IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special safety-related characteristic s 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 s afety characteristics are identifi ed b y 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 electr ical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is e qual ly imp or ­tant 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 spur ious radi ation. Thes e must also be replaced only with specified replacements. Examples: RF conver ters, 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 no t co ntac t he at prod uc -
ing parts (heatsink s, oxide metal film resist ors, fus­ible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has b een replac ed, 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 insu lation 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 complet e clo­sure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconne ct the AC plug from the AC outlet.
1-3-1 DVD_SFNP
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 Distan ce
When replacing primary circuit components, confirm specified clearance dista nce (d) and (d’) between sol ­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)

2. Leakage Curre nt 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 t he ter minals of l oad Z. See Fig. 2 and the following table.

Instructions for Handling Semi-conductors
Electrostatic breakdown of the semi-conductors may occur due to a potenti al difference caused by electro ­static charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a groundi ng ban d (1M ) that is prop­erly grounded to remove any static electr icity that may be charged on the body.
2. Ground for Workbench
(1)Be sure to place a conductive sheet or copper plate
with proper grounding ( 1M) on the wor kbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escap e through the body ground­ing band, be care ful to avoid contacting semi-con ­ductors with your clothing.
