PRECAUTIONS

1.1 SAFTY PRECAUTIONS

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.
1.1.1 Precautions during Servicing
(1) Locations requiring special caution are denoted by labels
and inscriptions on the cabinet, chassis and certain parts of the product.When performing service, be sure to read and comply with these and other cautionary notices appearing in the operation and service manuals.
(2) Parts identified by the symbol and shaded ( ) parts
are critical for safety. Replace only with specified part numbers.
NOTE :
Parts in this category also include those specified to comply with X-ray emission standards for products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as specified.
(4) Use specified internal wiring. Note especially:
• Wires covered with PVC tubing
• Double insulated wires
• High voltage leads
(5) Use specified insulating materials for hazardous live parts.
Note especially:
• Insulation Tape
• PVC tubing
•Spacers
• Insulation sheets for transistors
•Barrier
(6) When replacing AC primary side components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.
emission. Consequently, when servicing these products, replace the cathode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits.Unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube.
(12) Crimp type wire connectorIn such cases as when replacing
the power transformer in sets where the connections between the power cord and power trans former primary lead wires are performed using crimp type connectors, if replacing the connectors is unavoidable, in order to prevent safety hazards, perform carefully and precisely according to the following steps.
Connector part number :E03830-001
Required tool : Connector crimping tool of the proper type which will not damage insulated parts.
Replacement procedure
a) Remove the old connector by cutting the wires at a
point close to the connector.Important : Do not reuse a connector (discard it).
cut close to connector
Fig.1-1-3
b) 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.
15 mm
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Metal sleeve
Fig.1-1-1
(7) Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors, etc.)
(8) Check that replaced wires do not contact sharp edged or
pointed parts.
(9) When a power cord has been replaced, check that 10-15
kg of force in any direction will not loosen it.
Power cord
Fig.1-1-2 (10) Also check areas surrounding repaired locations. (11) Products using cathode ray tubes (CRTs)In regard to such
products, the cathode ray tubes themselves, the high voltage circuits, and related circuits are specified for compliance with recognized codes pertaining to X-ray

1.1.2 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) Insulation resistance test
Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.).See table 1 below.
(2) Dielectric strength test
Confirm specified dielectric strength or greater between power cord plug prongs and exposed accessible parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). See Fig.1-1-11 below.
(3) Clearance distance
When replacing primary circuit components, confirm specified clearance distance (d), (d') between soldered terminals, and between terminals and surrounding metallic parts. See Fig.1-1-11 below.

(4) Leakage current test
Confirm specified or lower leakage current between 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.). Measuring Method : (Power ON)Insert load Z between earth ground/power cord plug prongs and externally exposed accessible parts. Use an AC voltmeter to measure across both terminals of load Z. See Fig.1-1-9 and following Fig.1-1-12.

(5) Grounding (Class 1 model only)
Confirm specified or lower grounding impedance between earth pin in AC inlet and externally exposed accessible parts (Video in, Video out, Audio in, Audio out or Fixing screw etc.).Measuring Method: Connect milli ohm meter between earth pin in AC inlet and exposed accessible parts. See Fig.1-1-10 and grounding specifications.

DISASSEMBLY

3.1 BEFORE ASSEMBLY AND DISASSEMBLY

3.1.1 Precautions
• Be sure to disconnect the power supply unit prior to mounting and soldering of parts.
• Prior to removing a component part that needs to disconnect its connector(s) and its screw(s), first disconnect the wire(s) from the connector(s), and then remove the screw(s).
• When connecting/disconnecting wires, pay enough attention not to damage the connectors.
• When inserting the flat wire to the connector, pay attention to the direction of the flat wire.
• Be careful in removing the parts to which some spacer or shield is attached for reinforcement or insulation.
• When replacing chip parts (especially IC parts), first remove the solder completely to prevent peeling of the pattern.
• Tighten screws properly during the procedures. Unless otherwise specified, tighten screws at a torque of 0.088N
·cm). However, as this is a required value at the time of
(0.9kgf production, use the value as a measuring stick when proceeding repair services. (See "SERVICE NOTE" as for tightening torque.)

When the HDD is replaced, be sure to refer to REPLACING HDD in "SECTION2 SPECIFIC SERVICE INSTRUCTIONS" for the procedure after HDD replacement.
NOTE3c:
Be careful as the GELS at the four corners are easily come off when the HDD is removed from the main unit. If the GELS come off, be sure to attach them in the correct direc­tion shown in the figure. Attach the GELS with their HOLES on the same side of the connector.
NOTE3d:
When connecting the FPC to the connector, insert the FPC straight into the connector. When locking the connector, be careful not to give so much load that it bends the board.
NOTE3e:
In this procedure, the FPC connected to the HDD connector is not removed. If the FPC is removed due to broken wire, be careful in attachment direction. Be sure to connect the STOPPER side to the HDD. Pay attention as wrong attachment could damage the HDD.
