Important Safety 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.
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 com-
ply 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:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
5. Use specified insulating materials for hazardous live parts. Note
especially:
1) Insulation Tape3) Spacers5) Barrier
2) PVC tubing4) Insulation sheets for transistors
6. When replacing AC primary side components (transformers, power
cords, noise blocking capacitors, etc.) wrap ends of wires securely
about the terminals before soldering.
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 transformer 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.
1) Connector part number : E03830-001
2) Required tool : Connector crimping tool of the proper type which
will not damage insulated parts.
3) Replacement procedure
(1) 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.3
(2) 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
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.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 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.
Fig.4
(3) Align the lengths of the wires to be connected. Insert the
wires fully into the connector.

(4) As shown in Fig.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.

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 table 1 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 table 1
below.
Fig. 8
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 figure 9 and following
table 2.

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 figure 10 and grounding specifications.

Head clog warning
When the mechanism mode cannot be changed to another mode even when the loading motor has rotated
for more than 4 seconds in the loading direction, [E:01]
is identified and the power is turned off.
When the mechanism mode cannot be changed to another mode even when the loading motor has rotated
for more than 4 seconds in the unloading direction, [E:02]
is identified and the power is turned off.
When the take-up reel pulse has not been generated for
more than 4 seconds in the capstan rotating mode, [E:03]
is identified, the pinch rollers are turned off and stopped,
and the power is turned off. However, the reel EMG is
not detected in STILL/SLOW modes.
When the drum FG pulse has not been input for more
than 3 seconds in the drum rotating mode, [E:04] is identified, the pinch rollers are turned off and stopped, and
the power is turned off.
When the eject operation does not complete in 3 seconds after the start, [E:05] is identified, the pinch rollers
are turned off and stopped, and the power is turned off.
When the cassette insertion operation does not complete
in 3 seconds after the start, the cassette is ejected. In
addition, when the operation does not complete within
3 seconds after the start, [E:05] is also identified and the
power is turned off immediately.
When the capstan FG pulse has not been generated for
more than 1 second in the capstan rotating mode, [E:06]
is identified, the pinch rollers are turned off and stopped,
and the power is turned off.However, the capstan EMG
is not detected in STILL/SLOW/FF/REW modes.
When short-circuiting of the SW power supply with GND
has lasted for 0.5 second or more, [E:07] is identified,
all the motors are stopped and the power is turned off.
When DD tilting does not complete in 4 seconds, [E:08]
is identified, the tilt motor is stopped and the power is
turned off.
When the DD FG pulse is not generated within 2.5 seconds, [E:09] is identified, the tilt motor is stopped and
the power is turned off.
When the supply reel pulse has not been generated for
more than 10 seconds in the capstan rotating mode,
[E:0A] is identified and the cassette is ejected (but the
power is not turned off). However, note that the reel EMG
is not detected in the SLOW/STILL mode.
Presupposing the presence of the control pulse output in the PLAY mode, when the value obtained by mixing the two V.FM output
channels (without regard to the A.FM output) has remained below a certain threshold level for more than 10 seconds, [E:C1] or [E:U1]
is identified and recorded in the emergency history. During the period in which a head clog is detected, the FDP and OSD repeat the
“3-second warning display” and “7-second noise picture display” alternately.
EMG code : “E:C1” or “E:U1” / FDP : “U:01” / OSD : “Try cleaning tape.” or “Use cleaning cassette.”
The head clog warning is reset when the above-mentioned threshold has been exceeded for more than 2 seconds or the mode is
changed to another mode than PLAY.
The mechanism is locked in the middle of mode transition.

