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

Connector

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

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 0.069N

(2) While triggering the HID, observe the waveform of

ENV_OUT.
(3) Set the manual tracking mode (ATF OFF).
(4) Confirm that the waveform is entirely parallel and straight,

and free from remarkable level-down, through the tracking

operation.

Make the confirmation as follows if necessary.
(5) If level-down is observed on the left hand side of the

waveform, straighten the level by turning the GUIDE

ROLLER (SUP).

If level-down is observed on the right hand side of the

waveform, straighten the

level by turning the GUIDE ROLLER (TU).

For actual adjustment, first, turn both the GUIDE ROLL-

ERS (SUP and TU) to tightening direction (clockwise) in or-

der to misalign the waveform once.

Next, turn the GUIDE ROLLERS to returning direction

(counterclockwise), then stop turning at the point where the

waveform becomes flat.

Turn only the GUIDE ROLLER (SUP) further more, then

stop turning at the point where the waveform starts chang-

ing.
(6) After the adjustment, try the unloading motion once, and

confirm that the waveform is flat when the tape has been

played back again.
(7) Play back the self-recording.
(8) Confirm that the waveform is flat.

Whenever some abnormal signal is input to the syscon CPU, an
error number (E01, as an example) is displayed on the LCD
monitor or (in the electronic view finder).In every error status,
such the message as shown below alter nately appear over and

over.

• In an emergency mode, all operations except turning on/off the
POWER switch are ineffectual.

E01 LOADING In the case the encoder position is

not shifted to the next point though
the loading motor has rotated in the
loading direction for 4 seconds or
more. This error is defined as [E01].

E02 UNLOADING In the case the encoder position is

not shifted to the next point though
the loading motor has rotated in the
unloading direction for 4 seconds or

1. The mechanism is locked during mode shift.

2. The mechanism is locked at the mechanism loading end,
because the encoder position is skipped during
mechanism mode shift.

3. No power is supplied to the loading MDA.

1. The mechanism is locked during mode shift.

2. The mechanism is locked at the mechanism loading end,

mechanism mode shift.

more. This error is defined as [E02].

E03 TU & SUP REEL FG In the case no REEL FG is

produced for seconds shown in the
table below or more in the capstan
rotation mode after loading was
complete, the mechanism mode is
shifted to STOP with the pinch roller
set off. This error is defined as
[E03].However, no REEL EMG is
detected in the SLW/STILL mode.

E04 DRUM FG In the case there is no DRUM FG

input in the drum rotation mode for
4 seconds or more. This error is
defined as [E04], and the
mechanism mode is shifted to
STOP with the pinch roller set off.

1. The idler gear does not engage with the reel disk well.

2. Though the idler gear and reel disk are engaged with
each other, the tape is not wound because of overload
to the mechanism.

3. No FG pulse is output from the reel sensor.

4. No power is supplied to the reel sensor.

5. Tape transport operation takes place with a cassette
having no tape inside.

6. The tape slackens and no pulse is produced until the
slack is taken up and the tape comes into the normal
status.

1. The drum cannot be started or drum rotation is stopped
because tape transport load is too high.

1) Tape tension is extremely high.

2) The tape is damaged or soiled with grease, etc.

2. The DRUM FG signal is not received by the syscon CPU.

1) Disconnection in the middle of the signal line.

2) Failure of the DRUM FG pulse generator (hall

element).

3. No drum control voltage is supplied to the MDA.

4. No power is supplied to the DRUM MDA.

E06 CAPSTAN FG In the case no CAPSTAN FG is

produced in the capstan rotation
mode for 2 seconds or more. This
error is defined as [E06], and the
mechanism mode is shifted to
STOP with the pinch roller set
off.However, no CAPSTAN EMG is
detected in the STILL/FF/REW
mode.

1. The CAPSTAN FG signal is not received by the syscon
CPU.

1) Disconnection in the middle of the signal line.

2) Failure of the CAPSTAN FG pulse generator (MR

element).

2. No capstan control voltage is supplied to the MDA.

3. The capstan cannot be started or capstan rotation is
stopped because tape transport load is too high.

1) Tape tension is extremely high. (Mechanical locking)

2) The tape is damaged or soiled with grease, etc. (Tape

tangling occurs, etc.)
