2-2-3. How To Check The Mechanism Mode
Position
You can tell which mode the mechanism is currently in by
looking at the codes and marking-lines on the crescent
slide on the underside of the mechanism chassis. The edge
of the crescent mounting is used as the reference line, as
shown in Fig. 2-2-2, and the marking-lines and symbols
indicating the mechanism modes are displayed on the
crescent slide, which slides against the edge of the crescent
mounting. The mechanism mode is read off from the
marking-line on the slide crescent which is aligned with
the reference-line on the crescent mounting.
Example: In Fig. 2-2-2, marking-line 6 is aligned with the
reference-line on the crescent mounting, so the mechanism is seen to be in FF/REW mode.
The edge of the
crescent mounting
is the reference-line.

3. Disassembling the Main Parts of
the Mechanism
3-1-1. Operating the Loading Motor by the
Manual Method
Points to Note
. When fitting the parts of the mechanism, refer to the
“Assembly Notes”, and proceed in the reverse of disassembly order.
. Dis-assembly and assembly should be carried out in
EJECT mode unless a movement mode is explicitly
specified. EJECT mode is the state in which the cas-sette
tape has been ejected.
. Clamps are used to prevent parts coming loose. When
removing a clamp, be careful not to force it, as this can
result in damage.
1. Refer to Section 3-2 and install the mechanism unit.
2. Using your finger, turn the loading motor located at
the rear of the mechanism unit. For EJECT, turn the
loading motor in the direction of the arrow on the
loading motor. For PLAY or FF/REW, turn it in the
opposite direction.
When rotating the loading motor in the EJECT direction with a tape slacken, stop the rotation of the
loading motor before beginning front unloading.
Rotate the capstan motor with your hand, wind the
slacked part of the tape, and rotate the loading motor
in the EJECT direction again.
When carrying out front loading, release the lock by
pressing down the tray lock lever 8 and the lid
opener lever 9 of the cassette mechanism assembly
(shown in Fig. 3-2-2).
3-1. How to Make the Mechanism Move
In order to check a movement such as front loading, fron
unloading, tape loading, tape unloading, raising/lower-in
and pressing the pinch roller, you will need to operat
the loading motor. There are two methods of operatin
the loading motor, and these are explained in sections 3
1-1. The above movements can also be performed with-ou
operating the loading motor, by following the metho
explained in Section 3-1-2.

. The measurements must be taken without any incandescent light or daylight.
. If the mechanism cannot be put into PLAY, FF or REW
mode by the method described in 1) above, make a
dummy cassette tape, as shown in Fig. 4-1-2. The
dummy cassette tape is made as follows: Unscrew the
five screws on the underside, remove the reels, leaf
springs and other parts on the supply and take up sides,
make holes in the upper surface as wide as the reel
diameter, then assemble the parts.
2. Put the mechanism into REW mode, wait at least 10
seconds, then measure the torque value of the reel
table on the supply side. It should be at least 600 g.cm.
Take the measurement with the torque dial gauge
(VHJ-0004) held in position in your hand (lock
torque).
While taking the measurement, rotate the reel table
(take up reel assembly) on the take up side with your
hand so that the reel sensor does not respond.
3. After switching to FF mode, wait for at least 10
seconds and then measure the torque value of the reel

4-2-1. BT Lever Pole Position Adjustment
1. Without loading a cassette tape, put the mechanism
into PLAY mode (turn the power switch OFF).
2. Adjust point A on the band brake assembly by
rotating it so that the tip of the BT lever assembly is
aligned with the line on the right side of the mechanism chassis. The mechanism should be in EJECT
mode when adjusting the BT Lever assembly position.
3. Refer to Section 4-2-2 and check that the back tension
torque is between 25 and 50g.cm.
Align the end of the BT lever assembly
with this line.
4-3. Tape Path Adjustment
In normal circumstances, the tape path system does not
need to be adjusted. However, after removing or replacing
one of the parts shown in Fig. 4-3-1, you should check and
adjust the tape path. The adjustment of the tape path is
carried out while monitoring the envelope waveform of the
video head output, using an oscilloscope. To make sure
that the tape drawn off the reel runs freely and without
excessive tension along all the tape guides and cylinders
(drums), it is also important to check each tape guide by
eye.

