SECTION 1
PRECAUTIONS
1.1 SAFTY PRECAUTIONS
Prior to shipment from the factory, JVC products are strictly in-
spected to conform with the recognized product safety and elec-
trical 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 com-
pliance 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.
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.
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 volt-
age circuits, and related circuits are specified for compliance
with recognized codes pertaining to X-ray emission. Conse-
quently, 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.Unautho-
rized modification can increase the high voltage value and
cause X-ray emission from the cathode ray tube.
(12) Crimp type wire connector
In 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 un-
avoidable, in order to prevent safety hazards, perform care-
fully 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).
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.
Fig.1-1-4
c) Align the lengths of the wires to be connected. Insert
the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, use the crimping tool to
crimp the metal sleeve at the center position. Be
sure to crimp fully to the complete closure of the
tool.
Fig.1-1-6
e) Check the four points noted in Fig.1-1-7.

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 compli-
ance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater be-
tween power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone 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 spec-
ified clearance distance (d), (d') between soldered termi-
nals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.
Fig.1-1-8
(4) Leakage current test
Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed ac-
cessible parts (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone 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.
Fig.1-1-9
(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.

SPECIFIC SERVICE INSTRUCTIONS
2.1 Manually removing the cassette tape
If you cannot remove the cassette tape which is loaded because
of any electrical or mechanical failures, manually remove it by
taking the following steps.
(1) Unplug the power cord plug from the power outlet.
(2) Refer to the disassembly procedure of the VCR and per-
form the disassembly of the major parts before removing
the mechanism assembly. (See Fig. 2-1a)
Fig.2-1a
Fig.2-1b
(3) Unload the pole base assembly by manually turning the
gear of the loading motor until the pole base assembly is
hidden behind the cassette lid. In doing so, hold the tape by
the hand to keep the slack away from any grease. (See
Fig.2-1b )
In case of mechanical failures, while keeping the ten-
sion arm assembly free from tension, pull out the tape
on the pole base assembly. Take the spring(a) of the
pinch roller arm assembly off the hook, and detach it
from the tape.
(4) Remove the screw (a) of the side frame (L/R).
(5) Hold the slack tape and cassette cover together, lift the
cassette tape, top frame, cassette holder and side frames
(L, R) together from the rear and remove them by dis-en-
gaging the hooks (a) and (b).
Fig.2-1c
(6) Take up the slack of the tape into the cassette. This com-
pletes removal of the cassette tape.
