SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
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. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an electric
shock while the electric current is flowing.
3. 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.
4. PUT PARTS AND WIRES IN THE 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.
5. TAKE CARE TO DEAL WITH THE
CATHODE-RAY TUBE
In the condition that an explosion-proof cathode-ray
tube is set in this equipment, safety is secured against
implosion. However, when removing it or serving from
backward, it is dangerous to give a shock. Take
enough care to deal with it.
6. AVOID AN X-RAY
Safety is secured against an X-ray by considering about
the cathode-ray tube and the high voltage
peripheral circuit, etc.
Therefore, when repairing the high voltage peripheral
circuit, use the designated parts and make sure not
modify the circuit.
Repairing except indicates causes rising of high
voltage, and it emits an X-ray from the cathode-ray tube.
PERFORM A SAFETY CHECK AFTER
7.
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.
(INSULATION CHECK PROCEDURE)
1.
Unplug the plug from the AC outlet.
2.
Remove the antenna terminal on TV and turn on the
TV.
3.
Insulation resistance between the cord plug terminals
and the eternal exposure metal [Note 2] should be
more than 1M ohm by using the 500V insulation resistance meter [Note 1].
4.
If the insulation resistance is less than 1M ohm, the
inspection repair should be required.
[Note 1]
If you have not the 500V insulation resistance meter,
use a Tester.
[Note 2]
External exposure metal: Antenna terminal

3. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work.
*
After turning the power off there might still be a potential
voltage that is very dangerous. When removing the
Anode Cap, make sure to discharge the Anode Cap's
potential voltage.
*
Do not use pliers to loosen or tighten the Anode Cap
terminal, this may cause the spring to be damaged.
REMOVAL
1. Follow the steps as follows to discharge the Anode Cap.
(Refer to Fig. 3-1.)
Connect one end of an Alligator Clip to the metal part of a
flat-blade screwdriver and the other end to ground.
While holding the plastic part of the insulated Screwdriver,
touch the support of the Anode with the tip of the
Screwdriver.
A cracking noise will be heard as the voltage is discharged.
GND on the CRT
3. After one side is removed, pull in the opposite direction to
remove the other.
NOTE
Take care not to damage the Rubber Cap.
INSTALLATION
1. Clean the spot where the cap was located with a small
amount of alcohol. (Refer to Fig. 3-3.)

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
Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol and clean the audio control head by
wiping it horizontally. Clean the full erase head in the
same manner. (Refer to the figure below.)
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.

NOTE FOR THE REPLACING OF MEMORY IC
If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken to
ensure correct data settings while making reference to TABLE 1.
NOTES:
•
Initial Data setting will not be possible if clock has been set. To reset clock, either unplug AC cord and allow
at least 30 minutes before Power On or alternatively, discharge backup capacitor.

MECHANICAL ADJUSTMENTS
1. CONFIRMATION AND ADJUSTMENT
Read the following NOTES before starting work.
••Place an object which weighs between 450g~500g on
the Cassette Tape to keep it steady when you want to
make the tape run without the Cassette Holder. (Do not
place an object which weighs over 500g.)
When you activate the deck without the Cassette Holder,
short circuit between TP1001 and GND. (Refer to
ELECTRICAL ADJUSTMENT PARTS LOCATION
GUIDE) In this condition the BOT/EOT/Reel Sensor will
not function.
CONFIRMATION AND ADJUSTMENT OF REEL
1-1:
DISK HEIGHT
1.
Turn on the power and set to the STOP mode.
2.
Set the master plane (JG022) and reel disk height
adjustment jig (JG024A) on the mechanism framework,
taking care not to scratch the drum, as shown in Fig. 1-
1-A.
3.
Confirm that "A" of the reel disk is lower than "B" of the
reel disk height adjustment jig (JG024A), and is higher
than "C". If it is not enough height, adjust to 10(+0.2, -0)
mm with the height adjustment washer.
4.
Adjust the other reel in the same way.

POST POSITION
1.
Set to the PLAY mode.
2.
Adjust the Tension Adjust until the edge of the Tension
Arm is positioning within 0.5mm range from the
standard line center of Main Chassis.
After this adjustment, confirm that the cut position is
located in "A" area as shown in Fig. 1-2-B. If it is
located in "B" area, adjust again.
3.
While turning the S Reel clockwise, confirm that the
edge of the Tension Arm is located in the position
described above.
