1-2 (No.YD001)
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.
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.
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

NOTE :
These tables are unofficial and for reference only. Be sure to confirm the precise values for your particular country and locality.
1-4 (No.YD001)
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.
1.2.1Grounding 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.YD001)1-5
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), short-circuit the flexible wire by the metal clip.
(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.

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 disassembly of the major parts before removing the Mechanism assembly.
(2)Remove the screws that fix the Mechanism, Regulator board assembly to the bottom chassis. If any other screws are used to fix the boards, remove them also.
(3)Remove the combined Mechanism,Regulator borad 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 assembly.
Notes:
•Before inserting the power cord plug into the power outlet, 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.
(No.YD001)1-7
•For some models, the mechanism and board assemblies 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.

2.3Jig 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 MENU " → " 2 " → " 8 " → " OK ". 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)
1-8 (No.YD001)
2.3.2 Setting the User RCU mode
(1)Turn off the power.
(2)Press the "REC" and "PAUSE" buttons of the VCR simultaneously. Alternatively, transmit the code "80" from the Jig RCU.
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 "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.
Either of the two different kinds of Main boards is used for HRXVC30US, HR-XVC33US, HR-XVC33UC, and HR-XVC33UM, according to a period of production.Since the two types of boards have different circuits and parts numbers, check what type of board is used for the product before your analysis and repair work.The following is how to distinguish the Main board.
(1)Remove the Top cover. (See “SECTION 3 Removing the major parts”)
(2)Check whether "CN501" is printed in a space between the
Mechanism Assembly and the Rear cover. (See Figure 2- 5a.)

2.6.1 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 cotton swab soaked with alcohol.
(3)After cleaning, make sure that the cleaned parts are completely dry before using the cassette tape.

2.6.2 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.
2.6.3 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.
