2.4 TAPE TRANSPORT ADJUSTMENT

In most cases the deck section is in need electrical ad-

justment, it results from replacement of worm mechanical

parts or video heads. In the event of malfunction with elec-

trical circuits, troubleshouting with the aid of proper test in-

struments most be done first, and then commence neces-

sary repair, replacement and adjustment, etc.

2.4.1 Back tension

1. Set a cassette torque meter onto the deck and measure

the back tension in standard REC mode to confirm that

the back tension is 0.7x10-3 –1.37x10-3 N•m.

2. If not, replace the tension band.

When the value widely fluctuates in the measurement,

replace the supply reel disk.

3. With the cassette torque meter, confirm that the play

torque is 1.47x10-3 –2.45x10-3 N•m.

If necessary, replace the center pully unit.

2. Connect the jig connector cable to CN25 on the MAIN

board as shwon on Fig. 2-6-1 (Page 2-10).

3. Observe signal at V. TP FM with external trigger from V.

4. Playback the SP stairstep signal of the alignment tape

and maximize the FM waveform by the tracking button.

5. Set the tracking control to the center position by simul-

taneously pressing the tracking (-) and (+) buttons and

maximize the FM waveform by the tracking button.

6. If the observed FM waveform is not flat, adjust the height

of the supply of take-up guide roller with the roller driver.

Note:

To prevent the tape from damage, turn the guide

rollers slowly.

7. By operating the tracking button (both in + and –direc-

tions) in the manual tracking mode, vary the output level

of the FM waveform from maximum to minimum and vice

versa to confirm that the waveform varies nearly in a flat

shape.

8. When the FM waveform breaks in the level varying proc-

ess, subtly adjust the height of guide rollers at every

breaking point so that the waveform varies as flat as pos-

sible.

Repeat the above steps 6. and 7. several times to con-

firm that the waveform is flat as a whole.

9. Playback the SP stairstep signal of alighment tape and

adjust the tracking control to maximize the FM wave-

form, confirm that FM waveform variation is always flat.

10. Record the signal and play it back in both of the SP and

LP modes, and confirm that the FM waveform is flat in

both modes.

Note:

Among the above-mentioned adjustment steps,

the items of No.9 and No.10 are needed for the

LP model only.

wrinkling and damage in the tape around the pinch roller

and TU guide pole whenever the deck is in operation of

Loading/Unloading, Search Rewind and at mode change

from Search Rewind to play mode. If wrinkling or dam-

age in the tape occurs around the TU guide pole, ad-

just the angle (slant) of the A/C head to the tape. So that

the tape normally runs along the lower flange of the guide

pole.

tons and confirm that the FM output level is maximum at

the center position as shown in Fig. 2-4-8.

4. If necessary, slightly loosen the setscrews Dand Eand

Table 2-5-1 Specific oil and grease to be used

2.5 REMARKS

2.5.1 Cleaning

1. For cleaning of the upper drum (particularly video

heads), use fine-woven cotton cloth or Kimwipe with al-

cohol soaks through. Do not move the cloth but turn the

upper drum counterclockwise.

Note: Make sure not to move the cloth in the vertical di-

rection to the video head, since it may cause damage

of the video heads.

2. For cleaning of parts of the tape transport system ex-

cept the upper drum, use fine-woven cotton cloth or cot-

ton swab soaked alcohol.

3. After cleaning, confirm that the cleaned parts are com-

pletely dry before loading the deck with cassette tape.

2.5.2 Applying oil and grease

1. Periodical oiling and greasing are not required but should

be done to new parts when replacing. If oil and grease

on the other parts of the other party are old and dirty,

wipe them clean and apply new oil or grease.

2. For parts and points to apply oil and grease, refer to the

exploded view of the mechanism assembly (M3).

Table 2-5-1pecifies oil and grease to be used.

3. When oiling, clean the objective parts with alcohol first

and apply one or two drop(s) of oil. Too much oiling

causes rotary parts to slip because of oil leakage.

2.5.3 Checkup

After replacement of the supply reel disk and tension band,

make sure to inspect back tension according to the adjust-

ment procedure of MECHANISM ADJUSTMENT section.

3.1 ELECTRICAL ADJUSTMENT

3.1.1 PREPARATION

1. Precaution

This model does not contain adjustment controls (VR).

General deck system, camera system and monitor system

adjustment are not required. However, if MAIN board and

MONITOR board need replacement, please use original E

2 PROM on to new board. Then adjustment are not required.

And if parts such as the following need replacement, spe-

cial computerized adjustment are required (Refer to sec.

3.1.1- 4). Please contact to JVC Service for detaile informa-

tion.

• OP block

• EEP ROM (IC102 of MAIN board)

• MONITOR

In the event of malfunction with electrical circuits, trouble-

shooting with the aid of proper test instruments most be done

first, and then commence necessary repair, replace-ment

and adjustment, etc.

1. In case of wiring to chip test points for measurement,

use IC clips, etc. to avoid any stress.

2. Since connectors are fragile, carefully handle them in dis-

connecting and connecting.

3. Shortcircuit between operation un it and DECK chassis.

2. Required test equipment

1. Color TV monitor.

2. AC power adapter

3. Oscilloscope (dual-trace type, observable 100 MHz or

higher frequency)

* It is recommended to use one observable 300 MHz or

higher frequency.

4. Digital voltmeter

5. Frequency counter (with threshold level adjuster)

6. Personal computer
