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 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.
symbol and shaded ( ) parts are
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.

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.
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).

1.6 DISASSEMBLY OF 7 OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY

1.6.1 Precautions
1. Carefully handle the CCD image sensor, optical LPF, lens,
etc. during the disassembly work. Pay the most careful attention to the surface of those parts not to get it soiled, scratched or dusty. If some of those surfaces gets soiled with fingerprints, etc., wipe it out with silicone paper, clean chamois, cleaning cloth or the like.
2. The new CCD image sensor is occasionally shipped from
the factory as a protection seal is applied onto its transparent glass. If so, leave the protection seal as it is and remove it just before installing the CCD image sensor in the OP block assembly.
1.6.2 How to remove OP block assembly and CCD board
assembly
1. Unsolder at the two points (SD1) and remove the shield
case.
2. Unsolder at the sixteen points (SD2) and remove the CCD
board assembly.
3. Remove the two screws (1, 2) and then remove the CCD
base assembly.
Note6a:
Note6b:
Carefully remove the CCD base assembly, because the space rubber and optical LPF may be removed together with the CCD image sensor.
When replacing the CCD image sensor, don’t replace it individually but replace the CCD base assembly in whole with a new one.
1.6.3 How to install OP block assembly and CCD board assembly
1. Install the optical LPF with the space rubber fitted to its
CCD side in the OP block assembly.
2. Paying heed to the space rubber not to get it to come off
the setting position, install the CCD base assembly in place and fasten it together with the space rubber with the two screws (1, 2).
3. Set the CCD board assembly in the CCD base assembly,
and fasten it by soldering at the fourteen points (SD2).
4. Install the shield case and fasten it by soldering at the two
points (SD1).
1.6.4 Replacement of service parts

1.7 HOW TO TAKE OUT CASSETTE TAPE MANUALLY

1.7.1 How to remove cassette tape manually from the set
If the cassette tape is not ejected from the cassette housing because of some electric trouble, it can be removed from the set by the temporary measure that is to turn the loading motor forcibly as mentioned below.
Through the removing work, pay heed to the exterior parts such as the covers, etc. as well as to the cassette tape to get nothing damaged.
<Procedure>
1. Disconnect the power supply (battery or DC cord) from the set.
2. Dismantle the deck ope assy, front cover assembly referring to the section 1 (page 1-4, 1-5).
Note:
When and after dismantling the front assembly, pay careful attention to the internal components such as the OP block assembly (lens), battery terminal, etc. that are exposed after the front assembly is removed.
3. Open the cassette cover assembly completely and hold it open through the work.
4. Supply 3 V DC to the terminals (electrodes) on the top of the loading motor to slide the slide deck assembly to the front side, and stop the power supply when both the pole bases are positioned in the unloading status inside the tape. Since the tape remains as it is not wound up at that time, pay careful attention to the tape
not to damage it and not to soil it with grease, etc. If unloading operation is continued after both the pole bases return to their respective positions inside the tape, the mechanism enters the eject mode and the cassette housing assembly is lifted up. If it occures, the pulled­out tape may be caught in the cassette lid and the tape may be resultingly damaged.
5. Turn the center gear assembly with a sharp-pointed thing (chip IC replacing jig, etc.) in the direction of the arrow to wind up the tape. Carefully turn the center gear assem­bly not to damage the tape. If the tape cannot be wound up by turning the center gear assembly, it is thinkable that the idler arm assembly is positioned not to engage with the reel disk assembly. If so, shift the mechanism mode so that the idler arm assembly is correctly engaged with the reel disk assem­bly. After fine adjusting the engagement, try to wond up the tape is the same manner once more. In such the event, it is recommended to shift the idler arm assembly slightly in the loading direction.
6. After confirming that the tape is completely wound up, proceed with unloading operation until the mechanism enters the eject mode. Then, take the cassette tape out of the cassette housing.
7. After removing the cassette tape, check to see if the manually wound part of the tape is not soiled with grease, etc. At the same time, check the mechanism assembly, particularly the tape transport system, whether there is something abnormal or not.

2.2.2 Explanation of mechanism mode
The mechanism mode of this model is classified into six modes as shown in Table 2-2-1. Each mechanism mode can be distinguished from others by the relative position of Q mark on the sub cam gear to the inner or outer protrusion on the main deck. Refer to Fig. 2-2-2 to 2-2-7 below. The EJECT mode, C IN mode and SHORT FF mode should be recognized by the relative position of the Q mark to the inner protrusion, while the STOP mode, REV mode and PLAY mode should be recognized by that to the outer pro­trusion.

Note 7c:
Since the slide guide plate assembly controls the slide deck assembly so that it exactly slides the main deck assembly, it must exactly be assembled in the PLAY mode. Therefore, temporarily fix the slide guide plate assembly in this stage. For details of reassembling procedure, refer to 2.2.8 Assembling slide deck assembly and main deck as­sembly on page 2-15.
Note 7d:
The pad arm assembly controls the tension level of the ten­sion arm assembly. For adjustment of the tension arm as­sembly, refer to page 2-8.
Note 7e:
When reinstalling the load brake assembly, slightly lift the slide deck assembly upwards because the lower part of the load brake assembly sticks out of the slide deck assembly.

2.2.7 Checkup and adjustment of mechanism phase
<Rotary encoder> Set the “” of the rotary part at the tapped hole as shown in the figure.
<Worm wheel> (Note 2) Set the worm wheel so that its locating hole meets the hole on the main deck assembly.
<Main cam gear /Brake control plate> After fitting the main cam\ gear and brake control plat together,set them together so that their locating holes meet the hole on the main \ deck assembly.
<Connect gear> (Note 2) Set the connect gear so that its locating hole meets the hole on the main deck assembly.
Note 1
<Connect gear 2> (Note 2) Set the connect gear 2 so that its locating hole meets the hole on the main deck assembly.
<Sub cam gear> Set the sub cam gear so that its locating hole meets the hole on the main deck assembly. This state represents that the mechanism is in the EJECT mode, which is the “mechanism assembly mode”.
Note 1:
Since the connect gear 2 is tightly fixed to the main deck by caulking, adjust its phase with the connect gear and sub cam gear.
Fig. 2-2-24
Note 2:
The part that needs phase adjustment by the hole on the main deck assembly must exactly be set as the specified phase. There is a fear that some part is installed in a wrong phase because assembling of the mechanism is automated. If so, set every part in the correct phase whenever the mechanism is reassembled.
