Important Safety Precautions
Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codesof the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement thefollowing precautions when a set is being serviced.
Fig.1
1. Locations requiring special caution are denoted by labels andinscriptions on the cabinet, chassis and certain parts of theproduct. When performing service, be sure to read and com-ply with these and other cautionary notices appearing in theoperation and service manuals.
2. Parts identified by the symbol and shaded ( ) parts arecritical 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 usingcathode ray tubes and those specified for compliancewith various regulations regarding spurious radiationemission.
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 tubing2) Double insulated wires3) High voltage leads
5. Use specified insulating materials for hazardous live parts.Note especially:1) Insulation Tape 3) Spacers 5) Barrier2) PVC tubing 4) Insulation sheets for transistors
6. When replacing AC primary side components (transformers,power cords, noise blocking capacitors, etc.) wrap ends ofwires securely about the terminals before soldering.
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 forcompliance with recognized codes pertaining to X-ray emission.Consequently, when servicing these products, replace the cath-ode 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 valueand cause X-ray emission from the cathode ray tube.
12. Crimp type wire connectorIn such cases as when replacing the power transformer in setswhere the connections between the power cord and powertransformer primary lead wires are performed using crimp typeconnectors, if replacing the connectors is unavoidable, in or-der to prevent safety hazards, perform carefully and preciselyaccording to the following steps.
1) Connector part number : E03830-0012) 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 pointclose to the connector.Important : Do not reuse a connector (discard it).
Fig.7
cut close to connector
Fig.3
(2) Strip about 15 mm of the insulation from the ends ofthe wires. If the wires are stranded, twist the strands toavoid frayed conductors.

v Safety Check after ServicingExamine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have beenreturned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli-ance with safety standards.
1. Insulation resistance testConfirm the specified insulation resistance or greater between power cord plug prongs andexternally exposed parts of the set (RF terminals, antenna terminals, video and audio inputand output terminals, microphone jacks, earphone jacks, etc.). See table 1 below.
2. Dielectric strength testConfirm specified dielectric strength or greater between power cord plug prongs and exposedaccessible parts of the set (RF terminals, antenna terminals, video and audio input and outputterminals, microphone jacks, earphone jacks, etc.). See table 1 below.
3. Clearance distanceWhen replacing primary circuit components, confirm specified clearance distance (d), (d’) be-tween soldered terminals, and between terminals and surrounding metallic parts. See table 1below.
4. Leakage current testConfirm specified or lower leakage current between earth ground/power cord plug prongsand externally exposed accessible parts (RF terminals, antenna terminals, video and audioinput 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 accessi-ble parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 andfollowing 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.

1.4 Service position
This unit has been designed so that the Mechanism andMain board assemblies can be removed together from thechassis assembly. Before diagnosing or servicing the cir-cuit boards, take out the major parts from the chassis as-sembly.
1.4.1 How to set the “Service position”
(1) Remove the Top cover, Bracket, Front panel assemblyand Mini front board assembly. (See1.3 Disassembly/assembly method.)
(2) Lower the cassette holder to prepare for the removal ofthe Mechanism assembly screws. (Refer to the “Proce-dures for lowering the Cassette holder assembly” of 1.3Disassembly/assembly method.)
(3) Remove the combined Mechanism and Main board as-semblies.
(4) Connect the wires and connectors of the major parts thathave been removed in step (1). (Refer to Fig.1-4-1a.)
(5) Place the combined Mechanism and Main board assem-blies upside down.
(6) Insert the power cord plug into the power outlet and thenproceed with the diagnostics and servicing of the boardassembly.
Notes:• Before inserting the power cord plug into the power
outlet, make sure that none of the electrical parts areable to short-circuit between the workbench and theboard assembly.
• For the disassembly procedure of the major parts anddetails of the precautions to be taken, see “1.3 Disas-sembly/assembly method”.
• If there are wire connections from the Main board andMechanism assemblies to the other major parts, besure to remove them ( including wires connected to themajor parts ) first before performing step (2).
• When carrying out diagnosis and repair of the Mainboard assembly in the “Service position”, be sure toground both the Main board and Mechanism assem-blies. If they are improperly grounded, there may benoise on the playback picture or FDP counter displaymay move even when the mechanism is kept in an in-operative status.
• In order to diagnose the playback or recording of thecassette tape, set the Mechanism assembly to the re-quired mode before placing it upside down. If themechanism mode is changed (including ejection) whileit is in an upside down position the tape inside maybe damaged.
1.5 Mechanism service mode
This model has a unique function to enter the mechanisminto every operation mode without loading of any cassettetape. This function is called the “Mechanism service mode”.
1.5.1 How to set the “Mechanism service mode”
(1) Unplug the power cord plug from the power outlet.(2) Connect TPGND and TP7001(TEST) on the Main board
assembly with a jump wire.(3) Insert the power cord plug into the power outlet.(4) With lock levers (A) (B) on the left and right of the Cas-
sette holder assembly pulled toward the front, slide theholder in the same direction as the cassette insertion di-rection. (For the positions of lock levers (A) (B), refer tothe “Procedures for lowering the Cassette holder assem-bly” of 1.3 Disassembly/assembly method.)
(5) The cassette holder lowers and, when the loading hascompleted, the mechanism enters the desired mode.
1.6 Jig RCU mode
This unit uses the following two modes for receiving remotecontrol codes.1) User RCU mode : Ordinary mode for use by the user.2) Jig RCU mode : Mode for use in production and serv-
icing.
When using the Jig RCU, it is required to set the VCR tothe Jig RCU mode (the mode in which codes from the JigRCU can be received). As both of the above two modesare stored in the EEPROM, it is required to set the VCRback to the User RCU mode each time that an adjustmentis made or to check that the necessary operations havebeen completed. These modes can be set by the opera-tions described below.
1.6.1 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 pluginto 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.
1.6.2 Setting the User RCU mode
(1) Turn off the power.(2) Press the “REC” and “PAUSE” buttons of the VCR si-
multaneously. Alternatively, transmit the code “80” fromthe Jig RCU.

