Important Safety Precautions

cut close to connector

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.

v

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 critical 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 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:

1) Wires covered with PVC tubing

2) Double insulated wires

3) High voltage leads

5. Use specified insulating materials for hazardous live parts. Note especially:

1) Insulation Tape 3) Spacers 5) Barrier

2) PVC tubing 4) Insulation sheets for transistors

6. When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.

symbol and shaded ( ) parts are

12. Crimp type wire connector In such cases as when replacing the power transformer in sets where the connections between the power cord and power transformer 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.

1) Connector part number : E03830-001

2) 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 point

close to the connector. Important : Do not reuse a connector (discard it).

Fig.3

(2) 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

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.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.

Fig.4

(3) Align the lengths of the wires to be connected. Insert

the wires fully into the connector.

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 compliance with safety standards.

1. Insulation resistance test

Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone 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 table 1 below.

3. Clearance distance

When replacing primary circuit components, confirm specified clearance distance (d), (d’) between soldered terminals, and between terminals and surrounding metallic parts. See table 1 below.

Fig. 8

4. Leakage current test

Confirm specified or lower leakage current between earth ground/power cord plug prongs and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input 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 accessible parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 and following table 2.

1.9 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.

1.9.1 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 plug into 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.

1.9.2 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 “80” from the Jig RCU.

1.10 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”.

1.10.1 How to set the "MECHANISM SERVICE MODE"

(1) Disconnect VCR from AC. (2) Connect TPGND and TP7001 (TEST) on the Display

board assembly with a jump wire. (3) Connect VCR to AC. (4) Press the POWER button.

(5) With lock levers A B on the left and right of the Cassette

holder assembly pulled toward the front, slide the holder in the same direction as the cassette insertion direction. (For the positions of lock levers A B , refer to the “Procedures for Lowering the Cassette holder assembly” on page 1-4 of 1.5 HOW TO REMOVE THE MAJOR PARTS <VHS section>

(6) The cassette holder lowers and, when the loading has

completed, the mechanism enters the desired mode.

EC1 or EU1: Head clog warning

When the mechanism mode cannot be changed to another mode even when the loading motor has rotated for 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 another mode even when the loading motor has rotated for 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 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. However, the reel EMG is not detected in STILL/SLOW modes.

When the drum FG pulse has not been input for more than 3 seconds in the drum rotating mode, [E:04] is identified, the pinch rollers are turned off and stopped, and the power is turned off.

When the eject operation does not complete in 3 seconds after the start, [E:05] is identified, the pinch rollers are turned off and stopped, and the power is turned off. When the cassette insertion operation does not complete in 3 seconds after the start, the cassette is ejected. In addition, when the operation does not complete within 3 seconds after the start, [E:05] is also identified and the power is turned 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 STILL/SLOW/FF/REW modes.

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 DD tilting does not complete in 4 seconds, [E:08] is identified, the tilt motor is 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 supply reel pulse has not been generated 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). However, note that the reel EMG is not detected in the SLOW/STILL mode.

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: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 is changed to another mode than PLAY.

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 winding 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 (REV SEARCH/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 winding 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 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.

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 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.).

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 rotate until the tape slack is removed by the FWD transport, so the pulse is not generated 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 rotate until the tape slack is removed by the REV transport, so the pulse will not 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.

SECTION 2 MECHANISM ADJUSTMENT (VHS)

2.1 Before starting repair and adjustment

2.1.1 Precautions

(1) Unplug the power cord plug of the VCR before using your

soldering iron.

(2) Take care not to cause any damage to the conductor

wires when plugging and unplugging the connectors.

(3) Do not randomly handle the parts without identifying

where 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 sure

that the door opener of the cassette holder assembly is lowered in position prior to the reinstallation. (See SECTION 1 DISASSEMBLY.)

(6) 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). (See SECTION 1 DISASSEMBLY.)

Loading motor

2.1.2 Checking for proper mechanical operations

Enter the mechanism service mode when you want to operate the mechanism when no cassette is loaded. (See SECTION 1 DISASSEMBLY.)

