SERVICING NOTICES ON CHECKING

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 cathode­ray 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-RAY1. KEEP THE NOTICES

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 cathode­ray 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

Earphone jack

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.)

Location of Anode Cap

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.)

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.

1-A.

3.

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
10(+2, -0)mm.

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

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.

BEFORE MAKING ELECTRICAL
ADJUSTMENTS

Read and perform these adjustments when repairing the
circuits or replacing electrical parts or PCB assemblies.

CAUTION

•

Use an isolation transformer when performing any
service on this chassis.

•

Before removing the anode cap, discharge electricity
because it contains high voltage.

•

When removing a PCB or related component, after
unfastening or changing a wire, be sure to put the wire
back in its original position.
Inferior silicon grease can damage IC's and transistors.

•

When replacing IC's and transistors, use only specified
silicon grease.
Remove all old silicon before applying new silicon.
