Important Safety Precautions

cut close to connector

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).

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.

(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.

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.

Externally exposed accessible part

Z V

Fig. 9

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.

If the mechanism mode does not change to the next mode within 4 seconds after the loading motor starts rotating in the loading direction, while the mechanism is in the after-loading position (with the tape up against the pole base), [E:01] is identified and the power is switched OFF. However, if the tape loading is not completed within 4 seconds after the loading motor starts rotating in the loading direction, the tape is simply unloaded and ejected. No EMG data is recorded in this case.

When the mechanism mode cannot be changed to another mode even when the loading motor has rotated for more than 4 seconds in the unloading direction, [E:02] is identified and the power is turned off.

When the falling edje of the take-up reel pulse has not been generated for more than 4 seconds in the capstan rotating mode, [E:03] is identified, the pinch rollers are turned off and stopped, and the power is turned off. In this case, however, the mechanism should be in position after tape loading. Note that the reel EMG is not detected during Slow/Frame advance operations.

When the drum FG pulse has not been input for more than 3 seconds in the drum rotating mode, [E:04] is identified, the pinch rollers are turned off and stopped, and the power is turned off.

If the cassette does not reach the eject position within about 0.7 seconds after the cassette housing has started the cassette ejection operation, [E:05] is identified, the drive direction is reversed to load the tape, the mode is switched to STOP mode with the pinch roller OFF, and the power is switched OFF. During the cassette insertion process, the drive direction is reversed and the cassette is ejected if the tape is not up against the pole base within about 3 seconds after the start of the cassette pullingin operation. If the cassette does not reach the eject position within about 0.7 seconds after the drive mode reversal operation, [E:05] is identified and the power is switched OFF immediately.

When the capstan FG pulse has not been generated for more than 1 second in the capstan rotating mode, [E:06] is identified, the pinch rollers are turned off and stopped, and the power is turned off.However, the capstan EMG is not detected in SLOW/ STILL modes. Note that, if the part number of the System Control IC begins with “MN” or “M3”, the capstan EMG is not detected even during the FF/REW operation.

When short-circuiting of the SW power supply with GND has lasted for 0.5 second or more, [E:07] is identified, all the motors are stopped and the power is turned off.

When DD tilting does not complete in 4 seconds, [E:08] is identified, the tilt motor is stopped and the power is turned off.

When the DD FG pulse is not generated within 2.5 seconds, [E:09] is identified, the tilt motor is stopped and the power is turned off.

When the falling edge of the supply reel pulse has not been generated for more than 10 seconds in the capstan rotating mode, [E:0A] is identified and the cassette is ejected (but the power is not turned off). In this case, however, the mechanism should be in the position after tape loading (with the tape up against the pole base). Also note that the reel EMG is not detected during Slow/ Frame advance operations.

Presupposing the presence of the control pulse output in the PLAY mode, when the value obtained by mixing the two V.FM output channels (without regard to the A.FM output) has remained below a certain threshold level for more than 10 seconds, [E:U1] is identified and recorded in the emergency history. During the period in which the head clog is detected, the FDP shows "U:01" and the OSD repeats the “3 seconds of warning display” and the “7 seconds of noise picture display” alternately.

EMG code : “E:C1” or “E:U1” / FDP : “U:01” / OSD : “Try cleaning tape.” or “Use cleaning cassette.” The head clog warning is reset when the above-mentioned threshold has been exceeded for more than 2 seconds or the mode is changed to another mode than PLAY.

1. The mechanism is locked in the middle of the mode transition during a tape loading operation. The mechanism overruns during the tape loading operation because the SYSCON cannot recognize

2. the mechanism mode normally. This problem is due to a cause such as a rotary encoder failure.

Power is not supplied to the loading MDA. (M12V/Vcc/Vref/ICP are disconnected in the middle.)

The mechanism is locked in the middle of mode transition.

Without an eject signal being sent from the SYSCON, unloading is attempted (i.e. Ejection is attempted while the tape is still inside the mechanism.) because the SYSCON cannot recognize the mechanism mode normally. This is due to a cause such as a rotary encoder failure. (Mechanism position: UPPER)

Power is not supplied to the loading MDA. (M12V/Vcc/Vref/ICP are disconnected in the middle.)

The take-up reel pulse is not generated in the FWD transport modes (PLAY/FWD SEARCH/FF, etc.) because;

1)The idler gear is not meshed with the take-up reel gear because the mechanism mal-

functions for some reason.

The idler gear is meshed with the take-up reel gear, but incapable of winding due to

too large mechanical load (abnormal tension);

3)The reel is rotating normally but an FG pulse is not generated due to the take-up reel

sensor failure.

The supply reel pulse is not generated in the REV transport modes (REV SEARCH/ REW, etc.) because;

1) The idler gear is not meshed with the supply reel gear because the mechanism mal-

functions for some reason.

