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 Hard Disk Drive (HDD) Handling Precautions
The HDD is a precision device for use in reading and writing a large amount of data on or from a disk rotating at a high speed. If it is
not handled carefully, either abnormal operation may result or it may not be possible to read data. The HDD is sensitive to the following
items and special care is required in safeguarding against them when handling an HDD. Also take care in handling a set incorporating
an HDD.
(1) Vibrations and impacts
(2) Static electricity
(3) Rough handling
1.2.1 Handling in transport, etc.
• Be sure to place the HDD in the manufacturer's specified package carton before transport.
• When receiving a package containing an HDD, check that the
package carton is not damaged (such as having holes in the
carton, crushed corners, etc.).
• Do not impact the packaging carton when loading or unloading
HDD
Do not throw or
drop packages.
it.
• It is not permitted to use the inner package carton only for
transporting an HDD.
• Do not stack package cartons one upon another.
Be sure to package and
transport the HDDs correctly.
1.2.2 Handling an HDD in the stand-alone status
• When handling an HDD on a hard workbench, place an antistatic mat (rubber sheet) or similar object on the hard surface
(to prevent any impacts occurring between the HDD and
bench).
• Do not stack the HDDs one upon another.
• Do not knock an HDD with a hard object (such as a screwdriver).
• Do not place an HDD on its side panel without using a support
(do not place an HDD in an unstable position).
1.2.3 Handling the installation of an HDD
• Place antistatic mats or similar sheets on all of the surfaces on which work is conducted or when the HDD is transported.
• Do not permit the HDD to knock against the set's brackets.
• When screwing the brackets, be careful not to knock the HDD. When using a power screwdriver, use a low-shock model and arrange
the tightening torque properly.
• When mounting an HDD in a main body, take care not to apply excessive force to the brackets.

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, HDD, DVD unit,
switching regulator, digital, DV jack, junction and Main
board assemblies.
(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 unit 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 unit 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:
• When the unit is set to Jig RCU mode and when the unit
is under Jig RCU mode, the remote control unit attached
to product operates only in "Remote Control Code 1".
Since the unit is in "Remote Control Code 3" when it is
shipped and just after its batteries are changed, "Remote Control Code 3" needs to be changed to "Remote
Control Code 1."
• Confirm the RCU mode when exchanged parts. Since
some SERVICE PARTS sets the unit to the Jig RCU
mode as initial setting. Therefore please set the unit to
the user RCU mode after replacing the EEPROM.

4.2 Disassembly/assembly of the mechanism assembly
4.2.1 Introduction
The disassembly and assembly of the mechanism assembly should usually be performed in the ASSEMBLY mode.(Table 4-2-1)
Note that the mechanism is in the cassette in (C-IN) mode when the mechanism assembly is taken out of the set and that the C-IN
mode should be switched to the ASSEMBLY mode in this case.
To set the ASSEMBLY mode, apply 3 V DC to the electrodes on the upper part of the loading motor as shown in Fig. 4-2-7.

4.2.2 Mechanism modes
The mechanism has 6 modes as shown in Table 4-3-1. The current mode can be confirmed by the positioning of the " " marking on
the sub-cam gear and the " " marking on the mechanism. See the following figures (Figs. 4-2-1 to -6) for details.
Note:
• This mechanism assembly has another ASSEMBLY mode. However, this mode cannot be identified from the markings because
it corresponds to an intermediate position between the C-IN ( C ) mode and S-FF ( H ) mode. This mode can be confirmed by the
rotary encoder phase. See Fig. 4-2-7.

4.10.3 Linearity adjustment
The following flowchart shows the linearity check/adjustment
procedure.
4.10.4 PB switching point adjustment
The following flowchart shows the PB switching point adjustment
procedure.
Connect an oscilloscope (CH: + Slope) and, while
triggering it with the HID signal, observe the ENV OUT
Play the alignment tape, then set “ATF” (Auto Tracking
Find) in “Deck Controller” of the SSS Software to ON.
(Note 3)
Ensure that the ENV OUT waveform is linear and parallel,
without a noticeable drop or variation in the overall level. If
the waveform linearity is poor or there is a noticeable drop
in level, adjust the guide roller by turning it with the roller
driver.
Set “ATF” (Auto Tracking Find) to OFF using “Deck
Controller” of the SSS Software (Note 4). Observe the ENV
OUT waveform to confirm that the overall waveform
balance and linearity levels vary in accordance with the
tracking variation as shown in Fig. 4-10-4.
Repeat above steps
as required.
No
Is the PB ENV waveform ideally
stable and does it vary ideally
according to the tracking variation?
Load the alignment tape.
The “PB Switching Point” in the Adjustment Utility of
the SSS software is adjusted automatically.
4.10.5 Error rate adjustment
The following flowchart shows the error rate adjustment procedure.
Record for about 5 minutes. (Note 6)
While playing the recorded signal, adjust “

Fig.4-10-4
Note 3 :
• If ATF is turned off, the DV section performs tracking only of
the speed system. Therefore, as time passes, the servo will
be lost and the linearity adjustment will become difficult.
Note 4 :
• Since the speed servo function is active when ATF is off,
there will be no problem even if the DVC ATF function is off,
provided that it is for a few minutes.
Yes
The error rate adjustment is complete when the minimum
error rate which is no higher than the typical value is
obtained. (Note 5)
Note 5 :
• The "typical value" refers to the following:CH1 or CH2: < 498
; with Viterbi OFF. Inter-channel difference: < 10 times between CH1 and CH2.
Note 6 :
• It is desirable to use a brand-new tape or an unused section
of tape. This is to assure the adjustment reliability because
using a damaged tape increases the error rate.
4.10.6 Error rate measuring method
It is not necessary to use the error rate jig (YTU93083) or a frequency counter. The Service Support System Software displays
the error rates of video CH1, CH2 and totals. When measuring
the error rate of a channel, be sure to total the values of the video
and the audio errors.