2.1.3 Manually removing the cassette tape

1. In case of electrical failures

If you cannot remove the cassette tape which is loaded because of any electrical failure, manually remove it by taking the 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 drum assembly.

(3) Unload the pole base assembly by manually turning the

loading motor of the mechanism assembly toward the front. In doing so, hold the tape by the hand to keep the slack away from any grease. (See Fig.2-1-3a.)

(4) Bring the pole base assembly to a pause when it reaches

the position where it is hidden behind the cassette tape.

(5) Move the top guide toward the drum while holding down

the lug (A) of the bracket retaining the top guide. Likewise hold part (B) down and remove the top guide. Section (C) of the top guide is then brought under the cassette lid. Then remove the top guide by pressing the whole cassette tape down. (See Fig.2-1-3b.)

(6) Remove the cassette tape by holding both the slackened

tape 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 “SECTION 1 DISASSEMBLY”.

2. In case of mechanical failure

If you cannot remove the cassette tape which is loaded because of any mechanical failure, manually remove it by taking the following steps.

(1) Unplug the power cable and remove the top cover, front

panel assembly and others so that the mechanism assembly is visible. (See SECTION 1 DISASSEMBLY.)

(2) While keeping the tension arm assembly of the mecha-

nism assembly free from tension, pull the tape on the pole base assembly (supply or take-up side) out of the guide roller. (See Fig.2-1-3c.)

(3) Take the spring of the pinch roller arm assembly off the

hook of the press lever assembly, and detach it from the tape. (See Fig.2-1-3d.)

(4) In the same way as in the electrical failure instructions in

2.1.3-1(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 cassette holder and take out the tape.

(6) By hanging the pinch roller arm assembly spring back

on the hook, take up the slack of the tape into the cassette.

2.1.5 Maintenance and inspection

1. Location of major mechanical parts

In this chapter, the two mechanism speeds are described by comparing the speeds of the standard type and the high-speed FF/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”.

2. 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.

(1) When cleaning the upper drum (especially the video

head), soak a piece of closely woven cloth or Kimu-wipe with alcohol and while holding the cloth onto the upper drum by the fingers, turn the upper drum counterclockwise.

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 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 com-

pletely dry before using the video tape.

3. 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.

4. 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.

2.2 Replacement of major parts

2.2.1 Before starting disassembling (Phase matching between mechanical parts)

The mechanism of this unit is closely linked with the rotary encoder and system controller circuits. Since the system controller detects the status of mechanical operation in response to phases of the rotary encoder (internal switch positions), the mechanism may not operate properly unless such parts as the rotary encoder, control plate, loading arm gear, control cam, cassette gear, limit gear, relay gear and drive gear are installed in their correct positions. Especially, this model is not provided with any cassette housing assembly, so that cassette loading and unloading must be accomplished by operation of the cassette holder assembly. The latter is in turn driven by such parts as the drive gear, relay gear and limit gear. Exercise enough care, therefore, to have the phases of all this gear matching one another. (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 is therefore necessary to enter this mode for assembling and disassembling procedures. This mode is usually not in use, manually set it when it is required.

2.2.3 Cassette holder assembly

2. How to install (Centering the mounting position)

When the capstan motor has once been removed and then reinstalled out of the initial correct position in the rotational direction, the capstan motor current may be unstable during operation in high or low temperatures. This may result in greater Wow & Flutter and occasionally in power breakdown because of current over - load. Install the capstan motor while following the procedure given below. (The capstan motor is centrally located when the unit is shipped from the factory.)

(1) Provisionally tighten the three screws (A) securing the

capstan motor.

(2) Install the mechanism assembly to which the capstan

motor is provisionally fastened on the bottom chassis which incorporates the Main board assembly. (No need to tighten the screws for mounting the mechanism.)

2.3 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 replaced the A/C head, drum assembly or any part of the tape transport system.

• To avoid any damage to the alignment tape while performing the compatibility adjustment, get a separate cassette tape (for recording and play back) ready to be used for checking the initial tape running behavior.

• Unless otherwise specified, all measuring points and adjustment parts are located on the Main board.