2) The idler gear is meshed with the supply reel gear, but incapable of winding due to

too large a mechanical load (abnormal tension);

3) The reel rotates normally but the FG pulse is not generated due to a supply reel

sensor failure.

Power(SW5V) is not supplied to the reel sensor on the tape winding side.

The drum could not start or the drum rotation has stopped due to too large a load on the tape, because;

1) The tape tension is abnormally high;

The tape is damaged or a foreign object (grease, etc.) adheres to the tape.

The drum FG pulse did not reach the System controller CPU because;

1) The signal circuit is disconnected in the middle;

2) The FG pulse generator (hall device) of the drum is faulty.

The drum control voltage (DRUM CTL V) is not supplied to the MDA.

Power (M12V) is not supplied to the drum MDA.

The cassette cannot be ejected due to a failure in the drive mechanism of the housing.

When the housing load increases during ejection, the loading motor is stopped because of lack of headroom in its drive torque.

Housing load increasing factors: Temperature environment (low temperature, etc.), mechanism wear or failure.

The sensor/switch for detecting the end of ejection are not functioning normally.

The loading motor drive voltage is lower than specified or power (M12V) is not supplied to the motor (MDA).

When the user attempted to eject a cassette, a foreign object (or perhaps the user's hand) was caught in the opening of the housing.

The capstan could not start or the capstan rotation has stopped due to too large a load on the tape, because;

1) The tape tension is abnormally high (mechanical lock);

2) The tape is damaged or a foreign object (grease, etc.) is adhered to the tape (occur-

rence of tape entangling, etc.).

The capstan FG pulse did not reach the System controller CPU because;

1) The signal circuit is disconnected in the middle;

2) The FG pulse generator (MR device) of the capstans is faulty.

The capstan control voltage (CAPSTAN CTL V) is not supplied to the MDA.

Power (M12V, SW5V) are not supplied to the capstan MDA.

The SW 5 V power supply circuit is shorted with GND.

The SW 12 V power supply circuit is shorted with GND.

1. The absolute value sensor is defective. (The soldered parts have separated.)

2. The pull-up resistor at the absolute sensor output is defective. (The soldered parts have separated.)

3. Contact failure or soldering failure of the pins of the connector (board-to-board) to the absolute value sensor. The absolute value sensor data is not sent to the System Controller CPU.

1. The FG sensor is defective. (The soldered parts have separated.)

2. The pull-up resistor at the FG sensor output is defective. (The soldered parts have separated.)

3. Contact failure or soldering failure of the pins of the connector (board-to-board) to the FG sensor.

4. The power (5V) to the sensor is not supplied. (Connection failure/soldering failure)

5. The FG pulse is not sent to the System Controller CPU. The tilt motor is defective. (The soldered parts have separated.)

7. The drive power to the tilt motor is not supplied. (Connection failure/soldering failure)

8. The tilt motor drive MDA - IC is defective.

9. Auto-recovery of the DD tilting cannot take place due to overrun. The supply reel pulse is not generated in the FWD transport mode (PLAY/FWD

1. SEARCH/FF, etc.) because;

1) PLAY/FWD or SEARCH/FF is started while the tape in the inserted cassette is cut in

the middle;

2) A mechanical factor caused tape slack inside and outside the supply reel side of the

cassette shell. In this case, the supply reel will not rotate until the tape slack is removed by the FWD transport, so the pulse is not generated until then;

3) The reel is rotating normally but the FG pulse is not generated due to a supply reel

sensor failure.

The take-up reel pulse is not generated in the REV transport mode (REV SEARCH/ REW, etc.).

1) REV SEARCH/REW is started when the tape in the inserted cassette has been cut

in the middle;

2) A mechanical factor caused tape slack inside and outside the take-up reel side of

the cassette shell. In this case, the supply reel will not rotate until the tape slack is removed by the REV transport, so the pulse will not be generated until that time;

3) The reel is rotating normally but the FG pulse is not generated due to a take-up reel

sensor failure.

The power (SW 5V) to a reel sensor is not supplied.

1.4 Service position

This unit has been designed so that the Mechanism and Main board assemblies can be removed together from the chassis assembly. Before diagnosing or servicing the circuit boards, take out the major parts from the chassis assembly.

1.4.1 How to set the “Service position”

(1) Refer to the disassembly procedure and perform the dis-

assembly of the major parts before removing the Mechanism assembly.

(2) Remove the screws that fix the Mechanism assembly to the

Chassis assembly. If any other screws are used to fix the boards, remove them also.

(3) Remove the combined Mechanism and Main board assem-

blies. (4) If any other major parts are used, remove them also. (5) Connect the wires and connectors of the major parts that

have been removed in steps (1) to (4). (Refer to Fig. 1-2-2d.) (6) Place the combined Mechanism, Main board and other

board assemblies upside down. (7) Insert the power cord plug into the power outlet and then

proceed with the diagnostics and servicing of the board as-

sembly.