4.11 Electrical adjustment (DV SECTION)
4.11.1 Precautions
(1) The DV section of this model is based on a special adjust-
ment method using a PC. However, ordinary adjustment is
required only when the part listed below has been replaced. In this case, the adjustment should be performed
by a service center equipped with the required facilities.
• E2 PROM (IC1504 on DV main board)
In case of trouble with the electrical circuitry, First identify
the faulty position with a measuring tool as described below. Proceed to repair, replacement and/or adjustment only
after the troubleshooting.
(2) When observing a chip TP, use an IC clip or similar tool to
protect the chip against stress. When replacing a chip part
(IC, particularly), remove solder completely before replacing. (This is to prevent separation of the pattern.)
(3) The connectors are fragile. Be careful when plugging or un-
plugging a wire.
4.11.2 Equipment required for adjustment
• Personal computer (Windows compatible)
• Color monitor
• Oscilloscope (2-CH, 100 MHz or more)
• Frequency counter
4.11.4 Setup
1. Setup for computer adjustment
- Setup by extending the jig connector -
-Setup by extending the jig connector-
Connect the Jig Connector Cable and setup the SSS software. It
automatically becomes the TCCS mode and "TCCS" is displayed on
the FDP.
To cancel the TCCS mode, press the CANCEL button of the remote

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.

TROUBLESHOOTING
5.1 Manually removing the cassette tape
If a loaded cassette tape cannot be ejected due to a failure in the
electrical circuitry, take the cassette tape out using the following
procedure. However, this method consists of a forced driving of
the loading motor. Therefore, the following description assumes
that there is no trouble in the mechanism operations.
(1) Unplug the power plug from the power outlet, then remove
the top cover.
(2) Apply 3 V DC to the electrodes (Red wire: + pole. Brown
wire: - pole) on the upper part of the loading motor to perform the unloading operation so that the pole base assemblies are returned on the inner side of the tape. At this time,
the exit guide arm assembly should return toward the drum
assembly and the mechanism should enter the C-IN mode.
As the tape is left without winding, be careful not to damage
the tape or leave grease on it.

DC 3 V
+
Motor bracket assembly (Loading motor)
(3) If the tape is slack, wind it up by turning the shaft on the top-
side of the capstan motor in the direction of the arrow using
a pointed tool (chip IC replacement jig).This operation may
be difficult because the shaft is located below the housing
motor of the cassette housing assembly. Be careful not to
damage parts during it.
(4) After confirming that the tape is fully wound up, take out the
cassette tape by turning the gear of the cassette housing
assembly in the direction of the arrow.
Note :
• After ejecting the tape, check that grease or similar foreign
material is not attached to the wound tape. Also perform similar checking for the mechanism assembly, particularly the
tape transport system.

5.4.7 Booting the system using the CD
The firmware of this device is stored in the Hard Disk Drive (HDD). If the firmware is collapsed for its contents, [LOADING] is repeatedly
displayed on the FDP display of the main unit and the system becomes inoperative. The system operation cannot be resumed even
if the AC plug is disconnected from the AC power source.
In such a situation, the operation may be resumed on a temporary basis to normal using a CD that stores the firmware. This causes
the firmware in the HDD to be updated and the system may be brought to a normal operation. Refer to the following descriptions for
detail.
5.4.7.1 Downloading the firmware from JS-NET to create a booting disk
NOTE:
For details of creating the booting disk, see the instructions provided in the JS-NET web site.
(1) Download all the relevant files from the JS-NET and decompress it.
(2) The file termed "bootup1.blx" will accordingly be created. Copy this file in a root directory of the CD-R.
(3) Set the track setting to [MODE2 XA] for writing the software, and select [JOLIET] as an exchangeable file name. Be sure to write
the disk in [Disk at once] mode.
5.4.7.2 Booting using the Disk
The following explanation is made assuming the system operation is being unable with [LOADING] repeatedly displayed.
(1) Disconnect the AC plug and then connect it again. Immediately after this, press and hold the DVD ON/OFF button until the tray
comes out.
(2) Put the booting disk on the tray and close the tray.
(3) Disconnect the AC plug. Press and hold the STOP button and connect the AC plug.
(4) Keep the button pressed for 20 seconds and release the button (Timing must be precise).
(5) [LOADING] will be displayed repeatedly for a while and the system will be brought to the standby state.
(6) Press the OPEN/CLOSE button to remove the booting disk.
(7) Turn the system on and confirm that the operation is normal. If so, the system should be properly booted from the CD-R.
5.4.7.3 Updating the firmware after booting with the CD
By updating the firmware using the CD, the built-in firmware in the HDD will be overwritten, allowing the firmware to be renovated. The
system may be resumed to a normal state using this method. Be sure to download the latest version of the update firmware when you
attempt to create and use the firmware. For the updating procedures, refer to 5.4.2.
