INTRODUCTION
This
manual
provides
service
information
for
our
VHS
Video
Cassette
Recorder.
It
describes
the
principles
and
adjustments
of
mechanical
and
electrical
operation
for
this
model.
Service
procedures
given
herein
cover
only
field
maintenance
services.
Adjustments
which
require
high-level
instruments,
jigs,
and
techniques
are
excluded
since
they
should
be
performed
at
the
factory.
Due
to
design
modifications,
the
servicing
procedures
and
data
given
in
this
manual
are
subject
to
possible
change
without
prior
notice.
IMPORTANT
SAFETY
PRECAUTION
Prior
to
shipment
from
the
factory,
our

strictly
inspected
to
conform
with
the
recognized
product

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.
PRECAUTIONS DURING SERVICING

2.
In
addition
to
safety,
other
parts
and
assemblies
are
specified
for
conformance
with
such
regulations
as
those
applying
to
spurious
radiation.
These
must
also
be
replaced
only
with
specified
replacements.
Examples:

5.
When
replacing
AC
primary
side
components
(transformers,

securely
on
the
terminals
before
soldering.
6.
Observe
that
wires
do
not
contact
heat
producing
parts
(heatsinks,
oxide
metal
film
resistors,
fusible
resis-
tors,
etc.).
7.
Check
that
replaced
wires
do
not
contact
sharp
edged
or
pointed
parts.
8.
When
a
power
cord
has
been
replaced,
check
that
force
(maximum
applied
force
should
be
20-30
Ibs.)
in
any
direction
will
not
loosen
it.
9. Also check areas surrounding repaired locations.
10.
Use
care
that
foreign
objects
(screws,
solder
droplets,
etc.)
do
not
remain
inside
of
unit.
SAFETY CHECK AFTER SERVICING
1. Insulation resistance test
Confirm
specified
insulation
resistance
or
greater
between
power
cord
plug
prongs
and
externally
exposed
parts of the set (RF terminals, video and Output terminals, etc.).

1. MECHANISM CONTROL
The mechanism includes its own mode as well as the operation mode of the VCR as shown in the chart below. This mode serves
an important function in working to protect the tape by passing through the VCR when the mode is switched over.
The movement of the mechanism mode is performed by the control signal of the loading motor's rotary control circuit. With this
control, the operation mode position is detected by the Mode switch (4-bit mode data output), Cassetle In switch, tape top sensor
and the tape end semsor which detects all modes of the mechanism.
1-1. MODE SW
The composition of the 4 terminals, COM DATA 1, 2, 3, 4, are treated as a 4 bit signal.

4-3. TAPE TRANSPORT CHECK AT
THE TAKE-UP GUIDE
In general, no adjustment will be necessary for the take-
up guide. However, adjustments or checks will be
necessary when replacing the Audio/CTL Head or parts
affecting the tape transport system after a long period of
operation.
1. Using an ordinary cassette tape, set to PLAY mode.
2. Turn Audio/CTL Head screw O as shown in the
figure below and adjust for smooth transport at the
take-up guide as shown in Figure “Guide Roller” on
page MA-5.

ADJUSTMENT
Before using the test tape, make sure that the tape
transport is normal using an ordinary cassette tape.
Also, make sure that the switching point (Refer to EA) is
adjusted. If they are not, do the following checks after
adjusting.
5-1. PRELIMINARY CHECKS
1. FM Envelope Waveform Check
1. Connect the CH-1 oscilloscope to TP of PB ENV and
CH-2 to TP of CTL. At this time, trigger the
oscilloscope externally with the signal (RF Switching
Pulse) from TP of RFS.
2. Play the test tape (Stairstep).
З. Use the Channel Y / À buttons to tune the tracking
to center position. Adjust point @ (X value adjustment
point: test point reference P.MA-1) so that the FM
envelope outputat TP of PB ENV reaches a maximum.
MA-6
X position Adjusting Ji
. Using the Channel V/A buttons. Perform the
following 3 steps (5-7) by moving the TP of CTL
waveform in both positive (+) and negative (—)
directions in 3 ms increments.
. Refer to the figure below. Read the level of portion
(a) of the waveform. If the waveform is serrated at
point (a), adjust the level so that the serrations are as
smooth as possible (refer to the second figure).