• 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). (See SECTION 1 DISASSEMBLY.)

(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. 2-31d.)

[Perform adjustment step (9) only for the models

equipped with SP mode and EP (or LP) mode.]

2.5 DISASSEMBLY/ASSEMBLY OF THE MECHANISM ASSEMBLY

2.5.1 Introduction

The disassembly and assembly of the mechanism assembly should usually be performed in the ASSEMBLY mode. (Table 2-5-1) 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. 2-5-

7.

2.5.2 Mechanism Modes

The mechanism has 6 modes as shown in Table 2-6-1. 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. 2-5-1 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 po-

C

sition between the C-IN (

) mode and S-FF ( H ) mode. This mode can be confirmed by the rotary encoder phase. See Fig. 2-5-7.

2.13.3 Linearity adjustment

The following flowchart shows the linearity check/adjustment procedure.

2.13.4 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 waveform.

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. 2-18-3.

Repeat above steps as required.

No

Is the PB ENV waveform ideally stable and does it vary ideally according to the tracking variation?

Yes

Load the alignment tape.

The “PB Switching Point” in the Adjustment Utility of the SSS software is adjusted automatically.

2.13.5 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 “ Frequency (ME SP) “Deck Section” of the Adjustment Utility.

Note 3 :

• The VHS section has an A/C head, and the first tracking position can be locked using the CTL pulse and drum FF when AT is off. Therefore, the linearity of the VHS section can usually be adjusted with AT off. However, this adjustment method is not available with the DV section, which does not have the A/C head. 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.

2.13.6 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.

2.14 TAPE EJECTION

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.

3. If the tape is slack, wind it up by turning the shaft on the topside 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 for-

eign material is not attached to the wound tape. Also perform similar checking for the mechanism assembly, particularly the tape transport system.

SECTION 3 ELECTRICAL ADJUSTMENT (VHS)

3.1 Precaution

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.

3.1.1 Required test equipments

• Color (colour) television or monitor

• Oscilloscope:

• Frequency counter

• Audio level meter

• Signal generator: RF / IF sweep / marker

• Unless otherwise specified, all measuring points and adjustment parts are located on the Main board.

3.1.5 EVR Adjustment

Some of the electrical adjustments require the adjustment performed by the EVR system. The main unit have EEPROMs for storing the EVR adjustment data and user setups.

Notes:

• In the EVR adjustment mode, the value is varied with the channel buttons (+, –). The adjusted data is stored when the setting mode changes (from PB to STOP, when the tape speed is changed, etc.). Take care to identify the current mode of each adjustment item when making an adjustment.

• When changing the address setting in the EVR adjustment mode, use the Jig RCU or the remote controller having numeric keypad with which a numeric code can be directly input. The remote control code of the Jig RCU corresponds to each of the digit keys on the remote controller as follows.

Digit-key 0 1 2 3 4 5 6 7 8 9 Code 20 21 22 23 24 25 26 27 28 29

• As the counter indication and remaining tape indication are not displayed FDP during the EVR adjustment mode, check them on the TV monitor screen.

• When performing the EVR adjustment, confirm that the FDP indication is changed to the EVR mode, as shown below.

(F1) from the Jig RCU. (6) Set the EVR address to (F2) by transmitting the code (F3)

from the Jig RCU. (7) Transmit the code (F4) from the Jig RCU to adjust so that

the A.PB FM level of the higher channel level becomes

the specified value (G1). (Adjust before recording, then

confirm it by playing back.) (8) If the specified value (G1) is not obtained, transmit the

code (F4) from the Jig RCU to adjust so that the wave-

form level of the lower channel level becomes the speci-

fied value (G2). (Adjust before recording, then confirm it

by playing back.) (9) Release the EVR mode of the VCR by transmitting the

code (F1) from the Jig RCU again. (When the EVR mode

is released, the adjusted data is memorized.)

ELECTRICAL ADJUSTMENT (DV)

3.6 PREPARATION

3.6.1 Precautions

(1) The DV section of this model is based on a special ad-

justment 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.

2

PROM (IC1504 on DV main board)

• E

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

unplugging a wire.