1
The take-up reel pulse is not generated in the FWD transport modes (PLAY/
FWD SEARCH/FF, etc.) because;
1) The idler gear is not meshed with the take-up reel gear;
The idler gear is meshed with the take-up reel gear, but incapable of wind-
2)
ing due to too large mechanical load (abnormal tension);
3) The take-up reel sensor does not output the FG pulse.
2
The supply reel pulse is not generated in the REV transport modes (REV
SEARCH/REW, etc.) because;
1) The idler gear is not meshed with the supply reel gear.
2) The idler gear is meshed with the supply reel gear, but incapable of winding due to too large a mechanical load (abnormal tension);
3) The supply reel sensor does not output the FG pulse.
3
Power is not supplied to the reel sensors.
1
The drum could not start or the drum rotation has stopped due to too large
a load on the tape, because;
1) The tape tension is abnormally high;
The tape is damaged or a foreign object (grease, etc.) adheres to the tape.
2)
2
The drum FG pulse did not reach the System controller CPU because;
1) The signal circuit is disconnected in the middle;
2) The FG pulse generator (hall device) of the drum is faulty.
3
The drum control voltage (DRUM CTL V) is not supplied to the MDA.
4
Power is not supplied to the drum MDA.
1
The cassette cannot be ejected due to a failure in the drive mechanism of
the housing.
2
When the housing load increases during ejection, the loading motor is
stopped because of lack of headroom in its drive torque.
Housing load increasing factors: Temperature environment (low temperature, etc.), mechanism wear or failure.
3
The sensor/switch for detecting the end of ejection are not functioning normally.
4
The loading motor drive voltage is lower than specified or power is not supplied to the motor (MDA).
5
When the user attempted to eject a cassette, a foreign object (or perhaps
the user's hand) was caught in the opening of the housing.
1
The capstan could not start or the capstan rotation has stopped due to too
large a load on the tape, because;
1) The tape tension is abnormally high (mechanical lock);
2) The tape is damaged or a foreign object (grease, etc.) is adhered to the
tape (occurrence of tape entangling, etc.).
2
The capstan FG pulse did not reach the System controller CPU because;
1) The signal circuit is disconnected in the middle;
2) The FG pulse generator (MR device) of the capstans is faulty.
3
The capstan control voltage (CAPSTAN CTL V) is not supplied to the MDA.
4
Power is not supplied to the capstan MDA.
1
The SW 5 V power supply circuit is shorted with GND.
2
The SW 12 V power supply circuit is shorted with GND.
1 The absolute value sensor is defective. (The soldered parts have separated.)
2 The pull-up resistor at the absolute sensor output is defective. (The soldered parts
have separated.)
3 Contact failure or soldering failure of the pins of the connector (board-to-board) to the
absolute value sensor.
The absolute value sensor data is not sent to the System Controller CPU.
4
1 The FG sensor is defective. (The soldered parts have separated.)
2 The pull-up resistor at the FG sensor output is defective. (The soldered parts have

3 Contact failure or soldering failure of the pins of the connector (board-to-board) to the FG sensor.
4 The power to the sensor is not supplied. (Connection failure/soldering failure)
5 The FG pulse is not sent to the System Controller CPU.
The tilt motor is defective. (The soldered parts have separated.)
6
7 The drive power to the tilt motor is not supplied. (Connection failure/soldering failure)
8 The tilt motor drive MDA - IC is defective.
9 Auto-recovery of the DD tilting cannot take place due to overrun.
The supply reel pulse is not generated in the FWD transport mode (PLAY/
1
FWD SEARCH/FF, etc.) because;
1) PLAY/FWD or SEARCH/FF is started while the tape in the inserted cassette is cut in the middle;
2) A mechanical factor caused tape slack inside and outside the supply
reel side of the cassette shell. In this case, the supply reel will not rotate
until the tape slack is removed by the FWD transport, so the pulse is not
generated until then;
3) The FG pulse output from the supply reel sensor is absent.
2
The take-up reel pulse is not generated in the REV transport mode (REV
SEARCH/REW, etc.).
1) REV SEARCH/REW is started when the tape in the inserted cassette
has been cut in the middle;
2) A mechanical factor caused tape slack inside and outside the take-up
reel side of the cassette shell. In this case, the supply reel will not rotate
until the tape slack is removed by the REV transport, so the pulse will
not be generated until that time;
3) The FG pulse output from the take-up reel sensor is absent.
3
The power to a reel sensor is not supplied.
