SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES3. PUT PARTS AND WIRES IN THE
As for the places which need special attentions,
they are indicated with the labels or seals on the
cabinet, chassis and parts. Make sure to keep the
indications and notices in the operation manual.
2. USE THE DESIGNATED PARTS
The parts in this equipment have the specific
characters of incombustibility and withstand
voltage for safety. Therefore, the part which is
replaced should be used the part which has
the same character.
Especially as to the important parts for safety
which is indicated in the circuit diagram or the
table of parts as a mark, the designated
parts must be used.
ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.
PERFORM A SAFETY CHECK AFTER
4.
SERVICING
Confirm that the screws, parts and wiring which
were removed in order to service are put in the
original positions, or whether there are the
portions which are deteriorated around the
serviced places serviced or not. Check the
insulation between the antenna terminal or
external metal and the AC cord plug blades.
And be sure the safety of that.
HOW TO ORDER PARTS
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER.
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be

WHEN REPLACING DVD DECK
[ When the removal of the DVD Deck ]
Before removing Pick Up PCB and DVD PCB connector, make the short circuit on the position as
shown Fig. 1 using a soldering. If you remove the DVD Deck with no soldering, the Laser may be
damaged.
[ When the installation of the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
PCB connector.
NOTE
Use the Pb Free solder and the exclusive soldering iron.
•
Manual soldering conditions
•
• Soldering temperature: 320 ± 20˚C
• Soldering time: Within 3 seconds
• Soldering combination: Sn-3.0Ag-0.5Cu
When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the
•
Flux smoke from it.

PREPARATION OF SERVICING
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is
received at the time of repair, a life of product may become short.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode enough at the time of repair, and work.
• It works on the desk which performed measures against static electricity, such as conductive
mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.

REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
REMOVAL
Put the Masking Tape (cotton tape) around the Flat
1.
Package IC to protect other parts from any damage.
(Refer to Fig. 4-1.)
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.
When IC starts moving back and forth easily after
3.
desoldering completely, pickup the corner of the IC using
a tweezers and remove the IC by moving with the IC
desoldering machine. (Refer to Fig. 4-3.)
NOTE
Some ICs on the PCB are affixed with glue, so be
careful not to break or damage the foil of each IC
leads or solder lands under the IC when removing it.

new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.
(Refer to Fig. 4-5.)
Soldering Iron
Solder temporarily
Supply the solder from the upper position of IC leads

Solder temporarily
sliding to the lower position of the IC leads.
(Refer to Fig. 4-6.)

When bridge-soldering between terminals and/or the
4.
soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 4-8.)

Finally, confirm the soldering status on four sides of the
5.
IC using a magnifying glass.
Confirm that no abnormality is found on the soldering
position and installation position of the parts around the
IC. If some abnormality is found, correct by resoldering.
NOTE
When the IC leads are bent during soldering and/or
repairing, do not repair the bending of leads. If the
bending of leads are repaired, the pattern may be
damaged. So, be always sure to replace the IC in this
case.

CLEANING
NOTE
After cleaning the heads with isopropyl alcohol, do not
run a tape until the heads dry completely. If the heads
are not completely dry and alcohol gets on the tape,
damage may occur.
1. AUDIO CONTROL HEAD
Clean the Audio Control Head with the cotton stick
soaked by alcohol. Clean the full erase head in the
same manner. (Refer to the figure below.)
Audio Control Head
2. TAPE RUNNING SYSTEM
When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.
3. CYLINDER
Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol. Hold it to the cylinder head softly.
Turn the cylinder head counterclockwise to clean it (in
the direction of the arrow). (Refer to the figure below.)
NOTE
Do not exert force against the cylinder head. Do not move
the chamois upward or downward on the head.
Use the chamois one by one.

While turning the reel and confirm the following points.
Check if the surface “A” of reel disk is lower than the
surface “B” of reel disk height adjustment jig (JG024A)
and is higher than the surface “C”. If it is not passed,
place the height adjustment washers and adjust to

2. CONFIRMATION AND ADJUSTMENT
OF TAPE RUNNING MECHANISM
Tape Running Mechanism is adjusted precisely at the
factory. Adjustment is not necessary as usual. When you
replace the parts of the tape running mechanism because
of long term usage or failure, the confirmation and adjustment are necessary.
2-1: GUIDE ROLLER
1.
Playback the VHS Alignment Tape (JG001 or JG001B).
(Refer to SERVICING FIXTURE AND TOOLS)
2.
Connect CH-1 of the oscilloscope to TP101 (Envelope)
and CH-2 to TP3002 (SW Pulse).
3.
Press and hold the ATR button on the remote control
more than 2 seconds to set tracking to center.
4.
Trigger with SW Pulse and observe the envelope. (Refer
to Fig. 2-1-A)
5.
When observing the envelope, adjust the Adjusting
Driver (JG005) slightly until the envelope will be flat.
Even if you press the Tracking Button, adjust so that
flatness is not moved so much.
6.
Adjust so that the A : B ratio is better than 3 : 2 as shown
in Fig. 2-1-B, even if you press the Tracking Button to
move the envelope (The envelope waveform will begin to
decrease when you press the Tracking Button).
7.
Adjust the PG shifter during playback.
(Refer to the ELECTRICAL ADJUSTMENTS)
NOTE
After adjustment, confirm and adjust A/C head.

2-2: CONFIRMATION AND ADJUSTMENT OF AUDIO/
CONTROL HEAD
When the Tape Running Mechanism does not work well,
adjust the following items.
1.
Playback the VHS Alignment Tape (JG001 or JG001B).
(Refer to SERVICING FIXTURE AND TOOLS)
2.
Confirm that the reflected picture of stamp mark is
appeared on the tape prior to P4 Post as shown in Fig. 2-
2-A.
a)
When the reflected picture is distorted, turn the screw
1 clockwise until the distortion is disappeared.
b)
When the reflected picture is not distorted, turn the
screw 1 counterclockwise until little distortion is
appeared, then adjust the a).
3.
Turn the screw 2 to set the audio level to maximum.
4.
Confirm that the bottom of the Audio/ Control Head and
the bottom of the tape is shown in Fig. 2-2-C.
c)
When the height is not correct, turn the screw 3 to
adjust the height. Then, adjust the 1~3 again.

2-3: TAPE RUNNING ADJUSTMENT
(X V ALUE ADJUSTMENT)
1.
Confirm and adjust the height of the Reel Disk.
(Refer to item 1-1)
2.
Confirm and adjust the position of the Tension Post.
(Refer to item 1-2)
3.
Adjust the Guide Roller. (Refer to item 2-1)
4.
Confirm and adjust the Audio/Control Head.

Playback the VHS Alignment Tape (JG001S or JG001T).
(Refer to SERVICING FIXTURE AND TOOLS)
7.
Press and hold the ATR button on the remote control
more than 2 seconds to set tracking to center.
8.
Set the X Value adjustment driver (JG153) to the 4 of
Fig. 2-2-B. Adjust X value so that the envelope waveform
output becomes maximum. Check if the relation between
Audio and Envelope waveform becomes (1) or (2) of Fig.
