CAUTIONS FOR SAFETY IN PERFORMING REPAIR

1-1 LASER BEAM SAFETY PRECAUTIONS

This DVD player uses a pickup that emits a laser beam.

Do not look directly at the laser beam coming
from the pickup or allow it to strike against your
skin.

The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep
your eyes at least 30cm away from the pickup lens when the diode is turned on. Do not look directly at the laser
beam.

CAUTION: Use of controls and adjustments, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.

1-2 IMPORTANT SAFETY PRECAUTIONS

1-2-1 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.

1-2-2 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.

1-2

1-2-3 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 Voltage Clearance Distance (d), (d’)

Chassis or Secondary Conductor

Primary Circuit Terminals

dd'

120 V

Note: This table is unofficial and for reference only.

Be sure to confirm the precise values.

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.

1-3-4 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.

c. The 1st pin of every male connector is indicated as

shown.

1-3-2 Instructions for Connectors

1. When you connect or disconnect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect
the AC cord.

2. FFC (Flexible Foil Connector) cable should be
inserted parallel into the connector, not at an angle.

About Optical Sensors

Caution:

An optical sensor system is used for the Tape Start
and End Sensors on this equipment. Carefully read
and follow the instructions below. Otherwise the unit
may operate erratically.

What to do for preparation

Insert a tape into the Deck Mechanism Assembly and
press the PLAY button. The tape will be loaded into
the Deck Mechanism Assembly. Make sure the power
is on, connect TP502 (S-INH) to GND. This will stop
the function of Tape Start Sensor, Tape End Sensor
and Reel Sensors. (If these TPs are connected before
plugging in the unit, the function of the sensors will
stay valid.) See Fig. 1.

Note: Because the Tape End Sensors are inactive, do
not run a tape all the way to the start or the end of the
tape to avoid tape damage.

4-4-1 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,

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.)

3. Check to see that the tape runs without creasing at
Take-up Guide Post [4] or without snaking between
Guide Roller [3] and ACE Head. (Fig. M3 and M5)

4. If creasing or snaking is apparent, adjust the Tilt
Adj. Screw of the ACE Head. (Fig. M6)

Purpose:

To obtain maximum PB FM envelope signal at the pre­set position of the Tracking Control Circuit, align the
Horizontal Position of the ACE Head.

Symptom of Misalignment:

If the Horizontal Position of the ACE Head is not prop­erly aligned, maximum PB FM envelope cannot be
obtained at the preset position of the Tracking Control
Circuit.

1. Connect the oscilloscope to TP301 (C-PB) and
TP513 (CTL) on the Main CBA. Use TP302 (RF­SW) as a trigger.

2. Playback the Gray Scale of the Alignment Tape
(MH-1) and confirm that the PB FM signal is
present.

3. Set the Tracking Control Circuit to the preset posi­tion by pressing “CH K” button and then “VCR­PLAY” button on the unit. (Refer to note on bottom
of page 4-7.)

4. Use the Flat Screwdriver so that the PB FM signal
at TP301 (C-PB) is maximum. (Fig. M6)

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.

Dropping envelope level at the beginning of track.

6. Set the Tracking Control Circuit to the preset posi-

tion by pressing “CH K” button and then “VCR­PLAY” button on the unit.

1-C. Checking/Adjustment of Envelope

Waveform

Purpose:

To achieve a satisfactory picture, adjust the PB FM
envelope becomes as flat as possible.

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 TP301 (C-PB) on the
Main CBA. Use TP302 (RF-SW) as a trigger.

2. Playback the Gray Scale on the Alignment Tape
(MH-1). Set the Tracking Control Circuit to the pre­set position by pressing “CH K” button and then
“VCR-PLAY” button on the unit. Adjust the height of
Guide Rollers [2] and [3] (Fig. M3, page 4-6) 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.

Fig. M8

Dropping envelope level at the end of track.

Fig. M9

Envelope is adjusted properly. (No envelope drop)

Fig. M10

Note: Upon completion of the adjustment of Guide

Rollers [2] and [3] (Refer to Fig. M3), check the X
Value by pushing the “CH K” or “CH L” buttons on the
unit alternately, to check the symmetry of the enve­lope. Check the number of pushes to ensure preset
position. The number of pushes “CH K” button on the
unit to achieve 1/2 level of envelope should match the
number of pushes “CH L” button on the unit from cen-
ter. If required, redo the “X Value Alignment.”

4-7

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 (MH-1) 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 K”
or “CH L” buttons on the unit alternately, to check the
symmetry of the envelope. Check the number of
pushes to ensure preset position. The number of
pushes “CH K” button on the unit to achieve 1/2 level
of envelope should match the number of pushes
“CH L” button on the unit 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. (Refer to Fig. M11 and M13.)

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 blank 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

5-3 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.

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.

ATTENTION: POUR UNE PROTECTION CONTINUE LES RISQES D'INCELE N'UTILISER QUE
DES FUSIBLE DE MEMO TYPE.
RISK OF FIRE-REPLACE FUSE AS MARKED.

This symbol means fast operating fuse.
Ce symbole represente un fusible a fusion rapide.

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:

NOTE:

The voltage for parts in hot circuit is measured using
hot GND as a common terminal.

Because a hot chassis ground is present in the power
supply circut, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly, when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
