IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical
codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally
important to implement the following precautions when a set is being serviced.
Safety Precautions for TV Circuit
1. Before returning an instrument to the custom-
er, always make a safety check of the entire instru-
ment, including, but not limited to, the following
items:
a. Be sure that no built-in protective devices are de-
fective and have been defeated during servicing.
(1) Protective shields are provided on this chassis
to protect both the technician and the customer.
Correctly replace all missing protective shields, including any removed for servicing convenience. (2)
When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all
protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not oper-
ate this instrument or permit it to be operated
without all protective devices correctly installed and functioning. Servicers who defeat
safety features or fail to perform safety checks
may be liable for any resulting damage.
b. Be sure that there are no cabinet openings through
which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to, (1) spacing
between the picture tube and the cabinet mask, (2)
excessively wide cabinet ventilation slots, and (3)
an improperly fitted and/or incorrectly secured
cabinet back cover.
c. Antenna Cold Check - With the instrument AC
plug removed from any AC source, connect an
electrical jumper across the two AC plug prongs.
Place the instrument AC switch in the on position.
Connect one lead of an ohmmeter to the AC plug
prongs tied together and touch the other ohmmeter lead in turn to each tuner antenna input exposed terminal screw and, if applicable, to the
coaxial connector. If the measured resistance is
less than 1.0 megohm or greater than 5.2 megohm, an abnormality exists that must be corrected
before the instrument is returned to the customer.
Repeat this test with the instrument AC switch in
the off position.
d. Leakage Current Hot Check - With the instru-
ment completely reassembled, plug the AC line
cord directly into a 120V AC outlet. (Do not use an
isolation transformer during this test.) Use a leak-
age current tester or a metering system that complies with American National Standards Institute
(ANSI) C101.1 Leakage Current for Appliances
and Underwriters Laboratories (UL) 1410, (50.7).
With the instrument AC switch first in the on position and then in the off position, measure from a
known earth ground (metal water pipe, conduit,
etc.) to all exposed metal parts of the instrument
(antennas, handle brackets, metal cabinet, screw
heads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current
measured must not exceed 0.5 milli-ampere. Reverse the instrument power cord plug in the outlet
and repeat the test.

