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

1.6 DISASSEMBLY OF # 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. Remove the spacer.

2. Unsolder at the fourteen points (SD1) and remove the CCD board assembly.

3. Remove the two screws (1, 2) and then remove the CCD base assembly.

Note

a:

Carefully remove the CCD base assembly, be-

#

cause the space rubber and optical LPF may be removed together with the CCD image sensor.

Note#b:

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 # OP block assembly.

2. With the spacer rubber left attached to the CCD base assembly, install the assembly in the OP block assembly and clamp it using 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 (SD1).

1.6.4 Replacement of service parts

Service parts to be supplied for the OP block assembly are as follows. When replacing a part, be very careful not to get the FPC wire broken or damaged by soldering (overheating).

1. Focus motor

2. Zoom motor

3. Iris motor unit

Note

c:

When soldering the FPC wire of the focus motor

#

or zoom motor during the replacement work, be sure to keep the tip of a soldering iron approximately 1 mm above the terminal.

Note#d:

The iris motor unit includes one FPC assembly and two sensors.

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.

E04 DRUM FG

E05 –

E06 CAPSTAN 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.

–

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.

Table 1-7-1

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.

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 EVF unit and the AUDIO 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.

1. See Fig. 1-8-1. (1) Remove the hood by moving the 0 microphone out of

way.

(2) Peel off the spacer, remove the screw (32) and take out

the # OP block assembly by moving the 0 microphone out of the way.

(3) Remove the screw (33) and, while opening the @ AU-

DIO board assembly, disconnect the wire from the connector (CN203) and remove the 0 microphone.

(4) Remove the screw (34), peel off the spacer, take out

the ! E.VF assembly by moving the $ shoe assembly out of way, disconnect the FPC from the connector (CN204).