6. As shown in the equation below, read the FM
waveform value at point (b) and make sure that:
© 20.75 or 20 log 2-25 dB
. Read the values at points (c) and (d) [drum input and
output] and make sure that:

20 log = = -2.5 dB and
20 log £ = -2.5 dB
NOTES:
. Read the minimum levels for (b), (c), and (d).
. If above checks yield normal results, proceed
to page MA-8 section "ADJUSTMENT".
. If defects are noted, perform the following FM
envelope waveform adjustment.
FM ENVELOPE WAVEFORM
ADJUSTMENT
. Asin Ше previous section, observe the FM waveform
and press the CHANNEL V / A buttons. Waveform
alterations must be nearly parallel to each other as
shown in Figure "Normal Waveform Examples" on
page MA-7.
. И the waveform changes as shown in the figure
below, adjustment is necessary.

1.
Connect the TP of PB ENV to the oscilloscope
CH-1. Atthis time, trigger the oscilloscope externally
with the signal (RF Switching Pulse) from TP of RFS.
. Play the test tape (Stairstep).
DRUM INPUT ADJUSTMENT
. Observe the FM envelope output wave at the TP of
PB ENV with the oscilloscope and press the
CHANNEL V / A buttons in both positive (+) and
negative (—) directions.
. Aofthe following figure shows incorrect waveforms.
With a standard screwdriver, adjust the transport
guide roller to flatten the peak of the FM envelope
waveform as shown in B.
NOTES:
1. If the guide roller rotates freely, tighten the
screw slightly.
2. Be sure to adjust the guide roller only by small
increments at a time to avoid damaging the
test tape.
In addition to observing the waveform, make
sure that there is no slipping of the tape or
curling at the drum lead.

2. DRUM OUTPUT ADJUSTMENT
1. Adjust the take-up guide roller so that the FM
envelope output flattens as shown in D of the figure
below.
NOTES:
1. Fine adjustments are not required at this time.
It is sufficient if the tape is engaged with the
guide and that the servo operates properly
(control signal picked up).
. If the tape separates from the take-up guide or
wrinkling occurs, screw © must have been
excessively tightened with respect to screw (9
and screw @, which is causing the Audio/CTL
Head to incline forward or backward. Use care
in adjusting screws ® and ©, and screw ©
evenly and observe that wrinkles are not
produced at the take-up guide.

1. Check for maximum FM output waveform, maximum
audio output, and be sure that there is no wrinkling on
the tape or other transport irregularities. When
finished, secure the guide rollers. (This must be
performed in STOP mode.)
2. Because the guide rollers are easily moved, use care
when securing.
3. After tightening the screws, perform the final inter-
changeability check.

To attach the Front Loading Assembly, follow the procedures below.
1) Twist the loading motor with your finger until it is in
EJECT mode.
2) Twist the FD Pinion Gear counterclockwise until it
stops. (The FD Face Gear is loose. )
3) Twist the FD face Gear counterclockwise until it
stops, then apply gentle pressure in the
counterclockwise direction.
4) In the position at step 2) , rotate the FD Pinion Gear
clockwise. After about 3 1/2 turns, the FD Pinion Gear
should begin to interlock with the FD Relay Gear.
Now twist the FD Pinion Gear until it stops. (The
assembly should now resemble Fig. 2)

PERIODIC MAINTENANCE
The following procedures are recommended for main-
taining optimum performance and reliability of this video
cassette recorder.
CLEANING
For cleaning, use a lint-free cloth or gauze dampened
with alcohol.
TAPE TRANSPORT SYSTEM
1. The following components should be cleaned after
every 500 hours of use.
Impedance Roller
Tension Post
Transport Slide Post
Supply Guide Roller
Take-up Slide Post
Take-up Guide Roller
Video Head & Drum System
Drum Ground
Drum Motor Shaft
Audio/CTL Head
Pinch Roller
Capstan
Reverse Guide Post
Full Erase Head
Tape Guide
F Post
2. Since the above parts come in direct contact with
video tape, they tend to collect dust particles. ЇЇ
allowed to accumulate, dust may lead to damage to
the video tape and above parts.
3. After cleaning with alcohol, allow the parts to dry
thoroughly before using a cassette tape.
NOTE:
* When cleaning the two video heads on the
upper drum, do not clean them with a vertical
stroke.
• Use only a gentle back and forth motion in the
direction of the tape path.
REEL DRIVE SYSTEM
1. The following components should be cleaned after
every 1000 hours of use.

2. The above revolving parts are of rubber or come in
direct contact with rubber parts. Dust on rubber
accumulates and interferes with proper operation.
3. Avoid using excessive alcohol when cleaning rubber
parts.
