Prior to shipment from the factory, JVC products are strictly inspected to conform 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.
•Precautions during Servicing |
|
||
1. Locations requiring special caution are denoted by labels and in- |
12. Crimp type wire connector |
||
scriptions on the cabinet, chassis and certain parts of the product. |
In such cases as when replacing the power transformer in sets |
||
When performing service, be sure to read and comply with these |
where the connections between the power cord and power trans- |
||
and other cautionary notices appearing in the operation and serv- |
former primary lead wires are performed using crimp type connec- |
||
ice manuals. |
|
|
tors, if replacing the connectors is unavoidable, in order to prevent |
|
|
|
safety hazards, perform carefully and precisely according to the |
2. Parts identified by the ! symbol and shaded ( |
|
|
|
|

(1) Remove the old connector by cutting the wires at a point |
||
emission. |
|
|
close to the connector. |
|
|
|
Important : Do not reuse a connector (discard it). |
3.Fuse replacement caution notice.

|
|
|
|
|
|
2) Double insulated wires |
|
|

||
|
3) High voltage leads |
|
|
|
Fig.3 |
|
|
|
|
|
|
|
|
5. |
Use specified insulating materials for hazardous live parts. Note |
(2) Strip about 15 mm of the insulation from the ends of the |
||||
|
especially: |
|
|
|||
|
1) Insulation Tape |
3) Spacers |
5) Barrier |
wires. If the wires are stranded, twist the strands to avoid |
||
|
2) PVC tubing |
4) Insulation sheets for transistors |
frayed conductors. |
|
|
|
6. |
When replacing AC primary side components (transformers, power |
|
15 mm |
|
||
|
|
|
||||
|
cords, noise blocking capacitors, etc.) wrap ends of wires securely |
|
|
|
||
|
about the terminals before soldering. |
|
|
|
|
|
|
|
|
|
|

(3) Align the lengths of the wires to be connected. Insert the |
||
|
|
|
|
wires fully into the connector. |
|

SECTION 1
1.1.1 Precautions
1.Be sure to remove the power supply unit prior to mounting and soldering of parts.
2.When removing a component part that needs to disconnect the connector and to remove the screw for removing itself, first disconnect the connecting wire from the connector and then remove the screw beforehand.
3.When connecting and disconnecting the connectors, be careful not to damage the wire.
4.Carefully remove and handle the part to which some spacer or shield is attached for reinforcement or insulation.
5.When replacing chip parts (especially IC parts), desolder completely first (to prevent peeling of the pattern).
