IMPORTANT SAFETY PRECAUTIONS
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 carefully 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.
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
edges 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. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. Crimp type wire connector
The power transformer uses crimp type connectors
which connect the power cord and the primary side
of the transformer. When replacing the transformer,
follow these steps carefully and precisely to prevent
shock hazards.
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 a crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to the complete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC outlet.

Safety Check after Servicing
Examine the area surrounding the repaired location for
damage or deterioration. Observe that screws, parts,
and wires have been returned to their original positions. Afterwards, do the following tests and confirm
the specified values to verify compliance with safety
standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)
Table 1 : Ratings for selected area
AC Line VoltageClearance Distance (d), (d’)
220 to 240 V
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
≥3 mm(d)
≥6 mm(d’)
2. Leakage Current Test
Confirm the specified (or lower) leakage current
between B (earth ground, power cord plug prongs)
and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and
output terminals, microphone jacks, earphone jacks,
etc.) is lower than or equal to the specified value in the
table below.
Measuring Method (Power ON) :
Insert load Z between B (earth ground, power cord
plug prongs) and exposed accessible parts. Use an
AC voltmeter to measure across the terminals of load
Z. See Fig. 2 and the following table.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly grounded to remove any static electricity that may
be charged on the body.
2. Ground for Workbench
(1) Be sure to place a conductive sheet or copper plate
with proper grounding (1MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.

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.
Notes:
1. Do not use the part number shown on these drawings for ordering. The correct part number is shown
in the parts list, and may be slightly different or
amended since these drawings were prepared.
2. All resistance values are indicated in ohms
3
(K=10
3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in µF
(P=10
5. All voltages are DC voltages unless otherwise
specified.
6. Electrical parts such as capacitors, connectors,
diodes, IC’s, transistors, resistors, switches, and
fuses are identified by four digits. The first two digits are not shown for each component. In each
block of the diagram, there is a note such as shown
below to indicate these abbreviated two digits.

PAG ES :
1. CAUTION:
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE FUSE.
2. CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, first check to see that all components in the power supply circuit are not defective
before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the
power supply circuit to fail.
3. Note:
(1) Do not use the part number shown on the drawings for ordering. The correct part number is shown in the parts
list, and may be slightly different or amended since the drawings were prepared.
(2) To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.
4. Voltage indications for PLAY and REC modes on the schematics are as shown below:
< DVD Section >

CAUTION !
For continued protection against fire hazard,
replace only with the same type fuse.
NOTE :
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
CAUTION !
Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

Explanation of alignment for the tape to correctly run
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.
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
in Fig. M1 and continue turning the LDG Belt until
the Cassette Holder comes to the tape-loaded
position. Allow 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 procedure. 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.)

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.”

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 (FL6NS8) 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)
Note: Upon completion of the adjustment of Azimuth
Adj. Screw, 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.”
2. When the tape has been curled up or bent, turn the
alignment screw to adjust the height of REV Post.

1-E. Checking and Alignment of Tape
Path during reversing
Purpose:
To make sure that the tape path is well stabilized during reversing.
Symptom of Misalignment:
If the tape path is unstable during reversing, the tape
will be damaged.
Note: Do not use an Alignment Tape for this procedure. If the unit is not correctly aligned, the tape may
be damaged.
1. Insert a black cassette tape into the tray and set
the unit to REV. Then confirm if the tape has been
curled up or bent at the Take-up Guide Post[4] or
REV Post[5]. (Refer to Fig. M11 and M12.)

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.
