IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the factory, our products are strictly inspected for 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.
Safety Precautions for TV Circuit
1. Before returning an instrument to the custom-
er, always make a safety check of the entire instru-
ment, including, but not limited to, the following
items:
a. Be sure that no built-in protective devices are de-
fective and have been defeated during servicing.
(1) Protective shields are provided on this chassis
to protect both the technician and the customer.
Correctly replace all missing protective shields, including any removed for servicing convenience. (2)
When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all
protective devices, including but not limited to,
nonmetallic control knobs, insulating fishpapers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not oper-
ate this instrument or permit it to be operated
without all protective devices correctly installed and functioning. Servicers who defeat
safety features or fail to perform safety checks
may be liable for any resulting damage.
b. Be sure that there are no cabinet openings through
which an adult or child might be able to insert their
fingers and contact a hazardous voltage. Such
openings include, but are not limited to, (1) spacing
between the picture tube and the cabinet mask, (2)
excessively wide cabinet ventilation slots, and (3)
an improperly fitted and/or incorrectly secured
cabinet back cover.
c. Antenna Cold Check - With the instrument AC
plug removed from any AC source, connect an
electrical jumper across the two AC plug prongs.
Place the instrument AC switch in the on position.
Connect one lead of an ohmmeter to the AC plug
prongs tied together and touch the other ohmmeter lead in turn to each tuner antenna input exposed terminal screw and, if applicable, to the
coaxial connector. If the measured resistance is
less than 1.0 megohm or greater than 5.2 megohm, an abnormality exists that must be corrected
before the instrument is returned to the customer.
Repeat this test with the instrument AC switch in
the off position.
d. Leakage Current Hot Check - With the instru-
ment completely reassembled, plug the AC line
cord directly into a 120V AC outlet. (Do not use an
isolation transformer during this test.) Use a leak-
age current tester or a metering system that complies with American National Standards Institute
(ANSI) C101.1 Leakage Current for Appliances
and Underwriters Laboratories (UL) 1410, (50.7).
With the instrument AC switch first in the on position and then in the off position, measure from a
known earth ground (metal water pipe, conduit,
etc.) to all exposed metal parts of the instrument
(antennas, handle brackets, metal cabinet, screw
heads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current
measured must not exceed 0.5 milli-ampere. Reverse the instrument power cord plug in the outlet
and repeat the test.

