SECTION 1
PRECAUTION
1.1 SAFTY PRECAUTIONS
Prior to shipment from the factory, JVC products are strictly in-
spected to conform with the recognized product safety and elec-
trical 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 spu-
rious radiation emission.
(3) Fuse replacement caution notice.
Caution for continued protection against fire hazard.
Replace only with same type and rated fuse(s) as speci-
fied.
(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.
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.
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 volt-
age circuits, and related circuits are specified for compli-
ance 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 cir-
cuits.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 be-
tween the power cord and power trans former primary lead
wires are performed using crimp type connectors, if replac-
ing the connectors is unavoidable, in order to prevent safe-
ty 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 re-
use a connector (discard it).
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.
Fig.1-1-4
c) Align the lengths of the wires to be connected. In-
sert the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, use the crimping tool to
crimp the metal sleeve at the center position. Be
sure to crimp fully to the complete closure of the
tool.

1.1.2 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 compli-
ance with safety standards.
(1) Insulation resistance test
Confirm the specified insulation resistance or greater be-
tween power cord plug prongs and externally exposed
parts of the set (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone 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 Fig.1-1-11 below.
(3) Clearance distance
When replacing primary circuit components, confirm spec-
ified clearance distance (d), (d') between soldered termi-
nals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 below.
Fig.1-1-8
(4) Leakage current test
Confirm specified or lower leakage current between earth
ground/power cord plug prongs and externally exposed ac-
cessible parts (RF terminals, antenna terminals, video and
audio input and output terminals, microphone jacks, ear-
phone jacks, etc.).
Measuring Method : (Power ON)Insert load Z between
earth ground/power cord plug prongs and externally ex-
posed accessible parts. Use an AC voltmeter to measure
across both terminals of load Z. See Fig.1-1-9 and follow-
ing Fig.1-1-12.
Fig.1-1-9
(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 Fig.1-1-10 and grounding
specifications.

SPECIFIC SERVICE INSTRUCTIONS
2.1 Different table of features
The following table indicates main different points between models DR-MV5BEK and DR-MV5SEK.
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, DVD unit, switching
regulator, digital, 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 assem-
blies. 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 inop-
erative status.
•In order to diagnose the playback or recording of the
cassette tape, set the Mechanism assembly to the re-
quired mode before placing it upside down. If the mech-
anism mode is changed (including ejection) while it is in
an upside down position the tape inside may be dam-
aged.
•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 dis-
connected.

2.3 Jig RCU mode
This unit uses the following two modes for receiving remote con-
trol 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 EE-
PROM, 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 neces-
sary 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, "Re-
mote 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.

ery 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 unit 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.

symbols ("TIMER" or "HDD") in the FDP (LED) are turned
on.
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, re-
sulting 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.

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 ser-
vice measures as cleaning, lubrication and replacement. In prac-
tice, 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 ser-
vice and the maintenance work performed if necessary. Also
note that rubber parts may deform in time, even if the set is not
used.

4.2 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 re-
placed the A/C head, drum assembly or any part of the
tape transport system.
•To prevent damaging the alignment tape in the compat-
ibility adjustment, prepare a cassette tape (for self-re-
cording/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.4-2b.)
4.2.1 Tension pole position
Notes:
•This adjustment must be performed every time the ten-
sion band is replaced.
(1) Play back the back tension cassette gauge (A).
(2) Check that the indicated value on the left side gauge is
within the specified value (G).
(3) If the indicated value is not within the specified value (G),
perform the adjustment in a following procedure.(See
Fig.4-2a.)
a) Remove the top frame, cassette holder and side
frames (L/R) all together. (Refer to the SERVICE
MANUAL No.86700 [MECHANISM ASSEMBLY].)
b) Rotate the loading motor gear to move the control
plate so that the triangular stamping to the left of the
“P”stamping is aligned with the stamping (a) on the
main deck. This positioning is mode (B1).
c) Adjust by turning the adjustment pin so that the tip of
the tension arm is aligned with the stamping (b) on
the main deck.
d) Rotate the reel disk (S) by about one turn clockwise
and make sure that the round hole of the adjustment
pin is located in the “OK” range. If it is outside this
range, restart the adjustment from the beginning.
After completion of the adjustment, rotate the loading gear
motor to return it to the mode (B2) position.
Fig.4-2a
4.2.2 FM waveform linearity
(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. 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.)
[Perform adjustment step (9) only for the models equipped
with SP mode and EP (or LP) mode.]

5.3.4 EMG content description
Note:
EMG contents “E09” are for the model with Dynamic Drum (DD).
If the mechanism mode does not change to the next mode within 4 sec-
onds 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 sec-
onds 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 gen-
erated 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 mecha-
nism 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 sec-
onds in the drum rotating mode, [E:04] is identified, the pinch roll-
ers 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 ejec-
tion 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 pulling-
in 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 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 gen-
erated 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.
1. The mechanism is locked in the middle of the mode transition during a tape loading operation.
2.
The mechanism overruns during the tape loading operation because the SYSCON cannot recognize
the mechanism mode normally. This problem is due to a cause such as a rotary encoder failure.
3. Power is not supplied to the loading MDA. (M12V/Vcc/Vref/ICP are disconnected in the middle.)
1. The mechanism is locked in the middle of mode transition.
2. 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)
3. Power is not supplied to the loading MDA. (M12V/Vcc/Vref/ICP are disconnected in the middle.)
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 because the mechanism mal-functions for
some reason.
2) 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.
2. 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.
3. Power(SW5V) is not supplied to the reel sensor on the tape winding side.
1. 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.
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 (M12V) is not supplied to the drum MDA.
1. The cassette cannot be ejected due to a failure in the drive mechanism of the housing.
2. 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.
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 (M12V) is not supplied 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 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 (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 (M12V, SW5V) are 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 DVD unit is defective.
2. Contact failure of the wires in the DVD unit or VHS side.
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.
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 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.
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 take up 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.
3. The power (SW 5V) 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 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.

5.3.6 EMG detail information <2>
The type of the cassette tape and the cassette tape winding po-
sition can be confirmed based on the figure in EMG detail infor-
mation <2> .
Note:
•EMG detail information <2> is the reference information
stored using the remaining tape detection function of
the cassette tape. As a result, it may not identify cas-
sette correctly when a special cassette tape is used or
when the tape has variable thickness.
*5 : Cassette tape type <1>
Notes:
•Cassette tape type <1> is identified a few times during
mode transition and the identification count is variable
depending on the cassette tape type. If an EMG occurs
in the middle of identification, the cassette tape type
may not be able to be identified.
•If other value than those listed in the above table is dis-
played, the cassette tape type is not identified.
*6 : Cassette tape winding position
The cassette tape winding position at the moment of EMG is dis-
played by dividing the entire tape (from the beginning to the end)
in 21 sections using a hex number from “00” to “14”.
*7 : Cassette tape type <2> (Winding area)
Note:
•The values of cassette tape type <2> in the above table
are typical values with representative cassette tapes.
5.3.7 EMG detail information <3>
Three deck operation modes preceding the deck operation mode
in which the EMG occurs may be confirmed based on the figures