When the mechanism mode cannot be changed to an-other mode even when the loading motor has rotatedfor more than 4 seconds in the loading direction, [E:01]is identified and the power is turned off.
When the mechanism mode cannot be changed to an-other mode even when the loading motor has rotatedfor more than 4 seconds in the unloading direction, [E:02]is identified and the power is turned off.
When the take-up reel pulse has not been generated formore 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. However, the reel EMG isnot detected in STILL/SLOW modes.
When the drum FG pulse has not been input for morethan 3 seconds in the drum rotating mode, [E:04] is iden-tified, the pinch rollers are turned off and stopped, andthe power is turned off.
When the eject operation does not complete in 3 sec-onds after the start, [E:05] is identified, the pinch rollersare turned off and stopped, and the power is turned off.When the cassette insertion operation does not completein 3 seconds after the start, the cassette is ejected. Inaddition, when the operation does not complete within3 seconds after the start, [E:05] is also identified and thepower is turned off immediately.
When the capstan FG pulse has not been generated formore 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 EMGis not detected in STILL/SLOW/FF/REW modes.
When short-circuiting of the SW power supply with GNDhas 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 isturned off.
When the DD FG pulse is not generated within 2.5 sec-onds, [E:09] is identified, the tilt motor is stopped andthe power is turned off.
When the supply reel pulse has not been generated formore than 10 seconds in the capstan rotating mode,[E:0A] is identified and the cassette is ejected (but thepower is not turned off). However, note that the reel EMGis not detected in the SLOW/STILL mode.
1. The mechanism is locked in the middle of mode transition.2. The mechanism is locked at the loading end due to the encoder position
reading error during mode transition.3. Power is not supplied to the loading MDA.
1. The mechanism is locked in the middle of mode transition.2. The mechanism is locked at the unloading end due to the encoder posi-
tion reading error during mode transition.3. Power is not supplied to the loading MDA.
1. 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;2) The idler gear is meshed with the take-up reel gear, but incapable of wind-
ing due to too large mechanical load (abnormal tension);3) The take-up reel sensor does not output the FG pulse.
2. The supply reel pulse is not generated in the REV transport modes (REVSEARCH/REW, etc.) because;1) The idler gear is not meshed with the supply reel gear.2) The idler gear is meshed with the supply reel gear, but incapable of wind-
ing due to too large a mechanical load (abnormal tension);3) The supply reel sensor does not output the FG pulse.
3. Power is not supplied to the reel sensors.
1. The drum could not start or the drum rotation has stopped due to too largea 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.
2. 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.
3. The drum control voltage (DRUM CTL V) is not supplied to the MDA.4. Power is not supplied to the drum MDA.
1. The cassette cannot be ejected due to a failure in the drive mechanism ofthe housing.
2. When the housing load increases during ejection, the loading motor isstopped because of lack of headroom in its drive torque.
Housing load increasing factors: Temperature environment (low tempera-ture, etc.), mechanism wear or failure.
3. The sensor/switch for detecting the end of ejection are not functioning normally.4. The loading motor drive voltage is lower than specified or power is not sup-
plied to the motor (MDA).5. 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.
1. The capstan could not start or the capstan rotation has stopped due to toolarge 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 (occurrence of tape entangling, etc.).2. 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.
3. The capstan control voltage (CAPSTAN CTL V) is not supplied to the MDA.4. Power is not supplied to the capstan MDA.
1. The SW 5 V power supply circuit is shorted with GND.2. 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.4. 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 to the sensor is not supplied. (Connection failure/soldering failure)5. The FG pulse is not sent to the System Controller CPU.6. 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.
1. 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 cas-
sette 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 rotateuntil the tape slack is removed by the FWD transport, so the pulse is notgenerated until then;
3) The FG pulse output from the supply reel sensor is absent.2. 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 rotateuntil the tape slack is removed by the REV transport, so the pulse willnot be generated until that time;
3) The FG pulse output from the take-up reel sensor is absent.3. The power to a reel sensor is not supplied.
FDP CONTENT CAUSE
Presupposing the presence of the control pulse output in the PLAY mode, when the value obtained by mixing the two V.FM outputchannels (without regard to the A.FM output) has remained below a certain threshold level for more than 10 seconds, [E:C1] or [E:U1]is identified and recorded in the emergency history. During the period in which a head clog is detected, the FDP and OSD repeat the“3-second warning display” and “7-second 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 ischanged to another mode than PLAY.

