFETY PRECAUTIONS
1. The design of this product contains special hardware, many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the
original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to those
used in the original circuits. Service should be performed by
qualified personnel only.
2. Alterations of the design or circuitry of the products should
not be made. Any design alterations or additions will void
the manufacturer’s warranty and will further relieve the
manufacturer of responsibility for personal injury or property
damage resulting therefrom.
3. Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics
are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by
using replacement components rated for higher voltage,
wattage, etc. Replacement parts which have these special
safety characteristics are identified in the parts list of
Service manual. Electrical components having such
features are identified by shading on the schematics
and by ( ！) on the parts list in Service manual. The use
of a substitute replacement which does not have the same
safety characteristics as the recommended replacement
part shown in the parts list of Service manual may cause
shock, fire, or other hazards
4. Don’t short between the LIVE side ground and
ISOLATED (NEUTRAL) side ground or EARTH side
ground when repairing. Some model’s power circuit is
partly different in the GND. The difference of the GND is
shown by the LIVE: ( ) side GND, ISOLATED (NEUTRAL) :
( ) side GND and EARTH : ( ) side GND. Don’t short
between the LIVE side GND and ISOLATED (NEUTRAL)
side GND or EARTH side GND and never measure with a
measuring apparatus (oscilloscope etc.) the LIVE side GND
and ISOLATED (NEUTRAL) side GND or EARTH side GND
at the same time. If above note will not be kept, a fuse or
any parts will be broken.
5. If any repair has been made to the chassis, it is
recommended that the +B setting should be checked or
adjusted (See ADJUSTMENT OF +B POWER SUPPLY).
6. The high voltage applied to the picture tube must conform
with that specified in Service manual. Excessive high
voltage can cause an increase in X-Ray emission, arcing
and possible component damage, therefore operation under
excessive high voltage conditions should be kept to a
minimum, or should be prevented. If severe arcing occurs,
remove the AC power immediately and determine the cause
by visual inspection (incorrect installation, cracked or melted
high voltage harness, poor soldering, etc.). To maintain the
proper minimum level of soft X-Ray emission, components
in the high voltage circuitry including the picture tube must
be the exact replacements or alternatives approved by the
manufacturer of the complete product.
7. Do not check high voltage by drawing an arc. Use a high
voltage meter or a high voltage probe with a VTVM.
Discharge the picture tube before attempting meter
connection, by connecting a clip lead to the ground frame
and connecting the other end of the lead through a 10kΩ
2W resitor to the anode button.
8. When service is required, observe the original lead dress.
Extra precaution should be given to assure correct lead
dress in the high voltage circuit area. Where a short circuit
has occurred, those components that indicate evidence of
overheating should be replaced. Always use the
9. manufacturer’s replacement components.
10. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control
knobs, metal cabinet, screwheads, earphone jack, control
shafts, etc.) to be sure the product is safe to operate without
danger of electrical shock.
11. The surface of the TV screen is coated with a thin film which
can easily be damaged. Be very careful with it when handle
the TV. Should the TV screen become soiled, wipe it with a
soft dry cloth. Never rub it forcefully. Never use any cleaner
or detergent on it.
(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal
parts exposed to the user, particularly any exposed metal
part having a return path to the chassis should withstand a
voltage of 3000V AC (r.m.s.) for a period of one second.
(…Withstand a voltage of 1100V AC (r.m.s.) to an appliance
rated up to 120V, and 3000V AC (r.m.s.) to an appliance
rated 200V or more, for a periode of one second.)
This method of test requires a test equipment not generally
found in the service trade.
(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use
a line isolation transformer during this check.). Using a
“Leakage Current Tester”, measure the leakage current
from each exposed metal part of the cabinet, particularly
any exposed metal part having a return path to the chassis,
to a known good earth ground (water pipe, etc.). Any
leakage current must not exceed 0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.2mA AC
(r.m.s.).
●Alternate Check Method
Plug the AC line cord directly into the AC outlet ( do not use
a line isolation transformer during this check.). Use an AC
voltmeter having 1000 ohms per volt or more sensitivity in
the following manner. Connect a 1500 Ω10W resistor
paralleled by a 0.15 μF AC-type capacitor between an
exposed metal part and a known good earth ground (water
pipe, etc.). Measure the AC voltage across the resistor with
the AC voltmeter. Move the resistor connection to each
exposed metal part, particularly any exposed metal part
having a return path to the chassis, and measure the AC
voltage across the resistor. Now, reverse the plug in the AC
outlet and repeat each measurement. Any voltage
measured must not exceed 0.75V AC (r.m.s.). This
corresponds to 0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.3V AC
(r.m.s.).
This corresponds to 0.2mA AC (r.m.s.)

Note
1. The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono intercarrier FM demodulator
/QSS IF amplifier and East-West output or not) and on some software control bits. The valid combinations are given in
table 1.
2. the vertical guard function can be controlled via pin 49 or pin 50. the selection is made by means of the
IVG bit in subaddress 2BH.

Note
1. When additional (external) selectivity is required for FM-PLL system pin 32 can be used as sound IF input.
This function is selected by means of SIF bit in subaddress 28H.
2. the reference output signal is only available for the CMB1/CMB0 setting of 0/1. for the other settings this pin is
a switch output(see also 5 table 67).

8. PURITY / CONVERGENCE ADJUSTMENT
PURITY ADJUSTMENT
1. Demagnetize CRT with the demagnetizer.
2. Loosen the retainer screw of the deflection yoke.
3. Remove the wedges.
4. Input a green raster signal from the signal generator,
and turn the screen to green raster.
5. Move the deflection yoke backward.
6. Bring the long lug of the purity magnets on the short
lug and position them horizontally. (Fig2)
7. Adjust the gap between two lugs so that the GREEN
RASTER will come into the center of the screen. (Fig.
3)
8. Move the deflection yoke forward, and fix the position
of the deflection yoke so that the whole screen will
become green.
9. Insert the wedge to the top side of the deflection yoke
so that it will not move.
10. Imput a crosshatch signal.
11. Verify that the screen is horizontal.
12. Input red and blue raster signals, and make sure that
purity is properly adjusted.
