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 Tape 3) Spacers 5) Barrier
2) PVC tubing 4) 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.

DISASSEMBLY

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions
1. Be sure to remove the power supply unit prior to mount­ing and soldering of parts.
2. When removing a component part that needs to discon­nect the connector and to remove the screw for remov­ing itself, first disconnect the connecting wire from the connector and then remove the screw beforehand.
3. When connecting and disconnecting the connectors, be careful not to damage the wire.
4. Carefully remove and handle the part to which some spacer or shield is attached for reinforcement or insula­tion.
5. When replacing chip parts (especially IC parts), desolder completely first (to prevent peeling of the pattern).
6. Tighten screws properly during the procedures. Unless specified otherwise, tighten screws at a torque of 0.078N
m(0.8kgf•cm).

1.7 EMERGENCY DISPLAY

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 alternately appear over and over.
In an emergency mode, all operations except turning on/ off the POWER switch are ineffectual.

Details
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].
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 more. This error is defined as [E02].
In the case no REEL FG is produced for 4 sec­onds 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 SLOW/STILL mode.
Example (in case of the error number E01):
E01 UNIT IN SAFEGUARD MODE
E01 REMOVE AND REATTACH BATTERY
Possible cause
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, because the encoder position is skipped during mechanism mode shift.
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.

1.8 SERVICE KNOW-HOW

When performing disassembly/assembly work to this model, the parts that are most complicated and require special at­tention are the E. VF unit and the OP MDA board, OP block and shoe assemblies, all of which are mounted inside the lower case assembly. Care should be taken in handling these parts as they are mounted inside the lower case assembly (except the E.VF unit) and there is a lack of adequate space to work conven­iently. This section gives further details regarding the disas­sembly procedures, although they have been described in previous sections.
