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 evi-

dent 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 iden-

tified by a # on schematics and in parts lists. Use of a

substitute replacement that does not have the same

safety characteristics as the recommended replace-

ment part might create shock, fire, and/or other haz-

ards. The Product’s Safety is under review

continuously and new instructions are issued when-

ever 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 impor-

tant 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 block-

ing 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 solder-

ing.

F. Observe that the wires do not contact heat produc-

ing parts (heatsinks, oxide metal film resistors, fus-

ible 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 clo-

sure of the tool.

L. When connecting or disconnecting the internal

connectors, first, disconnect the AC plug from the

AC outlet.

1-3

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 posi-

tions. 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 sol-

dered terminals, and between terminals and surround-

ing metallic parts. (See Fig. 1)

Table 1 : Ratings for selected area

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 termi-

nals, 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.

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

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.

1-3-3 How to Remove / Install Flat

Pack-IC

1. Removal

With Hot-Air Flat Pack-IC Desoldering Machine:.

(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)

(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. 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)

2. 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)

(2) Lift each lead of the flat pack-IC upward one by

one, using a sharp pin or wire to which solder will

not adhere (iron wire). When heating the pins, use

a fine tip soldering iron or a hot air desoldering

machine. (Fig. S-1-4)

(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)

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

zers. (Fig. S-1-6)

With Iron Wire:

(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)

(2) Affix the wire to a workbench or solid mounting

point, as shown in Fig. S-1-5.

(3) While heating the pins using a fine tip soldering

iron or hot air blower, pull up the wire as the solder

melts so as to lift the IC leads from the CBA contact

pads as shown in Fig. S-1-5

(4) 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)

(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.

1-3-4 Instructions for Handling

Semi-conductors

Electrostatic breakdown of the semi-conductors may

occur due to a potential difference caused by electro-

static charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a grounding band (1MΩ) that is prop-

erly 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 ground-

ing band, be careful to avoid contacting semi-con-

ductors with your clothing.

Example :

Pin 1 of the Flat Pack-IC

is indicated by a " " mark.
