SECTION 1
PRECAUTION
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
compliance with various regulations regarding spu-
rious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard.
Replace only with same type and rated fuse(s) as speci-
fied.
(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 compli-
ance with recognized codes pertaining to X-ray 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 cir-
cuits.Unauthorized modification can increase the high volt-
age 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 be-
tween the power cord and power trans former primary lead
wires are performed using crimp type connectors, if replac-
ing the connectors is unavoidable, in order to prevent safe-
ty 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 re-
use 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. In-
sert 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.

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 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 ex-
posed accessible parts. Use an AC voltmeter to measure
across both terminals of load Z. See Fig.1-1-9 and follow-
ing 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 Service position
This unit has been designed so that the Mechanism and Main
board assemblies can be removed together from the bottom
chassis. Before diagnosing or servicing the circuit boards, take
out the major parts from the bottom chassis.
2.1.1 How to set the "Service position"
(1) Refer to the disassembly procedure and perform the disas-
sembly of the major parts before removing the Mechanism
assembly.
(2) Remove the screws that fix the Mechanism, Main board as-
sembly to the bottom chassis. If any other screws are used
to fix the boards, remove them also.
(3) Remove the combined Mechanism, DVD unit, regulator,
digital, junction and Main board assemblies.
(4) If any other major parts are used, remove them also.
(5) Connect the wires and connectors of the major parts that
have been removed in steps (1) to (4). (Refer to Fig. 2-1a.)
(6) Place the combined Mechanism, Main board and other
board assemblies upside down.
(7) Insert the power cord plug into the power outlet and then
proceed with the diagnostics and servicing of the board as-
sembly.
Notes:
· Before inserting the power cord plug into the power out-
let, make sure that none of the electrical parts are able
to short-circuit between the workbench and the board
assembly.
· For the disassembly procedure of the major parts and
details of the precautions to be taken, see "Removing
the major parts".
· If there are wire connections from the Main board and
Mechanism assemblies to the other major parts, be sure
to remove them (including wires connected to the major
parts) first before performing step (2).
· When carrying out diagnosis and repair of the Main
board assembly in the "Service position", be sure to
ground both the Main board and Mechanism assem-
blies. If they are improperly grounded, there may be
noise on the playback picture or FDP counter display
may move even when the mechanism is kept in an inop-
erative status.
· In order to diagnose the playback or recording of the
cassette tape, set the Mechanism assembly to the re-
quired mode before placing it upside down. If the mech-
anism mode is changed (including ejection) while it is in
an upside down position the tape inside may be dam-
aged.
· For some models, the mechanism and board assem-
blies are attached by connectors only. When carrying
out a diagnosis or repair of the boards in the "Service
position", make sure that the connectors are not dis-
connected.
Fig.2-1a
2.2
Jig RCU mode
This unit uses the following two modes for receiving remote con-
trol codes.
(1) User RCU mode:Ordinary mode for use by the user.
(2) Jig RCU mode: Mode for use in production and servicing.
When using the Jig RCU, it is required to set the VCR to the Jig
RCU mode (the mode in which codes from the Jig RCU can be
received). As both of the above two modes are stored in the EE-
PROM, it is required to set the VCR back to the User RCU mode
each time that an adjustment is made or to check that the neces-
sary operations have been completed.These modes can be set
by the operations described below.
Note:
· When the unit is set to JIG mode and when the unit is
under JIG mode, the remote control unit attached to
product operates only in "Remote Control Code 1".
Since the unit is in "Remote Control Code 3" when it is
shipped and just after its batteries are changed, "Re-
mote Control Code 3" needs to be changed to "Remote
Control Code 1."
· Confirm the RCU mode when exchanged parts. Since
some SERVICE PARTS sets the VCR to the Jig RCU
mode as initial setting. Therefore please set the VCR to
the user RCU mode after replacing the EEPROM.
