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.

SPECIFIC SERVICE INSTRUCTIONS

2.1 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.
2.1.1 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, 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. 2-1a,
2-1b.) (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.

2.2 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.

2.2.1 Setting the Jig RCU mode
(1) Turn on the power. (2) Press the following remocon keys continuously within 2
seconds " MENU "
" 2 " " 8 " " OK ".
When the VCR is set to the Jig RCU mode, the symbols ( " : " ) in the time display of the FDP are blinked. (Refer to Fig.2-2a User/Jig RCU mode)
2.2.2 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.

2.3 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".
2.3.1 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.
2.3.2 How to exit from the "Mechanism service mode"
(1) Unplug the power cord plug from the power outlet.

2.4 Maintenance and inspection

2.4.1 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.
1-6 (No.YD032)
(3) After cleaning, make sure that the cleaned parts are com-
pletely dry before using the cassette tape.

Video heads
Fig.2-4a
2.4.2 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.
2.4.3 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.