BEFORE RETURNING THE INSTRUMENT TO
THE CUSTOMER OR BEFORE CONNECTING
THE ANTENNA OR ACCESSORIES.
e. X-Radiation and High Voltage Limits - Because
the picture tube is the primary potential source of
X-radiation in solid-state TV receivers, it is specially constructed to prohibit X-radiation emissions.
For continued X-radiation protection, the replacement picture tube must be the same type as the
original. Also, because the picture tube shields
and mounting hardware perform an X-radiation
protection function, they must be correctly in place.
High voltage must be measured each time servic-
1-2-1SFTY_2
Page 7
ing is performed that involves B+, horizontal deflection or high voltage. Correct operation of the
X-radiation protection circuits also must be reconfirmed each time they are serviced. (X-radiation
protection circuits also may be called "horizontal
disable" or "hold down.") Read and apply the high
voltage limits and, if the chassis is so equipped,
the X-radiation protection circuit specifications given on instrument labels and in the Product Safety
& X-Radiation Warning note on the service data
chassis schematic. High voltage is maintained
within specified limits by close tolerance safety-related components/adjustments in the high-voltage
circuit. If high voltage exceeds specified limits,
check each component specified on the chassis
schematic and take corrective action.
2. Read and comply with all caution and safety-related notes on or inside the receiver cabinet, on the
receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of this TV receiver. Design alterations and additions, including,
but not limited to circuit modifications and the addition of items such as auxiliary audio and/or video
output connections, might alter the safety characteristics of this receiver and create a hazard to the
user. Any design alterations or additions will void
the manufacturer's warranty and may make you,
the servicer, responsible for personal injury or
property damage resulting therefrom.
4. Picture Tube Implosion Protection Warning -
The picture tube in this receiver employs integral
implosion protection. For continued implosion protection, replace the picture tube only with one of
the same type number. Do not remove, install, or
otherwise handle the picture tube in any manner
without first putting on shatterproof goggles
equipped with side shields. People not so
equipped must be kept safely away while picture
tubes are handled. Keep the picture tube away
from your body. Do not handle the picture tube by
its neck. Some "in-line" picture tubes are equipped
with a permanently attached deflection yoke; because of potential hazard, do not try to remove
such "permanently attached" yokes from the picture tube.
5. Hot Chassis Warning -
a. Some TV receiver chassis are electrically connect-
ed directly to one conductor of the AC power cord
and maybe safety-serviced without an isolation
transformer only if the AC power plug is inserted
so that the chassis is connected to the ground side
of the AC power source. To confirm that the AC
power plug is inserted correctly, with an AC voltmeter, measure between the chassis and a known
earth ground. If a voltage reading in excess of 1.0V
is obtained, remove and reinsert the AC power
plug in the opposite polarity and again measure
the voltage potential between the chassis and a
known earth ground.
b. Some TV receiver chassis normally have 85V
AC(RMS) between chassis and earth ground regardless of the AC plug polarity. This chassis can
be safety-serviced only with an isolation transformer inserted in the power line between the receiver
and the AC power source, for both personnel and
test equipment protection.
c. Some TV receiver chassis have a secondary
ground system in addition to the main chassis
ground. This secondary ground system is not isolated from the AC power line. The two ground systems are electrically separated by insulation
material that must not be defeated or altered.
6. Observe original lead dress. Take extra care to assure correct lead dress in the following areas: a.
near sharp edges, b. near thermally hot parts-be
sure that leads and components do not touch thermally hot parts, c. the AC supply, d. high voltage,
and e. antenna wiring. Always inspect in all areas
for pinched, out of place, or frayed wiring. Check
AC power cord for damage.
7. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged
should be replaced with components, parts, or wiring that meet original specifications. Additionally,
determine the cause of overheating and/or damage and, if necessary, take corrective action to remove any potential safety hazard.
8. Product Safety Notice - Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual
inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc.. Parts
that have special safety characteristics are identified by a ( # ) on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create shock, fire, and/or
other hazards. The Product's Safety is under review continuously and new instructions are issued
whenever appropriate. Prior to shipment from the
factory, our products are strictly inspected to confirm 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.
1-2-2SFTY_2
Page 8
Precautions during Servicing
A. Parts identified by the ( # ) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before soldering.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. When a power cord has been replaced, check that
5~6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Use care that foreign objects (screws, solder drop-
lets, etc.) do not remain inside the set.
K. Crimp type wire connector
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, in order to
prevent shock hazards, perform carefully and precisely the following steps.
Replacement procedure
1) Remove the old connector by cutting the wires at
a point close to the connector.
Important: Do not re-use a connector (discard it).
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.
3) Align the lengths of the wires to be connected. Insert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve at
the center position. Be sure to crimp fully to the
complete closure of the tool.
L. When connecting or disconnecting the VCR con-
nectors, first, disconnect the AC plug from AC supply socket.

which is applied to all pins of the Flat Pack - IC, you
can remove it easily. (Fig. S-1-3)
b. Lift each lead of the Flat Pack - IC upward one by
one, using a sharp pin or wire to which solder will
not adhere (iron wire). When heating the pins, use
a fine tip soldering iron or a hot air Desoldering
Machine. (Fig. S-1-4)
With Iron Wire:
a. Using desoldering braid, remove the solder from all
pins of the Flat Pack - IC. When you use solder flux
which is applied to all pins of the Flat Pack - IC, you
can remove it easily. (Fig. S-1-3)
b. Affix the wire to a workbench or solid mounting
point, as shown in Fig. S-1-5.
c. Pull up on the wire as the solder melts so as to lift
the IC leads from the CBA contact pads, while
heating the pins using a fine tip soldering iron or
hot air blower.
Note:
When using a soldering iron, care must be taken
to ensure that the Flat Pack - IC is not being held
by glue, or when it is removed from the CBA, it
may be damaged if force is used.

Mechanical Malfunction determination
1) REEL Malfunction detection
Countermeasure for REEL and CAPSTAN motor
After the Malfunction detection with REEL/CAPSTAN sensor, the unit shall switch over to STOP
(B) and be REEL Mechanical Malfunction.
a) If the T-REEL pulse is not impressed after a lapse
of 5 sec. at SP, 10 sec. at LP, 14 sec. at SLP, or
more in the REEL Rotation Mode like PLAY/REC,
FS/RS Mode, and the T-REEL or S-REEL pulse is
not impress after a lapse of 4 sec. or more in REEL
Rotation Mode of FF/REW, it shall be assumed to
stop the rotation and switch over to STOP (B) position, then POWER be turned OFF and the unit be
REEL Mechanical Malfunction. (T-REEL and SREEL for the models on S-REEL and only T-REEL
for other models)
b) If the C-FG pulse is not impressed for a lapse of 1
sec. or more during the CAPSTAN MOTOR rotation, it shall be MOTOR Rotation Malfunction
(REEL Malfunction).
2) DRUM Malfunction detection
Detect the DRUM rotation at the D-FG input termi-
nal.
If the variation of D-FG input level is not detected
for a lapse of 1 sec. or more when D-CONT is "H",
it shall be assumed to be Rotation Malfunction and
be DRUM Malfunction.
When detect Drum Malfunction, POWER shall be
turned OFF after the unit switches over to STOP
(B) Mode.
3) Countermeasure for TAPE LOADING Malfunction
Detect the Malfunction with the LOADING Switch.
a) TAPE LOADING Malfunction
If LD-SW does not go to the established position
after a lapse of 7 sec. or more from TAPE LOADING or TAPE UNLOADING start, the LOADING
function shall immediately be stopped and POWER
be turned OFF, and inform the Timer about the
LOADING Mechanical Malfunction.
b) LD-SW Position Malfunction at each mode
When the unit operates at each mode, even if the
LD-SW position changes from the established one
in its mode, it keeps the function according to its
mode.
4) Countermeasure for CASSETTE LOADING Malfunction
a) CASSETTE IN operating Malfunction
If LD-SW does not go to SB position after a lapse of
5 sec. or more from the CASSETTE insertion start,
the unit starts the CASSETTE OUT operation.