SECTION 2MECHANISM ADJUSTMENT
2.1 Before starting repair and adjustment
2.1.1 Precautions
(1) Unplug the power cord plug of the VCR before using yoursoldering iron.
(2) Take care not to cause any damage to the conductorwires when plugging and unplugging the connectors.
(3) Do not randomly handle the parts without identifyingwhere the trouble is.
(4) Exercise enough care not to damage the lugs, etc. dur-ing the repair work.
(5) When reattaching the front panel assembly, make surethat the door opener of the cassette holder assembly islowered in position prior to the reinstallation. (See SEC-TION 1 DISASSEMBLY.)
(6) When using the Jig RCU, it is required to set the VCR tothe Jig RCU mode (the mode in which codes from theJig RCU can be received). (See SECTION 1 DISASSEM-BLY.)
2.1.2 Checking for proper mechanical operations
Enter the mechanism service mode when you want to oper-ate the mechanism when no cassette is loaded. (See SEC-TION 1 DISASSEMBLY.)
2.1.3 Manually removing the cassette tape
1. In case of electrical failuresIf you cannot remove the cassette tape which is loaded be-cause of any electrical failure, manually remove it by takingthe following steps.
(1) Unplug the power cord plug from the power outlet.(2) Refer to the disassembly procedure and perform the dis-
assembly of the major parts before removing the drumassembly.
(3) Unload the pole base assembly by manually turning theloading motor of the mechanism assembly toward thefront. In doing so, hold the tape by the hand to keep theslack away from any grease. (See Fig.2-1-3a.)
(4) Bring the pole base assembly to a pause when it reachesthe position where it is hidden behind the cassette tape.
(5) Move the top guide toward the drum while holding downthe lug (A) of the bracket retaining the top guide. Like-wise hold part (B) down and remove the top guide.Section (C) of the top guide is then brought under thecassette lid. Then remove the top guide by pressing thewhole cassette tape down. (See Fig.2-1-3b.)
(6) Remove the cassette tape by holding both the slackenedtape and the cassette lid.
(7) Take up the slack of the tape into the cassette. This com-pletes removal of the cassette tape.
Note:• For the disassembly procedure of the major parts and
details of the precautions to be taken, see “SECTION1 DISASSEMBLY”.

2. In case of mechanical failureIf you cannot remove the cassette tape which is loaded be-cause of any mechanical failure, manually remove it by tak-ing the following steps.(1) Unplug the power cable and remove the top cover, front
panel assembly and others so that the mechanism as-sembly is visible. (See SECTION 1 DASASSEMBLY.)
(2) While keeping the tension arm assembly of the mecha-nism assembly free from tension, pull the tape on the polebase assembly (supply or take-up side) out of the guideroller. (See Fig.2-1-3c.)
(3) Take the spring of the pinch roller arm assembly off thehook of the press lever assembly, and detach it from thetape. (See Fig.2-1-3d.)
(4) In the same way as in the electrical failure instructions in2.1.3-1(5), remove the top guide.
(5) Raise the cassette tape cover. By keeping it in that posi-tion, draw out the cassette tape case from the cassetteholder and take out the tape.
(6) By hanging the pinch roller arm assembly spring backon the hook, take up the slack of the tape into the cas-sette.

1. Location of major mechanical partsIn this chapter, the two mechanism speeds are described by comparing the speeds of the standard type and the high-speedFF/REW type.It is possible to distinguish between these two types of mechanism by the diameters of their capstan pulleys.The capstan pulley diameter for the standard type is approx. 32 mm.The capstan pulley diameter for the high-speed FF/REW type is approx. 43 mm.For information on the different parts used in the two mechanism types, please refer to the “Replacement of major parts”.

