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
customer, always make a safety check of the
entire instrument, including, but not limited to, the
following items:
a. Be sure that no built-in protective devices are
defective 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 operate 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
instrument completely reassembled, plug the
AC line cord directly into a 120 V AC outlet. (Do
not use an isolation transformer during this
test.) Use a leakage 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.

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 Xradiation protection, the replacement picture
tube must be the same type as the original.
CURRENT
TESTER
+
EARTH
GROUND
_
1-3-1TVDVDN_ISP
Page 8
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 servicing 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 Xradiation 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 safetyrelated 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
connected directly to one conductor of the AC
power cord and maybe 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 they comply with
the recognized product safety and electrical codes
1-3-2TVDVDN_ISP
Page 9
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.
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
producing parts (heat sinks, 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 DVD/VCR
connectors, first, disconnect the AC plug from the
AC supply socket.

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)

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

Standard Notes
WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “#” in
the schematic diagram and the parts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.
Notes:
1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.
2. All resistance values are indicated in ohms
(K = 10
3. Resistor wattages are 1/4W or 1/6W unless
otherwise specified.
4. All capacitance values are indicated in µF
(P = 10
5. All voltages are DC voltages unless otherwise
specified.

supply circuit, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly,when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
CAUTION !
Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1601) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

CAUTION ! :
For continued protection against risk of fire,
replace only with same type 4 A, 125V fuse.
ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.