Power Supply Trouble Shooting Guide
It is highly recommended that a variable isolation
transformer which can monitor current be used.
(Alternatively a variable AC source which monitors
current will do). Read directions below before
power is added!
CHECK
Repair method
Check Fuse (F601) is blown
out or not.
If fuse is blown out,
YES

do repair method #1
NO
Check whether the primary
rectifying DC of the Switching
power supply has an output.
NO

(Reading should be about 168V.
YES
Voltage of the 105V line
higher than normal?
YES
#3
NO
The transformer of the power
supply makes a higher sound
or the oscillation wave form is
abnormal.
(E.g. intermittent oscillation)
Connect the positive probe of
oscilloscope to the pin 16 of

Fig.1
Repair method #1
(Power must be off)
Short circuit in the secondary side. check diode D613,
D614, D616, D617 and D618, switching transistor
(Q601), control transistor (Q602), diode and resistor
replace as necessary.
Disconnect 105V diode (D613), 25V diode (D614), 8V
diode (D616), 12V diode (D617), 12V diode (D618)
and Check the load continuity of 105V line, 25V line,
8V line, 12V line through a tester (resistance range).
If the tester indicates a lower resistance value around
0 ohm, the line is short-circuited.
Before repairing the switching power supply, find out
the short-circuited area of such line and repair it.
If the tester does not indicate any low resistance value
(around 0 ohm), no load is short-circuited and there is
no problem.
Check for any defective parts while the secondary rectifying diodes are disconnected (D613, D614, D616,
D617 and D618) perform a diode check in both forward and reverse directions through a tester.
NO
There is no problem on the
SW power supply
1-8-15T5300TR1
Page 38
Repair method #2
Check the primary rectifying diodes (D603-D606) as
possible problems. Remove the above mentioned
parts and check them. Perform check according to the
step 1 and 2 of repair method #1 and check for defects
following parts, then if necessary replace with factory
originals.
R602 is open or not.
Q601, Q602, D607, D608 and D611 are short or not.
Repair method #3
The feedback circuit which is monitored by the output
of D613 105V may not work and this may be regarded
as a possible cause, remove IC601 (Photo Coupler),
diode (D620) and transistor (Q604) check for defects.
Repair method #4
Check control circuitly which is connecting to Pin 2
and 1 of Switching Transformer T601.

Standard Notes
Warning
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage,
etc. Replacement parts that have these special safety
characteristics are identified in this manual and its
supplements; electrical components having such features are identified by the mark " # " in the schematic
diagram and the parts list. Before replacing any of
these components, read the parts list in this manual
carefully. The use of substitute replacement parts that
do not have the same safety characteristics as specified in the parts list may create shock, fire, or other
hazards.

starts on the next page. Refer to the information below
on this page if a tape gets stuck, for example, in the
mechanism due to some electrical trouble of the unit.
Service Information
A. Method for Manual Tape Loading/Unloading
To load a cassette tape manually:
1. Disconnect the AC plug.
2. Remove the Top Case and Front Assembly.
3. Insert a cassette tape. Though the tape will not be
automatically loaded, make sure that the cassette
tape is all the way in at the inlet of the Cassette
Holder. To confirm this, lightly push the cassette
tape further in and see if the tape comes back out,
by a spring motion, just as much as you have
pushed in.
4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 for a minute or two to complete
this task.

1-A. Preliminary/Final Checking and
Alignment of Tape Path
Purpose:
To make sure that the tape path is well stabilized.
Symptom of Misalignment:
If the tape path is unstable, the tape will be damaged.
Note: Do not use an Alignment Tape for this proce-
dure. If the unit is not correctly aligned, the tape may
be damaged.
1. Playback a blank cassette tape and check to see
that the tape runs without creasing at Guide Rollers
[2] and [3], and at points A and B on the lead surface. (Refer to Fig. M3 and M4.)
2. If creasing is apparent, align the height of the guide
rollers by turning the top of Guide Rollers [2] and
[3] with a Guide Roller Adj. Screwdriver. (Refer to
Fig. M3 and M5.)

