IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteristics which are often not evi-
dent 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 iden-
tified by a # on schematics and in parts lists. Use of a
substitute replacement that does not have the same
safety characteristics as the recommended replace-
ment part might create shock, fire, and/or other haz-
ards. The Product’s Safety is under review
continuously and new instructions are issued when-
ever 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 impor-
tant 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 block-
ing 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 solder-
ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fus-
ible 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 clo-
sure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC outlet.
![](asset-5.png)
1-2-2 H9622SFTY
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 posi-
tions. 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 sol-
dered terminals, and between terminals and surround-
ing metallic parts. (See Fig. 1)
Table 1: Ratings for selected area
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 termi-
nals, 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.
AC Line Voltage Clearance Distance (d), (d’)
120 V ≥ 3.2mm (0.126 inches)

How to Remove / Install Flat Pack-IC
1. Removal
With Hot-Air Flat Pack-IC Desoldering Machine:.
(1) Prepare the hot-air flat pack-IC desoldering
machine, then apply hot air to the Flat Pack-IC
(about 5 to 6 seconds). (Fig. S-1-1)
(2) Remove the flat pack-IC with tweezers while apply-
ing the hot air.
(3) Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(4) Release the flat pack-IC from the CBA using twee-
zers. (Fig. S-1-6)
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
Pack-IC.
2. Do not supply hot air to the chip parts around the
flat pack-IC for over 6 seconds because damage to
the chip parts may occur. Put masking tape around
the flat pack-IC to protect other parts from damage.

1-3-2 NOTE_1
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 the solder lands under the IC when removing
it.
With Soldering Iron:
(1) 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)
(2) 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)
(3) Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(4) Release the flat pack-IC from the CBA using twee-
zers. (Fig. S-1-6)
With Iron Wire:
(1) 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)
(2) Affix the wire to a workbench or solid mounting
point, as shown in Fig. S-1-5.
(3) While heating the pins using a fine tip soldering
iron or hot air blower, pull up the wire as the solder
melts so as to lift the IC leads from the CBA contact
pads as shown in Fig. S-1-5

up. Then remove (glue will be melted). (Fig. S-1-6)
(5) Release the flat pack-IC from the CBA using twee-
zers. (Fig. S-1-6)
Note:
When using a soldering iron, care must be taken
to ensure that the flat pack-IC is not being held by
glue. When the flat pack-IC is removed from the
CBA, handle it gently because it may be damaged
if force is applied.
2. Installation
(1) 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.
(2) The “ I ” mark on the flat pack-IC indicates pin 1.
(See Fig. S-1-7.) Be sure this mark matches the 1
on the PCB when positioning for installation. Then
presolder the four corners of the flat pack-IC. (See
Fig. S-1-8.)
(3) Solder all pins of the flat pack-IC. Be sure that none
of the pins have solder bridges.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electro-
static charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is prop-
erly grounded to remove any static electricity that may
be charged on the body.
2. Ground for Workbench
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 cloth-
ing will not escape through the body grounding band,
be careful to avoid contacting semi-conductors with
your clothing.

CAUTION 1: Locking Tabs (L-1) and (L-2) are fragile.
Be careful not to break them.
1-1. Release three Locking Tabs (L-1).
1-2. Release three Locking Tabs (L-2), then remove
the Front Assembly.
CAUTION 2: Electrostatic breakdown of the laser
diode in the optical system block may occur as a
potential difference caused by electrostatic charge
accumulated on cloth, human body etc, during
unpacking or repair work.
To avoid damage of pickup follow next procedures.
2-1. Disconnect Connector (CN301). Remove a
Screw (S-6) and lift the DVD Main CBA Unit. (Fig.
D4)
2-2. Short the three short lands of FPC cable with sol-
der before removing the FFC cable (CN201) from
it. If you disconnect the FFC cable (CN201), the
laser diode of pickup will be destroyed. (Fig. D4)
CAUTION 3: When reassembling, confirm the FFC
cable (CN201) is connected completely. Then remove
the solder from the three short lands of FPC cable.
(Fig. D4)