Notes:

Before inserting the power cord plug into the power out-

•

let, make sure that none of the electrical parts are able to short-circuit between the workbench and the board assembly.

•

For the disassembly procedure of the major parts and details of the precautions to be taken, see “1.2 Removing the major parts”.

•

If there are wire connections from the Main board and Mechanism assemblies to the other major parts, be sure to remove them (including wires connected to the major parts) first before performing step (2).

•

When carrying out diagnosis and repair of the Main board assembly in the “Service position”, be sure to ground both the Main board and Mechanism assemblies. If they are improperly grounded, there may be noise on the playback picture or FDP counter display may move even when the mechanism is kept in an inoperative status.

•

In order to diagnose the playback or recording of the cassette tape, set the Mechanism assembly to the required mode before placing it upside down. If the mechanism mode is changed (including ejection) while it is in an upside down position the tape inside may be damaged.

•

For some models, the mechanism and board assemblies are attached by connectors only. When carrying out a diagnosis or repair of the boards in the “Service position”, make sure that the connectors are not disconnected.

1.5 Jig RCU mode

This unit uses the following two modes for receiving remote control codes.

1) User RCU mode : Ordinary mode for use by the user.

2) Jig RCU mode : Mode for use in production and servicing.

When using the Jig RCU, it is required to set the VCR to the Jig RCU mode (the mode in which codes from the Jig RCU can be received). As both of the above two modes are stored in the EEPROM, it is required to set the VCR back to the User RCU mode each time that an adjustment is made or to check that the necessary operations have been completed. These modes can be set by the operations described below.

1.5.1 Setting the Jig RCU mode

(1) Unplug the power cord plug from the power outlet. (2) Press and hold the “REC” and “PAUSE” buttons on the VCR

simultaneously, while plugging the power cord plug into the power outlet. When the VCR is set to the Jig RCU mode, the symbols ( “ : ” ) in the time display of the FDP are turned off.

1.5.2 Setting the User RCU mode

(1) Turn off the power. (2) Press the “REC” and “PAUSE” buttons of the VCR simulta-

neously. Alternatively, transmit the code “80” from the Jig RCU.

1.6 Mechanism service mode

This model has a unique function to enter the mechanism into every operation mode without loading of any cassette tape. This function is called the “Mechanism service mode”.

1.6.1 How to set the “Mechanism service mode”

(1) Set the VCR to the Jig RCU mode (the mode in which codes

from the Jig RCU can be received). (2) Transmit the code “E5” from the Jig RCU. (3) Release the lug of the Cassette holder and then slide the

Cassette holder toward the direction where the Cassette

holder is loaded by manually. (4) The cassette holder lowers and, when the loading has com-

pleted, the mechanism enters the desired mode. When the VCR is set to the Mechanism service mode, the

symbols (“Timer”) in the FDP (LED) are blinked.

1.6.2 How to exit from the "Mechanism service mode"

(1) Unplug the power cord plug from the power outlet.

1.7 Maintenance and inspection

1.7.1 Cleaning

Regular cleaning of the transport system parts is desirable but practically impossible. So make it a rule to carry out cleaning of the tape transport system whenever the machine is serviced. When the video head, tape guide and/or brush get soiled, the playback picture may appear inferior or at worst disappear, resulting in possible tape damage.

Note:

Absolutely avoid sweeping the upper drum vertically as

•

this will cause damage to the video head.

(1) When cleaning the upper drum (especially the video head),

soak a piece of closely woven cloth with alcohol and while holding the cloth onto the upper drum by the fingers, turn the upper drum counterclockwise.

(2) To clean the parts of the tape transport system other than

the upper drum, use a piece of closely woven cloth or a cotton swab soaked with alcohol.

(3) After cleaning, make sure that the cleaned parts are com-

pletely dry before using the cassette tape.

Fig. 1-7-1a

1.7.2 Lubrication

With no need for periodical lubrication, you have only to lubricate new parts after replacement. If any oil or grease on contact parts is soiled, wipe it off and newly lubricate the parts.

Note:

See the “mechanism assembly” diagram of the “parts list”

•

for the lubricating or greasing spots, and for the types of oil or grease to be used.

1.7.3 Suggested servicing schedule for main components

The following table indicates the suggested period for such service measures as cleaning, lubrication and replacement. In practice, the indicated periods will vary widely according to environmental and usage conditions. However, the indicated components should be inspected when a set is brought for service and the maintenance work performed if necessary.

