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.

7. Observe that wires do not contact heat producing parts

8. Check that replaced wires do not contact sharp edged or

force in any direction will not loosen it.

Power cord

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.

(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.

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.

Up to 127 errors with composite video levels of 50mV or more can be corrected. No limitation of errors per line within 127 however, the maximum consecutive errors are 4 and the correction results may be inferior to the case of single error correction. Oblique noise may be observed on the screen during white blemish detection. This is due to the principles of error correction and is not a malfunction. White blemish can be detected in the following area.

(1) EEP-ROM and maintenance data

GY-HD100 is equipped with three EEP-ROMS for the purpose of data maintenance, and their contents are as per the following list. When the circuit board or EEP-ROM is replaced, there will be no data in the EEP-ROM. When the unit is powered up, and the SYSCON CPU recognizes that there is no data in the EEP-ROM, it automatically writes initial data into the EEP-ROM to initialize it. The memory data shown in Table 1-5-15 will all be reset back to default settings, so it will be necessary to perform necessary adjustments and settings again.

(2) IEEE1394 ID setting method

IEEE1394 equipped units have an ID, as defined by the IEEE1394 standard, stored in the internal EEP-ROM (IC 70. At the time of production, the ID numbers allotted to each individual unit are written into the unit’s memory, and a sticker bearing the ID is affixed inside the unit. When the EEP-ROM or MAIN circuit board is replaced, the ID needs to be set again.

Procedure for setting IEEE1394 ID The ID is an 8 digit, hexadecimal code, with 1 high-end Byte being the model code, and 3 low-end Bytes being unique to the unit. The model code is automatically initialized, so only the lower 3 Bytes of unique code need to be set manually. Go from Service Menu → OTHERS Menu → MEM. EDIT (Memory Edit) to select the address in the ID data section and make the setting directly. The 3 low-end Byte address is as follows. Make the setting while confirming the ID printed on the label (GY-HD100U/E ID: 4Fxxxxxx, GY-HD101E ID: 4Exxxxxx) pasted on the inside of the GY-HD100 (See Fig. 1-5-15).

2.4.3 Cleaning

The mechanism incorporates a video head cleaner that is effective for the removal of magnetic dust, etc. However, tape lubricant adhering to the head surface produces a spacing loss, it is recommended to polish the heads using a head cleaning tape. When the video heads become soiled an increase in the error rate results. Eventually, when the error rate increase is too much to be corrected by the error correction circuit, block noise will be observed in the picture.

1) Cleaning the video heads Use the DVC cleaning cassette for cleaning the video heads. Always be sure to use the cleaning cassette, Part No. MDV12CLAUX. The video heads should be cleaned periodically. Moreover, care should be taken about the operating environment as the tape running time standard varies accordingly. Please refer to “Precautions for Use of Head Cleaning Tape” in the instructions.

Caution  As the DVC cleaning tape has a much higher lap-

ping effect than VHS cleaning tapes, frequent use of the DVC cleaning tape will reduce the head service life. Do not play the DVC cleaning tape for more than 10 seconds per run or for more than 4 times per cleaning session.

 The cleaning tape can be used effectively for up to

about 4 passes. It cannot improve the cleaning effect even if it is run for more than 4 times.

3) Cleaning the tape transport system Moisten the tip of a cotton swab with alcohol and use it to clean the tape transport parts. Take special care of the TU/ SUP guide roller flanges and the rear sides of the inclined poles, as these are the parts that most frequently collect magnetic dust.

Caution Do not wipe the capstan shafts using alcohol. Otherwise, the oil in the bearings may be diluted by the alcohol and become attached to the tape.

Ta ke special care.

2) Cleaning the upper/lower drums Use a cleaning cloth or high-quality paper sheet to clean the upper drum. Moisten the cloth or paper sheet with a small amount of ethyl alcohol, apply it lightly against the upper drum while turning it by hand. After this operation, wipe it with a dry cloth or paper sheet without alcohol. Be sure to play the cleaning tape to its end. The lower drum tends to gather magnetic dust, etc. in its lead section, and linearity cannot be achieved if this becomes excessively dirty. The tape inlet and outlet areas are contaminated particularly easily, causing trouble such as dropout in FM signal reproduction, block noise on one side of a monitored picture, absence of audio output or incapability of time code readout. To clean the lead section, use a toothpick and rub lightly along the lead section. Be careful not to scratch the video head when this is done.

Table 2-4-2

1) Oiling should be performed periodically. Oil the shafts by referring to the maintenance table.

2) After replacing a part, grease the required points. For the parts to be greased see the exploded diagram in chapter 5, “DISASSEMBLY DRAWINGS AND PARTS LIST”.

3) As Hanal separates over time, be sure to mix it (shake) well before use.

4) Take care not to leave grease or oil on the tape transport parts which come into contact with the tape or on the brake pads.

5) Take care not to apply too much oil or grease. The standard oiling quantity is one drop and the standard greasing quantity is the quantity with which the grease does not overflow.

Note:

• Be sure to use a brand-new tape for this adjustment.

• Be sure to clean the drum with a head cleaning tape before adjustment.

• The error rate should be mesured with the Viterbi OFF. The Viterbi is set to OFF automatically when the adjustment mode is entered.

(1) Prior to the procedure below, prepare self-

recording tape. (2) Select "102. ME SP VCO" adjustment. (3) Play back the self recording tape, and decrease

the VR DATA to make the SBE waveform ab-

normal. (Fig. 3.5.2(2)) (Pressing the [STATUS]

button simultaneously with the JOG dial var-

ies the adjustment value by ±10 steps) (4) Increase the adjustment VR DATA little by lit-

tle, and define the point where the SBE wave-

form becomes normal as value "A". (Fig.

3.5.2(3))

(5) Increase the adjustment VR DATA to make

the SBE waveform abnormal. (Fig. 3.5.2(2)) (6) Decrease the adjustment VR DATA little by lit-

tle, and define the point where the SBE wave-

form becomes normal as "B". (Fig. 3.5.2(3)) (7) Calculate the intermediate value "C" between

the point A and the point B, and set the value

C. (Since the adjustment values are hex

number, use a functional computation-capa-

ble calculator or the PC calculator provided in

Accessories.)

Setting value C=(A+B)/2

(8) Confirm that the error rate value is 498 or

less in each channel. (9) Check the tolerance of adjustment. Shift the

adjustment value against the setting value by

±60h.

Conform that the error rate is 3,000 or less in

each channel. When the error rate is over

3,000, recheck the adjustment procedure

from (4).

(For example, when the adjustment value is

"9ED", ±60h is "A4D" and "98D". So, shift the

value to "A4D" and "98D", and check the tol-

erance of error rate adjustment.) (10) Return the adjustment value to the setting

value C, and Press the JOG dial to store the

adjustment data.