5. Disassembling procedure tableThe following table indicates the order in which parts are re-moved for replacement. To replace parts, remove them inthe order of 1 to 18 as shown in the table. To install them,reverse the removal sequence.The symbols and numbers preceding the individual partnames represent the numbers in the “Location of major me-chanical parts” table. Also, the “T”, “B”, and “T/B” on the rightof each part name shows that the particular part is removedfrom the front, from the back, and from both sides of themechanism, respectively.
2. CleaningRegular cleaning of the transport system parts is desirablebut practically impossible. So make it a rule to carry out clean-ing of the tape transport system whenever the machine isserviced.When the video head, tape guide and/or brush get soiled,the playback picture may appear inferior or at worst disap-pear, resulting in possible tape damage.
(1) When cleaning the upper drum (especially the videohead), soak a piece of closely woven cloth or Kimu-wipewith alcohol and while holding the cloth onto the upperdrum by the fingers, turn the upper drumcounterclockwise.
Note:• Absolutely avoid sweeping the upper drum vertically
as this will cause damage to the video head.
(2) To clean the parts of the tape transport system other thanthe upper drum, use a piece of closely woven cloth or acotton swab soaked with alcohol.
(3) After cleaning, make sure that the cleaned parts are com-pletely dry before using the video tape.
3. LubricationWith no need for periodical lubrication, you have only to lu-bricate new parts after replacement. If any oil or grease oncontact parts is soiled, wipe it off and newly lubricate theparts.
Note:• See the “mechanism assembly” diagram of the parts
list for the lubricating or greasing spots, and for thetypes of oil or grease to be used.

4. Suggested servicing schedule for main componentsThe following table indicates the suggested period for suchservice measures as cleaning,lubrication and replacement.In practice, the indicated periods will vary widely accordingto environmental and usage conditions.However, the indi-cated components should be inspected when a set is broughtfor service and the maintenance work performed if neces-sary. Also note that rubber parts may deform in time,even ifthe set is not used.

2.2 Replacement of major parts
2.2.1 Before starting disassembling (Phase matchingbetween mechanical parts)
The mechanism of this unit is closely linked with the rotaryencoder and system controller circuits.Since the system controller detects the status of mechani-cal operation in response to phases of the rotary encoder(internal switch positions), the mechanism may not operateproperly unless such parts as the rotary encoder, controlplate, loading arm gear, control cam, cassette gear, limit gear,relay gear and drive gear are installed in their correct posi-tions.Especially, this model is not provided with any cassette hous-ing assembly, so that cassette loading and unloading mustbe accomplished by operation of the cassette holder assem-bly. The latter is in turn driven by such parts as the drivegear, relay gear and limit gear. Exercise enough care, there-fore, to have the phases of all this gear matching one an-other. (For information on phase matching of the mechanism,see the instructions on how to install individual parts.)This unit is provided with a mechanism assembly mode. It istherefore necessary to enter this mode for assembling anddisassembling procedures.This mode is usually not in use, manually set it when it isrequired.
2.2.2 How to set the “Mechanism assembling mode”
Remove the mechanism assembly and place it bottom sideup. (See SECTION 1 DISASSEMBLY.) Turn the worm geartoward the front so that the guide hole of the control cam isbrought into alignment with the hole at the mechanism as-sembly chassis. This position renders the mechanism assem-bling mode operational. Make sure that the control plate islocated in alignment with the mark E. (See Fig.2-2-2a.)

2.3 Compatibility adjustment
Notes:• Although compatibility adjustment is very important,
it is not necessary to perform this as part of the nor-mal servicing work. It will be required when you havereplaced the A/C head, drum assembly or any part ofthe tape transport system.
• To avoid any damage to the alignment tape while per-forming the compatibility adjustment, get a separatecassette tape (for recording and play back) ready tobe used for checking the initial tape running behavior.
• Unless otherwise specified, all measuring points andadjustment parts are located on the Main board.
• When using the Jig RCU, it is required to set the VCRto the Jig RCU mode (the mode in which codes fromthe Jig RCU can be received). (See SECTION 1 DISAS-SEMBLY.)
(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, withits generally parallel and linear variation ensured. Per-form the following adjustments when required. (See Fig.2-3-1a.)
(5) Reduce the V.PB FM waveform by the tracking opera-tion. If a drop in level is found on the left side, turn theguide roller of the pole base assembly (supply side) withthe roller driver to make the V.PB FM waveform linear.If a drop in level is on the right side, likewise turn the guideroller of the pole base assembly (take-up side) with theroller driver to make it linear. (See Fig. 2-3-1c.)
(6) Make sure that the V.PB FM waveform varies in paralleland linearly with the tracking operation again. When re-quired, perform fine-adjustment of the guide roller of the
2.3.1 FM waveform linearity

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. 2-3-1d.)
[Perform adjustment step (9) only for the modelsequipped with SP mode and EP (or LP) mode.]