ELECTRICAL ADJUSTMENT INSTRUCTIONS
General Note: "CBA" is an abbreviation for
"Circuit Board Assembly."
NOTE:
1.Electrical adjustments are required after replacing
circuit components and certain mechanical parts.
It is important to do these adjustments only after
all repairs and replacements have been com-
pleted. Also, do not attempt these adjustments
unless the proper equipment is available.
2.To perform these alignment / confirmation proce-
dures, make sure that the tracking control is set in
the center position: Press either "CHANNEL L5??" or
"CHANNEL K" button on the front panel first, then
the "PLAY" button on the front panel.
Test Equipment Required
1.Oscilloscope: Dual-trace with 10:1 probe,
V-Range: 0.001~50V/Div.,
F-Range: DC~AC-20MHz
2.Alignment Tape (VFMS0001H6)
Head Switching Position Adjust-
ment
Purpose:
To determine the Head Switching position during
playback.
Symptom of Misadjustment:
May cause Head Switching noise or vertical jitter
in the picture.
Reference Notes:
Playback the Alignment tape and adjust VR501 so that
the V-sync front edge of the CH1 video output wave-
form is at the 6.5H±1H (412.7µs±63.5µs) delayed
position from the rising edge of the CH2 head switch-
ing pulse waveform.

Standard Notes
WARNING
Critical components having special safety characteris-
tics are identified with a # by the Ref. No. in the parts
list and enclosed within a broken line (where several
critical components are grouped in one area) along
with the safety symbol # on the schematics or
exploded views.
Use of substitute replacement parts which do not have
the same specified safety characteristics may create
shock, fire or other hazards.
Under no circumstances should the original design be
modified or altered without written permission from
Philips Consumer Electronics Company. Philips
assumes no liability, express or implied, arising out of
any unauthorized modification of design. Servicer
assumes all liability.
* Broken Line :
Capacitor Temperature Markings
Capacitors and transistors are represented by the fol-
lowing symbols.
Notes:
1. Do not use the part number shown on these draw-
ings 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. 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.
3. How to read converged lines.
Examples:
(1). "1-D3" means that line number "1" goes to area
"D3."
(2). "1-B1" means that line number "1" goes to area
"B1."
4. All resistance values are indicated in ohms
(K=103, M=106).
5. Resistor wattages are 1/4W or 1/6W unless other-
wise specified.
6. All capacitance values are indicated in µF
(P=10-6 µF).
7. All voltages are DC voltages unless otherwise
specified.
8. Voltage indications PLAY and REC modes on the
schematics are as shown below.

MECHANICAL ALIGNMENT PROCEDURES
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 prepara-
tions 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 con-
tinuously, 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 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 sur-
face. (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)
1-B. X Value Alignment
Purpose:
To obtain maximum PB FM envelope signal at the pre-
set 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 prop-
erly 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 (RF-
SW) as a trigger.
2. Playback the Gray Scale of the Alignment Tape
(VFMS0001H6) and confirm that the PB FM signal
is present.
3. Set the Tracking Control Circuit to the preset posi-
tion by pressing CH UP button on the remote con-
trol unit then “PLAY” button on the unit. (Refer to
note on bottom of page 2-3-4.)
4. Use the Flat Screwdriver so that the PB FM signal
at TP301 (C-PB) is maximum. (Fig. M6)

5. To shift the CTL waveform, press CH UP or CH
DOWN button on the remote control unit. Then
make sure that the maximum output position of PB
FM envelope signal become within ±2ms from pre-
set position.
6. Set the Tracking Control Circuit to the preset posi-
tion by pressing CH UP button on the remote con-
trol unit. and then “PLAY” button.
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 varia-
tion 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
(VFMS0001H6). Set the Tracking Control Circuit to
the preset 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 enve-
lope becomes as flat as possible. To do this adjust-
ment, 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 alter-
nately, 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 (VFMS0001H6) and
confirm that the audio signal output level is 6kHz.
3. Adjust Azimuth Adj. Screw so that the output level
on the AC Voltmeter or the waveform on the oscillo-
scope 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.”
1-E. Checking and Alignment of Tape
Path during reversing
Purpose:
To make sure that the tape path is well stabilized dur-
ing 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 proce-
dure. 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.)
2. When the tape has been curled up or bent, turn the
alignment screw to adjust the height of REV Post.

ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape load-
ing/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 individ-
ual gears and levers be maintained.
All alignments are to be performed with the mech-
anism 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.
Alignment points in Eject Position
Alignment 1
Loading Arm (SP) and (TU) Assembly
Install Loading Arm (SP) and (TU) Assembly so
that their triangle marks point to each other as
shown in Fig. AL2.
Alignment 2
Mode Gear
Keeping the two triangles pointing at each other,
install the Loading Arm (SP) Assembly so that the
last tooth of the gear meets the most inside teeth
of the Mode Gear. See Fig. AL2.
Alignment 3
Cam Gear (A), Rack Assembly
Install the Rack Assembly so that the first tooth on
the gear of the Rack Assembly meets the first
groove on the Cam Gear (A) as shown in Fig. AL3.
