SECTION 1

PRECAUTION

1.1 SAFTY 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.

1.1.1 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 comply 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:

• Wires covered with PVC tubing

• Double insulated wires

• High voltage leads

(5) Use specified insulating materials for hazardous live parts.

Note especially:

• Insulation Tape

• PVC tubing

•Spacers

• Insulation sheets for transistors

•Barrier

(6) When replacing AC primary side components (transformers,

power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.

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.

(12) Crimp type wire connectorIn such cases as when replacing

the power transformer in sets where the connections between the power cord and power trans former 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.

• Connector part number :E03830-001

• Required tool : Connector crimping tool of the proper type which will not damage insulated parts.

• Replacement procedure

a) 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.1-1-3

b) 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.1-1-4

c) Align the lengths of the wires to be connected. In-

sert the wires fully into the connector.

Metal sleeve

Fig.1-1-1

(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.1-1-2 (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.

1.2 Preventing static electricity

Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.

1.2.1 Grounding to prevent damage by static electricity

Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players. Be careful to use proper grounding in the area where repairs are being performed.

(1) Ground the workbench

Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it.

(2) Ground yourself

Use an anti-static wrist strap to release any static electricity built up in your body.

(3) Handling the optical pickup

• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.)

• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode.

(No.YD052)1-5

1.3 Precautions for Service

1.3.1 Handling of Traverse Unit and Laser Pickup

(1) Do not touch any peripheral element of the pickup or the actuator. (2) The traverse unit and the pickup are precision devices and therefore must not be subjected to strong shock. (3) Do not use a tester to examine the laser diode. (The diode can easily be destroyed by the internal power supply of the tester.) (4) To replace the traverse unit, pull out the metal short pin for protection from charging. (5) When replacing the pickup, after mounting a new pickup, remove the solder on the short land which is provided at the center of

the flexible wire to open the circuit.

(6) Half-fixed resistors for laser power adjustment are adjusted in pairs at shipment to match the characteristics of the optical block.

Do not change the setting of these half-fixed resistors for laser power adjustment.

1.3.2 Destruction of Traverse Unit and Laser Pickup by Static Electricity

Laser diodes are easily destroyed by static electricity charged on clothingor the human body. Before repairing peripheral elements of the traverse unit or pickup, be sure to take the following electrostatic protection:

(1) Wear an antistatic wrist wrap. (2) With a conductive sheet or a steel plate on the workbench on which the traverse unit or the pick up is to be repaired, ground the

sheet or the plate. (3) It solders to two short circuit sections on the substrate of a pick-up. (4) After removing the flexible wire from the connector (CN101 (5) Short-circuit the laser diode by soldering the land which is provided at the center of the flexible wire for the pickup.

After completing the repair, remove the solder to open the circuit.

), short-circuit the flexible wire by the metal clip.

2.2 Service position

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

2.2.1 How to set the "Service position"

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

sembly of the major parts before removing the Mechanism assembly.

(2) Remove the screws that fix the Mechanism, Main board as-

sembly to the bottom chassis. 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. 2-2a.) (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 "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 assem-

blies 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.

2.3 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.

Note:

• Confirm the RCU mode when exchanged parts. Since

some SERVICE PARTS sets the VCR to the Jig RCU mode as initial setting. Therefore please set the VCR to the user RCU mode after replacing the EEPROM.

Fig.2-3a User/Jig RCU mode

2.3.1 Setting the Jig RCU mode

(1) Turn on the power. (2) Press the following remocon keys continuously within 2

seconds " SET UP " → " 2 " → " 8 " → " ENTER ".

When the VCR is set to the Jig RCU mode, the symbols ( " : " ) in the time display of the FDP are turned off. (Refer to Fig.2-3a)

2.3.2 Setting the User RCU mode

(1) Turn off the power. (2) Press the "REC" and "PAUSE" buttons of the VCR simul-

taneously. Alternatively, transmit the code "43-80" from the Jig RCU.

2.4 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".

2.4.1 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 "43-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

completed, 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.

2.4.2 How to exit from the "Mechanism service mode"

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

2.5 Maintenance and inspection

2.5.1 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 cot-

ton swab soaked with alcohol.

A/C head

Fig.2-5a

2.5.2 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.

2.5.3 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. Also note that rubber parts may deform in time, even if the set is not used.

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. 4-2c.) (5) Reduce the V.PB FM waveform by the tracking operation.

If a drop in level is found on the left side, turn the guide roll-

er 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. 4-2c.) (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. 4-2b.)

EU1: Head clog warning history

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 communication with a system computer of VHS side is not carried out because of the defective DVD unit, or when the DVD unit must be reset

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

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;

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;

2) 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.

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);

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 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.

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