1-B. X Value Alignment
Purpose:
To align the Horizontal Position of the Audio/Control/
Erase Head.
Symptom of Misalignment:
If the Horizontal Position of the Audio/Control/Erase
Head is not properly aligned, maximum envelope cannot be obtained at the Neutral position of the Tracking
Control Circuit.
1. Connect the oscilloscope to TP402 (ENV.) and
TP201 (CTL) on the Main CBA. Use J274 (RF-SW)
as a trigger.
2. Playback the Gray Scale of the Alignment Tape
(FL8N) and confirm that the PB FM signal is
present.
3. Set the Tracking Control Circuit to the center position by pressing CH UP button then “ PLAY ” button
on the unit. (Refer to note on bottom of page
2-3-4.)
4. Use the X-Value Adj. Screwdriver so that the PB
FM signal at TP402 (ENV.) is maximum. (Fig. M6)
5. Press CH UP button on the unit until the CTL waveform has shifted by approx. +2msec. Make sure
that the envelope is simply attenuated (shrinks in
height) during this process so that you will know the
envelope has been at its peak.

6. Press CH DOWN button on the unit until the CTL
waveform has shifted from its original position (not
the position achieved in step 5, but the position of
CTL waveform in step 4) by approximately -2msec.
Make sure that the envelope is simply attenuated
(shrinks in height) once CTL waveform passes its
original position and is further brought in the minus
direction.
7. Set the Tracking Control Circuit to the center position by pressing CH UP button and then “ PLAY ”
button.
1-C. Checking/Adjustment of Envelope
Waveform
Purpose:
To achieve a satisfactory picture and precise tracking.
Symptom of Misalignment:
If the envelope output is poor, noise will appear in the
picture. The tracking will then lose precision and the
playback picture will be distorted by any slight variation of the Tracking Control Circuit.
1. Connect the oscilloscope to TP402 (ENV.) on the
Main CBA. Use J274 (RF-SW) as a trigger.
2. Playback the Gray Scale on the Alignment Tape
(FL8N). Set the Tracking Control Circuit to the center position by pressing CH UP button and then “
PLAY ” button on the unit. Adjust the height of
Guide Rollers [2] and [3] (Fig. M3, Page 2-3-3)
watching the oscilloscope display so that the envelope becomes as flat as possible. To do this adjustment, turn the top of the Guide Roller with the
Guide Roller Adj. Screwdriver.
3. If the envelope is as shown in Fig. M7, adjust the
height of Guide Roller [2] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.
4. If the envelope is as shown in Fig. M8, adjust the
height of Guide Roller [3] (Refer to Fig. M3) so that
the waveform looks like the one shown in Fig. M9.
5. When Guide Rollers [2] and [3] (Refer to Fig.M3)
are aligned properly, there is no envelope drop
either at the beginning or end of track as shown in
Fig. M9.
Note: Upon completion of the adjustment of Guide
Rollers [2] and [3] (Refer to Fig. M3), check the X
Value by pushing the CH UP or DOWN buttons alternately, to check the symmetry of the envelope. Check
the number of pushes to ensure center position. The
number of pushes CH UP button to achieve 1/2 level of
envelope should match the number of pushes CH
DOWN button from center. If required, redo the “X
Value Alignment.”
1-D. Azimuth Alignment of Audio/Con-
trol/ Erase Head
Purpose:
To correct the Azimuth alignment so that the Audio/
Control/Erase Head meets tape tracks properly.
Symptom of Misalignment:
If the position of the Audio/Control/Erase Head is not
properly aligned, the Audio S/N Ratio or Frequency
Response will be poor.
1. Connect the oscilloscope to the audio output jack
on the rear side of the deck.
2. Playback the alignment tape (FL8N) and confirm
that the audio signal output level is 8kHz.
3. Adjust Azimuth Adj. Screw so that the output level
on the AC Voltmeter or the waveform on the oscilloscope is at maximum. (Fig. M6)
Dropping envelope level at the beginning of track.

ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape
loading/unloading mechanism. Since information
about the state of the mechanism is provided to the
System Control Circuit only through the Mode Switch,
it is essential that the correct relationship between
individual gears and levers be maintained.
All alignments are to be performed with the mechanism in Eject mode, in the sequence given. Each
procedure assumes that all previous procedures have
been completed.
IMPORTANT:
If any one of these alignments is not performed
properly, even if off by only one tooth, the unit will
unload or stop and it may result in damage to the
mechanical or electrical parts.
