Important Safety Precautions

Connector

Metal sleeve

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.

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.

Fig.2

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.

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.

Chassis

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.

1.8 TAPE EJECTION IN CASE OF EMERGENCY

When the cassette tape cannot be ejected normally, take it out by the following methods.

1.8.1 Tape Ejection Using Forced Eject Mode (Short-circuiting of Internal TP)

GY-DV500 is provided with a compulsory eject mode for use in case the button operations are not accepted due to a malfunction of the mechanism control circuitry. When an attempted operation of the operation buttons is not accepted, set the compulsory eject mode as described below before removing the tape.

CAUTION

䡲 This mode is effective only when the electrical and me-

chanical systems of the mechanism unit are normal and a tape ejection operation is not accepted due to a problem of the electrical system.

䡲 If there is a problem in the mechanical system of the unit,

this mode may be ineffective. If compulsory ejection is performed in such a case, the tape could be damaged or cut.

(1) Remove the left side cover (see section 1.2.1). (2) With the power supply on, short-circuit TP107 on the DV

MAIN board with the GND using a wire, etc.

(3) Forced ejection is activated to eject the tape.

(3) Apply 3 V DC to the electrodes at the top of the loading

motor (red wire to + pole, brown wire to - pole) to unload the tape. Unload it little by little because it could be damaged or contaminated by grease if the pole base assemblies are returned completely beyond the position of the tape.

Brown wire

Red wire

Fig. 1-8-2(1)

(4) If the tape slackens, take it up by rotating the shaft at the

top of the capstan motor in the direction of the arrow using a sharp-tipped object (chip IC replacement tool, etc.).

(5) Repeat steps (3) and (4) above until the tape is taken up

completely.

(6) After confirming that the tape has been taken up completely,

rotate the gear of the cassette housing assembly in the direction of the arrow in order to eject the cassette tape.

1.8.2 Tape Ejection without Using the Forced Eject Mode

Activate the loading motor by applying DC voltage to its two terminals.

NOTE

When a forced ejection is not accepted because the loaded cassette tape cannot be ejected due to a fault in the electrical system or because of some problem in the mechanism unit, eject the tape by using the following procedure. However, as this mode drives the loading motor, it assumes that the mechanical system is operating normally.

(1) Turn off the power supply to the unit. (2) Flip open the DV MAIN board to expose the mechanism

(see section 1.6.3).

1-10

1.8.3 Manual Tape Ejection

If the loading motor cannot be run by the procedure outlined in section 1.8.2, the mechanism may be defective. When the loading motor is defective, remove the tape as described below.

(1) Remove the mechanism unit from the main unit. See sec-

tion 1.6.2 for the removal method.

(2) After removing the mechanism unit, remove the DV MAIN

board (see section 1.6.3).

(3) Remove the 2 screws and remove the active head cleaner

assembly (see section 1.7.2). (4) Remove the side cover to easy operation (see section 1.7.2). (5) Remove the 2 screws and remove the rear panel from the

side of the PR & MDA board.

Carefully unplug the wires so as not to damage them, then

remove the PR & MDA board (see section 1.7.2).

(10) The pole base assemblies should be unloaded little by lit-

tle. If they are returned completely beyond the position of the tape, the tape may slacken and become damaged or stained by grease.

(11) If the tape slackens, take it up by rotating the shaft on the

top of the capstan motor in the direction of the arrow using a sharp-tipped object (chip IC replacement tool, etc.) (see section 1.8.2-(4)).

(12) Repeat steps (9) and (10) above until the tape is taken up

completely.

(13) After confirming that the tape has been taken up com-

pletely, tighten the cassette housing retaining screws which were loosened in step (6).

(14) Attach and clamp the cassette housing again, then rotate

the gear of the housing assembly in the direction of the arrow to eject the cassette tape in the same way as in section 1.8.2-(6).

1.9 CAUTION FOR REPLACING THE DV MAIN BOARD AND VIDEO SYSCON BOARD

When the DV MAIN board or VIDEO SYSCON board has been replaced for servicing, be sure to enforce the following items.

1.9.1 DV MAIN Board

[A] About the ID Management Label

Each VCR unit carries an ID label in compliance with IEEE1394 showing the unique ID assigned on the production line. (See the following figure for the label position.) When replacing the DV MAIN board, remove the ID management label that was provided originally with the unit from the defective board and attach it in the same position to the new board.

DV MAIN board

[B] Load EEPROM Internal Data

The EEPROM provided with the new board for replacement contains no data, while the EEPROM originally provided with the VCR unit contains the IEEE1394 ID data as well as all adjustment data written in the assembly and adjustments written on the production line. This means that the new VCR unit will not function if the new EEPROM is used in the condition in which it is delivered. When replacing the DV MAIN board, load the internal data of the EEPROM on the original board to the EEPROM of the new board.