SHOCK HAZARD THAT MUST BE ELIMINATED
BEFORE RETURNING THE INSTRUMENT TO
THE CUSTOMER OR BEFORE CONNECTING
THE ANTENNA OR ACCESSORIES.
e. X-Radiation and High Voltage Limits - Because
the picture tube is the primary potential source of
X-radiation in solid-state TV receivers, it is specially constructed to prohibit X-radiation emissions.
For continued X-radiation protection, the replacement picture tube must be the same type as the
original. Also, because the picture tube shields
and mounting hardware perform an X-radiation
protection function, they must be correctly in place.
High voltage must be measured each time servic-
1-3-1 TD204IMP
ing is performed that involves B+, horizontal deflection or high voltage. Correct operation of the
X-radiation protection circuits also must be reconfirmed each time they are serviced. (X-radiation
protection circuits also may be called "horizontal
disable" or "hold down.") Read and apply the high
voltage limits and, if the chassis is so equipped,
the X-radiation protection circuit specifications given on instrument labels and in the Product Safety
& X-Radiation Warning note on the service data
chassis schematic. High voltage is maintained
within specified limits by close tolerance safety-related components/adjustments in the high-voltage
circuit. If high voltage exceeds specified limits,
check each component specified on the chassis
schematic and take corrective action.
2. Read and comply with all caution and safety-related notes on or inside the receiver cabinet, on the
receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of this TV receiver. Design alterations and additions, including,
but not limited to circuit modifications and the addition of items such as auxiliary audio and/or video
output connections, might alter the safety characteristics of this receiver and create a hazard to the
user. Any design alterations or additions will void
the manufacturer's warranty and may make you,
the servicer, responsible for personal injury or
property damage resulting therefrom.
4. Picture Tube Implosion Protection Warning -
The picture tube in this receiver employs integral
implosion protection. For continued implosion protection, replace the picture tube only with one of
the same type number. Do not remove, install, or
otherwise handle the picture tube in any manner
without first putting on shatterproof goggles
equipped with side shields. People not so
equipped must be kept safely away while picture
tubes are handled. Keep the picture tube away
from your body. Do not handle the picture tube by
its neck. Some "in-line" picture tubes are equipped
with a permanently attached deflection yoke; because of potential hazard, do not try to remove
such "permanently attached" yokes from the picture tube.
5. Hot Chassis Warning -
a. Some TV receiver chassis are electrically connect-
ed directly to one conductor of the AC power cord
and may be safety-serviced without an isolation
transformer only if the AC power plug is inserted
so that the chassis is connected to the ground side
of the AC power source. To confirm that the AC
power plug is inserted correctly, with an AC voltmeter, measure between the chassis and a known
earth ground. If a voltage reading in excess of 1.0V
is obtained, remove and reinsert the AC power
plug in the opposite polarity and again measure
the voltage potential between the chassis and a
known earth ground.
b. Some TV receiver chassis normally have 85V
AC(RMS) between chassis and earth ground regardless of the AC plug polarity. This chassis can
be safety-serviced only with an isolation transformer inserted in the power line between the receiver
and the AC power source, for both personnel and
test equipment protection.
c. Some TV receiver chassis have a secondary
ground system in addition to the main chassis
ground. This secondary ground system is not isolated from the AC power line. The two ground systems are electrically separated by insulation
material that must not be defeated or altered.
6. Observe original lead dress. Take extra care to assure correct lead dress in the following areas: a.
near sharp edges, b. near thermally hot parts-be
sure that leads and components do not touch thermally hot parts, c. the AC supply, d. high voltage,
and e. antenna wiring. Always inspect in all areas
for pinched, out of place, or frayed wiring. Check
AC power cord for damage.
7. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged
should be replaced with components, parts, or wiring that meet original specifications. Additionally,
determine the cause of overheating and/or damage and, if necessary, take corrective action to remove any potential safety hazard.
8. Product Safety Notice - Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual
inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc.. Parts
that have special safety characteristics are identified by a ( # ) on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create shock, fire, and/or
other hazards. The Product's Safety is under review continuously and new instructions are issued
whenever appropriate. Prior to shipment from the
factory, our products are strictly inspected to confirm with the recognized product safety and electrical codes of the countries in which they are to be
sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
1-3-2 TD204IMP
Precautions during Servicing
A. Parts identified by the ( # ) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before soldering.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. When a power cord has been replaced, check that
5~6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. Crimp type wire connector
When replacing the power transformer in sets
where the connections between the power cord
and power transformer primary lead wires are performed using crimp type connectors, in order to
prevent shock hazards, perform carefully and precisely the following steps.
Replacement procedure
1) Remove the old connector by cutting the wires at
a point close to the connector.
Important: Do not re-use a connector (discard it).
2) Strip about 15 mm of the insulation from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. Insert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve at
the center position. Be sure to crimp fully to the
complete closure of the tool.
L. When connecting or disconnecting the TV/DVD
connectors, first, disconnect the AC plug from AC
supply socket.
1-3-3 TD204IMP
Safety Check after Servicing
Examine the area surrounding the repaired location
for damage or deterioration. Observe that screws,
parts and wires have been returned to original positions. Afterwards, perform the following tests and confirm the specified values in order to verify compliance
with safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d') between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

not adhere (iron wire). When heating the pins, use
a fine tip soldering iron or a hot air Desoldering
Machine. (Fig. S-1-4)
With Iron Wire:
a. Using desoldering braid, remove the solder from all
pins of the Flat Pack - IC. When you use solder flux
which is applied to all pins of the Flat Pack - IC, you
can remove it easily. (Fig. S-1-3)
b. Affix the wire to a workbench or solid mounting
point, as shown in Fig. S-1-5.
c. Pull up on the wire as the solder melts so as to lift
the IC leads from the CBA contact pads, while
heating the pins using a fine tip soldering iron or
hot air blower.
Note:
When using a soldering iron, care must be taken
to ensure that the Flat Pack - IC is not being held
by glue, or when it is removed from the CBA, it
may be damaged if force is used.
2. Installation
a. Using desoldering braid, remove the solder from
the foil of each pin of the Flat Pack - IC on the CBA,
so you can install a replacement Flat Pack - IC
more easily.

Instructions for Handling
Semiconductors
Electrostatic breakdown of the semiconductors may
occur due to a potential difference caused by electrostatic charge during unpacking or repair work.
Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly grounded to remove any static electricity that may
be charged on the body.
Ground for Work Bench
Be sure to place a conductive sheet or copper plate
with proper grounding (1MΩ) on the work bench or
other surface, where the semiconductors are to be
placed. Because the static electricity charge on the
clothing will not escape through the body grounding
band, be careful to avoid contacting semiconductors to
clothing.