4-3-1. Adjustment Procedure
1. Alignment tape or blank cassette tape, according to the
transmission system of the VCR you are repairing.
Models with 525 scanning lines and a field frequency
of 60H
2. Clean the tape guides, the cylinder (drum), the capstan
Shaft, the audio R/P head (ACE head) and the full
erase head.
3. Using an oscilloscope, adjust the height of the guide
roller and carry out horizontal position adjustment,
height adjustment and azimuth adjustment on the
audio R/P head (ACE head). When observing the
envelope waveform, bring the CH-1 probe into contact
with the envelope waveform (ENV) test point, and
bring the CH-2 probe into contact with the switching
pulse (SW P) test point. While adjusting the tape path,
set the trigger at the low side of the switching pulse
(SW P) in order to observe the output waveform on the
CH-1 side of the video head.
n
The contact point for the oscilloscope varies from one
model to another, so to find the correct point for your
model, refer to the figure entitled “Step 5 Test point for
tape path adjustment” in this section.
4. When checking the tape path by eye, use a dental
mirror.
4-3-2. Load Lever Assembly Height
Adjustment
1. Refer to Sections 3-9-2, and remove the opener
mounting .
2. Position the height adjustment tool (VHJ-0111) 3
under the full surface of the protrusion 2 on the load
lever assembly 1, as shown in Fig. 4-3-2.
3. Using your fingers, gently screw the adjustment nut
4 clockwise into the nut box (VHJ-0048) 5 until the
protrusion 2 of the load lever assembly 1 touches
the height adjustment tool (VHJ-0111) 3 and the
screw starts to feel tight. Next, loosen the adjustment
nut 4 by 270 d counterclockwise. .
4. Load a cassette tape (T-160). Wind the tape to the
beginning, and repeat FF ↔ REV five times (repeat
for the same portion 30 to 60 seconds).
If the bottom edge of the tape breaks, rotate the
adjustment 4 nut in the counterclockwise direction
by about 90 d. Repeat FF ↔ REV five times again and
check that the tape edge does not break (adjust again if
it does). Next, repeat CUE ↔ REV five times and
check that the tape is not damaged. If damaged, rotate
the adjustment nut in the clockwise direction by about
90 d. Repeat FF ↔ REW and CUE ↔ REV and check
that the tape is not damaged.
Arrange the equipment so that the whole surface of the
projection on the load lever assembly is positioned over
the height adjustment tool (VHJ-0111) when seen from
directly overhead.

4-3-3. Guide Roller Height Adjustment
1. Playback the Alignment Tape (VHJ-0006) and check
that the envelope waveform is at its maximum at the
tracking centre. Then, after loosening the S guide
roller and the T guide roller by rotating them counterclockwise, tighten them in turn until the envelope
waveform becomes flat. If the envelope waveform is
not at its maximum at the tracking centre, refer to
Section 4-3-4 and carry out a rough adjustment of the
horizontal position of the audio R/P head (ACE head)
before adjusting the guide rollers.
2. Adjust the S guide roller.
1 Playback the alignment tape (VHJ-0006). Press the
tracking (_) button, and check whether, when the
envelope waveform has reached 50 % of its
maximum, the front half of the envelope waveform
is flat. If not, fine-tune the S guide roller as
follows.
a. If the front half of the envelope waveform is as
shown in Fig. 4-3-4 (a), this means that you have
pressed the S guide roller too far. Therefore, loosen
it slightly, and when it is in the state shown in Fig.
4-3-4 (b), tighten it again, stopping when the
envelope waveform is flat.
b. If the front half of the envelope waveform is as
shown in Fig. 4-3-4 (b), this means you have not
pressed the S guide roller far enough. Therefore,
tighten it slightly, stopping when the envelope
waveform becomes flat.
c. If the front half of the envelope waveform is as
shown in Fig. 4-3-4 (c), it may happen that when
you tighten the S guide roller, the wrapper waveform does not disappear, but sinks into the flat part,
as shown in Fig. 4-3-4 (d). If this happens, the
status shown in Fig. 4-3-4 (c) is normal, so loosen
the S guide roller, then tighten it again until the
envelope waveform is as shown in Fig. 4-3-4 (c).
2 Check that at the tracking centre, the output of the
front half of the envelope waveform is not less than
80 % of the maximum.
3 Rotate the S guide roller 20 d counterclockwise.
3. Adjust the T guide roller.
1 Playback the alignment tape (VHJ-0006,). Press
the tracking (_) button and check whether, when
the envelope waveform is 50 % of maximum, the
back half of the envelope waveform is flat. If not,
loosen the T guide roller slightly, then tighten it
gradually until the back half of the envelope
waveform becomes flat.
2 Check that the output for the back half of the
envelope waveform is at its maximum at the
tracking centre.
2-36
4. Check that the envelope waveform does not fluctuate
when you switch from CUE to PLAY or from REV to
PLAY. If the front half of the envelope waveform does
fluctuate, tighten the S guide roller 1 d to 20 d. If the
back half of the envelope waveform does fluctuate,
repeat steps 3 and 4.