(1) How to use original EEPROM to new DV MAIN board.

Remove the EEPROM from the original DV MAIN board, and attach the chip to the new board.

(2) How to write data from the original board to the new

EEPROM How to load all parameters in EEPROM on original board to new EEPROM by using the adjustment software. (For details, see section 3.7.13)

(3) In case of original EEPROM on the original DV MAIN board

was broken. Load the default data before making adjustments with the adjustment software, write the data in the new EEPROM, then make adjustments by following the adjustment procedures. (See section 3.7.12 for details.) And then, input the ID number on the original board to new EEPROM by using the adjustment software. (See section

3.7.13 for details.)

ID Label

Fig. 1-9-1

1.9.2 VIDEO SYSCON Board

[A] Transporting of IC407 (EEPROM) Data

When the SSF function is used, the cassette number recorded on tape (see section 9.4.1) has the model ID code appended to it. The model ID code is written in IC407 (EEPROM). However, as the new EEPROM mounted on the new replacement circuit board does not have the ID code written into it, the SSF function cannot work normally (the model ID code should be written in IC407 for the correct operation of the SSF function). Nevertheless, no means is provided for transporting the model ID code from the original EEPROM to the new EEPROM. Therefore, it is recommended to remove the original IC from the original board and mount it on the new board.

[B] ID Management Label

An ID management label is attached to the camera head. For the position, see Fig. 1-4-1.

(3) Character mixing (S901-4)

Set S901-4 to ON to superimpose the same characters as those displayed on the viewfinder-screen in the output signal from the TEST OUT terminal. This is a convenient facility for adjustment because the adjustment menu and screen can be displayed on an external monitor.

(4) Color-matrix adjustment (S901-6)

Set S901-6 to ON to view the color-matrix adjustment-mode screen on the Viewfinder-screen. This mode makes it possible to set color-matrix parameters in details (see section 1.12).

* Note that the color-matrix adjustment is not a normal adjust-

ment item. It is usually not required to adjust the color-matrix because this has been set to the optimum level before shipment.

* In case a color-matrix adjustment becomes necessary be-

cause of a user’s request, it should be performed in accordance with the description in section 1.2.

(5) Setup (S901-7): NTSC only

Set S901-7 to ON or OFF to select whether or not the output signal setup is included in the TEST OUT and MONITOR OUT terminals output. (Note that the signal recorded onto tape is not affected by the position of this switch. The signal is always recorded without the setup information.) As changing the position of this switch does not alter the signal level, it is not necessary to re-adjust the signal recording according to the position of this switch. This switch is effective only on the camera video output. With the video signal obtained by playing back a previously recorded tape, whether the setup is included or not can be selected with the item “SETUP” in the Service Menu (see section 1.13.3).

(6) Function setting (S901-8)

This switch is used to set the functions shown in Table 1-91(2). This switch is usually used to switch the defaults of the domestic and export-oriented models.

1.11.6 EEPROM in Camera

IC905 on the CAM1 board is an electrically erasable/rewritable EEPROM. It stores the following data.

䡲 Camera adjustment data set in the adjustment mode. 䡲 Settings in [CAMERA MENU]. 䡲 White blemish position coordinate data for use in white blem-

ish correction.

䡲 Auto white balance control data (A/B). 䡲 Camera status at the last power OFF (positions of non-lock

type switches, etc.).

Therefore, when retention of the above data becomes impossible due to a failure in the EEPROM or over the 1 million times of rewrite count, the EEPROM should be replaced with a new one and the data should then be re-set in it.

1.11.7 Tripod base

See the KA-510U servide manual NO. 60065 for servicing. The tripod is not exactly same as KA-510U. See note for the difference.

Note

These 1/4 and 3/8 inch fixing tripod holes are not povided for the KA-510U.

1.12 CHANGING THE COLOR MATRIX SETTING

NOTE

The color reproduction properties of the color-matrix circuit built into the DSP can be re-set by varying the values of 9 parameters. However, as these parameters have been set at the factory to the default values based on detailed studies of the product development process, it is usually not recommended to alter them. Note that this adjustment is not a normal electrical adjustment item. Should a re-adjustment of the color matrix (a color reproducibility change) be required as a result of a user request, etc., this should be performed only after studying and understanding the details of the following instructions.

1.12.1 Setting the Color Matrix

Preparation

The color matrix setting requires a color chart for use as a reference for color reproduction and a vectorscope. As we do not specify a color chart for this purpose, discuss the matter with any user requesting a custom setting and use a color chart to be agreed by the user.

Adjustment

The color-matrix circuit can be set using menus displayed on the screen (the viewfinder-screen or the test out screen).
