Note: Nominal specifications represent the design specifications. All units should be able to approximate these.
Some will exceed and some may drop slightly below these specifications. Limit specifications represent the absolute worst condition that still might be considered acceptable. In no case should a unit fail to meet limit specifications.
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 customer, 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.

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-
1-2-1T6600SFTY
Page 6
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.
1-2-2T6600SFTY

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.

How to Remove / Install Flat Pack IC
Caution:
1.The Flat Pack-IC shape may differ by models. Use
an appropriate hot-air flat pack-IC desoldering machine, whose shape matches that of the Flat PackIC.
2. Do not apply the hot air to the chip parts around the
Flat Pack-IC for over 6 seconds as damage may
occur to the chip parts. Put Masking Tape around
the Flat Pack-IC to protect other parts from damage. (Fig. S-1-2)
3. The Flat Pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each
pin or solder lands under the IC when removing it.
1. Removal
With Hot - Air Flat Pack - IC Desoldering Machine:
a. Prepare the Hot - Air Flat Pack - IC Desoldering
Machine, then apply hot air to Flat Pack - IC (about
5~6 seconds). (Fig. S-1-1)
b. Remove the Flat Pack- IC with tweezers while
applying the hot air.
With Soldering Iron:
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. 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)
1-3-2T6600STA
Page 11
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.
2. Installation
a. Using desoldering braid, remove the solder from
the foil of each pin of the Flat Pack - IC on the CBA,
so you can install a replacement Flat Pack - IC
more easily.
b. The "I" mark on the Flat Pack - IC indicates pin 1
(See Fig. S-1-6). Make sure this mark matches the
1 on the CBA when positioning for installation.

of 7 sec. at SP, 14 sec. at LP, 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 S-REEL 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 terminal.
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.
After switch over to CASSETTE OUT operation and
then a laps of 5 sec. or more from the CASSETTE
OUT operation start, if LD-SW does not go to the
EJ position or if START Sensor and END Sensor
does not turn "ON" at the EJ position, the unit
starts again to insert CASSETTE.
(However in S-INH state, the START/END Sensor
shall be disabled).
b) CASSETTE OUT operating Malfunction
After a lapse of 5 sec. or more from CASSETTE
OUT operation start, if LD-SW does not go to the
EJ position or if START Sensor and END Sensor
does not turn "ON" at the EJ position, the unit
starts to insert CASSETTE.
(However in S-INH state, the START/END Sensor
shall be disabled).
When the unit switches over to CASSETTE insertion at CASSETTE IN or CASSETTE OUT Malfunction, if LD-SW does not go to the SB position
after a lapse of 5 sec. or more from CASSETTE
insertion start, the function shall immediately be
stopped and POWER be turned OFF, and the unit
be CASSETTE LOADING Malfunction.
c) When POWER is turned ON, if the CL position or
GC position cannot be detected after 5 sec. LDREV operation and 5 sec. LD-FWD operation, the
function shall immediately be stopped and POWER
be turned OFF, and the unit be CASSETTE LOADING Malfunction.
d) When POWER is turned ON without CASSETTE
(EJ position) and LD-SW is monitored all the time,
if the CL or GC position is detected continuously for
1 sec. or more, the POWER shall be turned OFF
and the unit be CASSETTE LOADING Malfunction.
Countermeasure for Mechanical
Malfunction
If the unit detects Mechanical Malfunction, turn the
POWER OFF. If the unit is Mechanical Malfunction,
Key input except POWER key shall be disabled and
CASSETTE insertion disabled. When POWER Key is
entered, the POWER is turned ON and the unit
switches over the EJECT Mode. (Return with POWER
ON)

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.

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.
To unload a cassette tape manually:
1. Disconnect the AC plug.
2. Remove the Top Case and Front Assembly.
3. Make sure that the Moving guide preparations are
in the Eject Position.
4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 until the Moving guide preparations come to the Eject Position. Stop turning when
the preparations begin clicking or can not be
moved further. However, the tape will be left wound
around the cylinder.
5. Turn the LDG Belt in the appropriate direction continuously, and the cassette tape will be ejected.
Allow a minute or two to complete this task.
B. Method to place the Cassette Holder in the tape-
loaded position without a cassette tape
1. Disconnect the AC Plug.
2. Remove the Top Case and Front Assembly.
3. Turn the LDG Belt in the appropriate direction
shown in Fig. M1. Release the locking tabs shown

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 preset 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.”

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.