Adjustment, Azimuth Adjustment and
Horizontal Position Adjustment
1. Hight/azimuth adjustment
1. Refer to Section 4-3-3, complete the GUIDE ROLLER
adjustment, and perform the AUDIO R/P HEAD
adjustment.
As the audio R/P head assembly (ACE HEAD) has
been temporarily adjusted before shipment, do not
rotate screws unnecessarily.
2. Mark screw A, screw B, and bracket with a waterproof marker so that their original positions can be
known even after the screws are rotated.
Marking screws A and B in the same direction will
enable the adjustment mentioned later to be performed
easily.
3. Play the alignment tape (VHJ-0005), and observe the
audio output waveform using an oscilloscope.
Loosen screw B in the counterclockwise direction to
decrease the audio output level. Then tighten it in the
clockwise direction until the maximum level. Tighten
further in the clockwise direction to decrease the level,
and loosen in the counterclockwise direction until the
maximum level.
4. Rotate screw A in the same direction by the same
degree as screw B in step 1. (Check visually according to the mark made. )
5. Play the alignment tape (VHJ-0006), rotate screw C,
and maximize the audio output waveform (temporary
azimuth adjustment).
6. Perform the adjustments in 3 to 5 again.
7. Perform fine adjustments using screw B.
Perform the same adjustments as 3, and if screw B
was adjusted by more than 30 degrees, perform the
adjustment in step 4 again, and then perform fine
adjustments.
8. Play the alignment tape (VHJ-0006), rotate screw C,
and maximize the audio output waveform (actual
azimuth adjustment)
2. Horizontal position adjustment
1. Play the alignment tape (VHJ-0006).
2. Press the tracking buttons (tracking + and tracking _)
simultaneously and set the tracking to the centre.
3. Using an oscilloscope, observe the waveform of the
video head output.
4. Loosen the two fixed screws on the audio R/P head
(ACE head) by between 20 d and 30 d anticlockwise. .
5. Using a slotted screwdriver, adjust the position of the
audio R/P head (ACE head). At the position where the
amplitude of the envelope waveform is at its maximum
at the tracking centre, tighten the fixed screw on the
audio R/P head (ACE head). When you do this, check
that the envelope waveform changes equally whether
the tracking is shifted by pressing the tracking button
in the plus or the minus direction.
6. Play the alignment tape (VSJ-1001) and check that the
amplitude of the envelope waveform is at its maximum
at the tracking centre. If not, repeat steps 1 to 6.
7. Refer to the electrical adjustments section of the
service manual, and adjust the switching position of
the servo circuit.
Note:
1. When you press the tracking buttons (tracking + and
tracking _) simultaneously, the tracking is reset to the
tracking centre. When the tracking is at the tracking
centre, the message “TR -: -” will appear in place of
the clock display on the front panel. If you keep
pressing the tracking _ button the messages “TR -: ”
and “TR --: ” will appear, while if you keep pressing
the tracking + button, the messages “TR : -” and “TR :

4-3-5. Checking After Adjustment
1. Play the alignment tape (VHJ-0006) and check that the
envelope waveform is activated immediately and that
there are no fluctuations in the envelope waveform or
the audio output waveform.
2. Load a cassette tape (T-120) and use it to record and
replay. Check that the envelope waveform is activated
immediately and that there are no fluctuations in the
envelope waveform or the audio output waveform.
(When recording on the tape, input 1kHz to the audio
input terminal. Use a scratch-free cassette tape (T120). )
Check that at the tracking centre, the front half down
and back half down are not more than 20 % of the
value at the point where the envelope waveform
amplitude is at its maximum.
3. Check that the envelope waveform is activated
immediately when you switch from PLAY to REV or
from REV to PLAY. Check that there is no slack in the
tape next to the pinch roller.
4. Check that the envelope waveform is activated
immediately when you switch to PLAY from FF,
REW, CUE, REV or STOP mode. Check that there is
no slack in the tape next to the pinch roller.
5. Check that the tape is not curling or riding up on the
upper or lower flanges of the tape guides in PLAY, FF,
REW, CUE or REV modes.
6. Check that in PLAY mode, the tape runs as shown in
Fig. 4-3-7.

SAFETY CHECK-OUT
After correcting the original service problem,
perform the following safety checks before
releasing the set to the customer :
Check the metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC
leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to
any exposed metal part having a return to
chassis, must not exceed 0.5 mA. Leakage
current can be measured by any one of three
methods.
1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The
Data Precision 245 digital multimeter is
suitable for this job.
3. Measuring the voltage drop across a resistor
by means of a VOM or battery-operated AC
voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM
that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range
are suitable. (See Fig. A)
