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.
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.
2. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an electric
shock while the electric current is flowing.
7. PERFORM A SAFETY CHECK AFTER
SERVICING
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.
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.
4. PUT PARTS AND WIRES IN THE ORIGINAL
POSITION AFTER ASSEMBLING OR WIRING
(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.
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
[Note 1]
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.
If you have not the 500V insulation resistance meter,
use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone jack

VCR TEST TAPE INTERCHANGEABILITY TABLE
There are two types of the new alignment tape CH-1B (for NTSC) and CH-2 (for PAL). On each tape four signals (1) - (4) are
recorded for the times and in the order shown below.
(1) : 8min. ---> (2) : 2min. ---> (3) : 5min. ---> (4) : 5min.
The TTV-MP1 (for M-PAL), TTV-MS1 (for MESECAM) and TTV-S1 (for SECAM) alignment tapes have the same contents as
the previous tapes.

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.)

PREVENTIVE CHECKS AND SERVICE INTERVALS
The following standard table depends on environmental conditions and usage. Unless maintenance is properly
carried out, the following service intervals may be quite shortened as harmful effects may be had on other parts.
Also, long term storage or misuse may cause transformation and aging of rubber parts.

NOTE
3. CYLINDER
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.
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
NOTE
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)
Do not exert force against the cylinder head. Do not move
the chamois up or down since this can damage the head.
Always use a piece of chamois for cleaning.

2. TAPE RUNNING SYSTEM
When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.

Read the following NOTED items before starting work.
1. Turn on the power and set to the PLAY mode adjust the
Tension so that the Tension Post is at the position of
0.3mm~0.5mm from the Rib. (Refer to Fig. 1-2)
2. Confirm that the video tape is not curling at the flange of
P1 post or is not running on flanges.
• Place an object which weighs between 350g and 500g on
the Cassette Tape to keep it steady when you want to
make the tape run without the Front Loading Unit 15. (Do
not place an object which weighs over 500g.)
• When you activate the deck without the Front Loading
Unit 15, short circuit between TP1001 and Ground. In
this condition the BOT/EOT/Reel Sensor will not function.

• Tape running is adjusted precisely at the factory.
Normally, it is not necessary to make adjustments.
It is necessary to confirm and make adjustments
when the parts of the tape running mechanism are
replaced because of extensive usage or failure.
• When adjusting P2, P3 and Value X, be careful to the
Primary side of Main PCB on the Video Block for a electric
shock. So, use a insulator material such as plastic for JIG
driver grip.
NOTE
After setting the torque gauge on the reel disk, hold the
gauge in place.
Push the REWIND button and the reel disk will begin to
turn.
1-6: CONFIRMATION OF REEL BRAKE TORQUE
