CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE COVER
(OR BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL ONLY.

The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclo
sure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.

The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.

1. In addition to safety, other parts and
assemblies are specified for conform ance with
such regulations as those applying to spurious
radiation. These must also be replaced only
with specified replacements.
Examples: RF converters, tuner units, antenna
selection switches, RF cables, noise-blocking
capacitors, noise-blocking filters, etc.

2. Use specified internal Wiring. Note especially:

1) Wires covered with PVC tubing

2) Double insulated wires

3) High voltage leads

3. Use specified insulating materials for hazardous
live parts. Note especially:

1) Insulating Tape

2) PVC tubing

3) Spacers (insulating barriers)

4) Insulating sheets for transistors

5) Plastic screws for fixing micro switches

4. When replacing AC prim ary side components
(transformers, power cords, noise blocking
capacitors, etc.), wrap ends o f wires securely
about the terminals before soldering.

5. Make sure that w ires do not contact heat
generating parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.)

6. Check if replaced wires do not contact sharply
edged or pointed parts.

7. Make sure that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.

Please leave them at an appropriate depot.

W A R N IN G :

Before servicing this TV receiver, read the
SAFETY INSTRUCTION and PRODUCT
SAFETY NOTICE.

S A F E T Y IN S T R U C T IO N

The service should not be attempted by anyone

unfamiliar with the necessary instructions on this

apparatus. The following are the necessary

instructions to be observed before servicing.

1. An isolation transform er should be connected in
the power line between the receiver and the
AC line when a service is performed on the

primary of the converter transform er of the set.

2. Comply with all caution and safety related
provided on the back of the cabinet, inside the

cabinet, on the chassis or picture tube.

3. To avoid a shock hazard, always discharge the
picture tube's anode to the chassis ground
before removing the anode cap.

4. Completely discharge the high potential voltage

of the picture tube before handling. The picture
tube is a vacuum and if broken, the glass will
explode.

1/60

5. When replacing a MAIN PCB in the cabinet,
always be certain that all protective are
installed properly such as control knobs,
adjustment covers or shields, barriers, isolation
resistor networks etc.

6. When servicing is required, observe the original
lead dressing. Extra precaution should be given
to assure correct lead dressing in the high
voltage area.

7. Keep wires away from high voltage or high
tempera ture components.

8. Before returning the set to the customer,
always perform an AC leakage current check
on the exposed m etallic parts of the cabinet,
such as antennas, terminals, screwheads, metal
overlay, control shafts, etc., to be sure the set
is safe to operate without danger of electrical
shock. Plug the AC line cord directly to the
AC outlet (do not use a line isolation
transformer during this check). Use an AC
voltmeter having 5K ohm s volt sensitivity or
more in the following manner.
Connect a 1.5K ohm 10 watt resistor paralleled
by a 0.15pF AC type capacitor, between a
good earth ground (water pipe, conductor etc.,)
and the exposed metallic parts, one at a time.
Measure the AC voltage across the combination
of the 1.5K ohm resistor and 0.15 uF
capacitor. R everse the AC plug at the AC
outlet and repeat the AC voltage measurements
for each exposed m etallic part.
The measured voltage must not exceed 0.3V
RMS.
This corresponds to 0.5mA AC. Any value
exceeding this limit constitutes a potential
shock hazard and must be corrected
immediately.
The resistance m easurement should be done
between accessible exposed metal parts and
power cord plug prongs with the power switch
"ON". The resistance should be more than
6M ohms.

AC V O LTM ETER

P R O D U C T S A F E T Y N O T IC E

Many electrical and mechanical parts in this
apparatus have special safety-related
characteristics.

These characteristics are offer passed
unnoticed by visual spection and the protection
afforded by them cannot necessarily be obtained
by using replacem ent components rates for a
higher voltage, wattage, etc.

The replacement parts which have these
special safety characteristics are identified by A
marks on the schematic diagram and on the parts
list.

Before replacing any of these components,
read the parts list in this manual carefully. The
use of substitute replacem ent parts which do not
have the same safety characteristics as specified
in the parts list may create shock, fire, or other
hazards.

9. Must be sure that the ground wire of the AC
inlet is connected with the ground of the
apparatus properly.

Good earth ground

such as the w ater

- pipe, cond u cto r,

etc.

by time on a same still screen and rapidly go down in 5 minutes. When
measuring the color tracking and luminance of a same still screen, be sure
to accomplish the measurement in one minute to ensure its accuracy.

1.11.2 Due to the structure of PDP, the extra-high-bright same screen should not
hold over 5 minutes for fear of branding on the panel.
