SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
6. AVOID AN X-RAY
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
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.
7. PERFORM A SAFETY CHECK AFTER
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)
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
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
[Note1] .
4. If the insulation resistance is less than 1M
ohm, the inspection repair should be
required.
[Note 1]
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.
If you have not the 500V insulation
resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone Jack

3. After one side is removed, pull in the opposite direction to
remove the other.
3. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work.
*
*
NOTE
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.
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.)
REMOVAL
Location of Anode Cap
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.
Fig. 3-3
GND on the CRT
NOTE
Confirm that there is no dirt, dust, etc. at the spot where
the cap was located.
2. Arrange the wire of the Anode Cap and make sure the
wire is not twisted.
3. Turn over the Rubber Cap. (Refer to Fig. 3-4.)

NOTE
2. TAPE RUNNING SYSTEM
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.
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.)
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.)
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.

PREPARATION FOR SERVICING
How to use the Servicing Fixture
1. Unplug the connector CP757 and CP353, then remove the TV/VCR Block from the set.
2. Remove the Operation PCB from the set, then connect it with the Syscon PCB.
If necessary, connect CP353. (Front A/V Jack Input Terminal)
3. Short circuit between TP1001 and Ground with the cable JG154.
(Refer to MAJOR COMPONENTS LOCATION GUIDE)
4. The EOT, BOT and Reel Sensor do not work at this moment.
At that time, the STOP/EJECT button is available to insert and eject the Cassette Tape.

POST POSITION
1. CONFIRMATION AND ADJUSTMENT
Read the following NOTES before starting work.
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.
• 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.
1-1: CONFIRMATION AND ADJUSTMENT OF REEL
DISK HEIGHT
Standard line of Main Chassis
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. 11-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.