DISASSEMBLING/ASSEMBLING OF MECHANISM

1. Before disassembling/assembling

1.1 Notes

This model’s mechanism relates closely to the rotary encoder and system control circuit (the rotary encoder is meshed with the control cam). The system circuit detects the mechanism condition using the rotary encoder’s phase (internal switch phase). Therefore, the parts such as the rotary encoder, control plate, locking gear and control cam need to be installed correctly in order for the mechanism to operate properly. (For the mechanism phase adjustment, refer to the installation of each part.)

• For the disassembling procedure of the main parts of the main unit and notes, refer to the “Specific items for the product”.

• Before using a soldering iron, be sure to disconnect the power plug from the AC outlet.

• Do not touch any of the adjustment points until a defect position is specified.

• When plugging or unplugging the connector, be sure not to damage the wire.

• Be sure the springs are hooked all the way around and in the correct direction.

• When performing repairs, take care not to damage a catch, etc.

1.3 Setting the mechanism assembling mode

The mechanism-assembling mode is provided with this mechanism. When disassembling and assembling, it is required to engage this mode. Set the mode by adopting the following procedures. (1) Remove the mechanism assembly using the disassembling

procedure.

(2) Turn gear (a) of the loading motor manually to set the mecha-

nism assembly to the eject end mode. Make sure that the main deck is connected to the guide hole (a) of the drive lever and the seal (a) of the main deck is connected to the mark “E” of the control plate. This condition is called the mechanism-assembling mode.

3.2 Mechanism compatibility adjustment Notes:

• Although compatibility adjustment is very important, it is not necessary to perform this as part of the normal servicing work. It will be required when you have replaced the A/C head, drum assembly or any part of the tape transport system.

• To prevent damaging the alignment tape in the compatibility adjustment, prepare a cassette tape (for self-recording/playback), perform a test on it by transporting it and making sure that the tape is not bent by the tape transport mechanisms such as in the guide rollers.(See Fig.3-2-2a)

(1) Play back the alignment tape (A1). (2) Apply the external trigger signal to D.FF (E), to observe

the V.PB FM waveform at the measuring point (D). (3) Set the VCR to the manual tracking mode. (4)

Make sure that there is no significant level drop of the V.PB

FM waveform caused by the tracking operation, with its

generally parallel and linear variation ensured. Perform the

following adjustments when required. (See Fig. 3-2-2b.) (5) Reduce the V.PB FM waveform by the tracking opera-

tion. If a drop in level is found on the left side, turn the

guide roller of the pole base assembly (supply side) with

the roller driver to make the V.PB FM waveform linear.

If a drop in level is on the right side, likewise turn the guide

roller of the pole base assembly (take-up side) with the

roller driver to make it linear. (See Fig. 3-2-2b.) (6) Make sure that the V.PB FM waveform varies in parallel

and linearly with the tracking operation again. When re-

quired, perform fine-adjustment of the guide roller of the

pole base assembly (supply or take-up side). (7) Unload the cassette tape once, play back the alignment

tape (A1) again and confirm the V.PB FM waveform. (8)

After adjustment, confirm that the tape wrinkling does not

occur at the roller upper or lower limits. (See Fig. 3-2-2a.)

• Maximum waveform

(1) Play back the alignment tape (A). (2) Apply the external trigger signal to D.FF (E), to observe

the AUDIO OUT waveform and Control pulse waveform

at the measuring points (D1) and (D2) in the ALT mode. (3) Set the VCR to the manual tracking mode. (4) Adjust the AUDIO OUT waveform and Control pulse

waveform by turning the screws (1), (2) and (3) little by

little until both waveforms reach maximum. The screw (1)

and (3) are for adjustment of tilt and the screw (2) for azi-

muth.

the V.PB FM waveform at the measuring point (D). (3) Set the VCR to the manual tracking mode. (4) Loosen the screws (4) and (5), then set the Roller driver

to the innermost projected part of the A/C head. (See Fig.

3-2-4a.) (5) Rotate the roller driver so that the A/C head comes clos-

est to the capstan. From there, move the A/C head back

gradually toward the drum until the point where the FM

waveform is maximized for the second time, and then

tighten the screws (4) and (5) temporarily. (6) Play an alignment tape (A2) and set to the manual-track-

ing mode. (7) Fine-adjust A/C head base position to maximize the FM

waveform, and then tighten the screws (4) and (5) firmly. (8) Play alignment tapes (A1) and (A2) and confirm that the

FM waveforms are maximized when the tracking is at the

center position.

3.3 Electrical Adjustment

Note:

The following adjustment procedures are not only necessary after replacement of consumable mechanical parts or board assemblies, but are also provided as references to be referred to when servicing the electrical circuitry. In case of trouble with the electrical circuitry, always begin a service by identifying the defective points by using the measuring instruments as described in the following electrical adjustment procedures. After this, proceed to the repair, replacement and/or adjustment. If the required measuring instruments are not available in the field, do not change the adjustment parts (variable resistor, etc.) carelessly.
