1-2 IMPORTANT SAFETY PRECAUTIONS

1-2-1 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 carefully 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.

1-2-2 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

edges 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

The power transformer uses crimp type connectors
which connect the power cord and the primary side
of the transformer. When replacing the transformer,
follow these steps carefully and precisely to prevent
shock hazards.
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 a crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to the complete clo­sure of the tool.

L. When connecting or disconnecting the internal

connectors, first, disconnect the AC plug from the
AC outlet.

1-2

1-2-3 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 their original posi­tions. Afterwards, do the following tests and confirm
the specified values 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)

Table 1 : Ratings for selected area

AC Line Voltage Clearance Distance (d) (d’)

Chassis or Secondary Conductor

Primary Circuit Terminals

dd'

120 V

Note: This table is unofficial and for reference only.

Be sure to confirm the precise values.

2. Leakage Current Test

Confirm the specified (or lower) leakage current
between B (earth ground, power cord plug prongs)
and externally exposed accessible parts (RF termi­nals, antenna terminals, video and audio input and
output terminals, microphone jacks, earphone jacks,
etc.) is lower than or equal to the specified value in the
table below.

Measuring Method (Power ON) :

Insert load Z between B (earth ground, power cord
plug prongs) and exposed accessible parts. Use an
AC voltmeter to measure across the terminals of load
Z. See Fig. 2 and the following table.

(1) Prepare the hot-air flat pack-IC desoldering

machine, then apply hot air to the Flat Pack-IC
(about 5 to 6 seconds). (Fig. S-1-1)

Pin 1

1-3-2 Instructions for Connectors

1. When you connect or disconnect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect
the AC cord.

2. FFC (Flexible Foil Connector) cable should be
inserted parallel into the connector, not at an angle.

(2) Remove the flat pack-IC with tweezers while apply-

ing the hot air.

(3) Bottom of the flat pack-IC is fixed with glue to the

CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)

(1) Release the flat pack-IC from the CBA using twee-

zers. (Fig. S-1-6)

Caution:

1. The Flat Pack-IC shape may differ by models. Use
an appropriate hot-air flat pack-IC desoldering
machine, whose shape matches that of the Flat
Pack-IC.

2. Do not supply hot air to the chip parts around the
flat pack-IC for over 6 seconds because damage to
the chip parts may occur. Put masking tape around
the flat pack-IC to protect other parts from damage.
(Fig. S-1-2)

3. The flat pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each
pin or the solder lands under the IC when removing
it.

With Soldering Iron:

(1) 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)

CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)

(5) Release the flat pack-IC from the CBA using twee-

zers. (Fig. S-1-6)

Note:

When using a soldering iron, care must be taken
to ensure that the flat pack-IC is not being held by
glue. When the flat pack-IC is removed from the
CBA, handle it gently because it may be damaged
if force is applied.

2. Installation

(1) 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.

(2) The “I” mark on the flat pack-IC indicates pin 1.

(See Fig. S-1-7.) Be sure this mark matches the 1
on the PCB when positioning for installation. Then
presolder the four corners of the flat pack-IC. (See
Fig. S-1-8.)

(3) Solder all pins of the flat pack-IC. Be sure that none

of the pins have solder bridges.

1-3-5 Instructions for Handling

Semi-conductors

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 (1MΩ) that is prop­erly grounded to remove any static electricity that may
be charged on the body.

2. Ground for Workbench

(4) Be sure to place a conductive sheet or copper plate

with proper grounding (1MΩ) 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.
