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

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.

DISASSEMBLY INSTRUCTIONS
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
Fig. 3-3
NOTE
Confirm that there is no dirt, dust, etc. at the spot where
the cap was located.
2.3.Arrange the wire of the Anode Cap and make sure the
wire is not twisted.
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.

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)
1,500
hours
2,000
hours
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 up or down since this can damage the head.
Always use a piece of chamois for cleaning.
3,000
hours
Notes
Clean those parts in
contact with the tape.
Clean the rubber, and
parts which the rubber
touches.
Replace when rolling
becomes abnormal.
Clean the Head.

2. TAPE RUNNING CONFIRMATION
AND ADJUSTMENT
••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.
2-1: GUIDE ROLLER
1.
Connect CH-1 on the oscilloscope to TP4002 (PB Envelope)
and CH-2 to TP4001 (SW Pulse).
2.
Set the tracking to manual center position in the following
way. Press and hold the tracking auto button more than 2
seconds to set the tracking to center position.
3.
Trigger with SW pulse and observe the envelope.
(Refer to Fig. 2-1-A)
4.
Adjust the guide roller height while observing the envelope,
and make the envelope flat. Adjust the envelope so that
the flatness will not be affected even when the tracking
control button is pressed. (Use the adjustment screwdriver
JG005).
5.
Press and hold the tracking control button and (at the point
that the envelope waveform starts to reduce) adjust the
envelope so that the A : B ratio is better than 3 : 2.
(Refer to Fig. 2-1-B)
6.
Adjust the PG shifter (ELECTRICAL ADJUSTMENTS :

When the tape is running abnormally, perform the
following adjustments.
1.
Insert a new tape and play it back.
2.
Confirm that there is no crease on the tape between the P4
post and guide roller (R) and the tape is running smoothly.
(It is absolutely impossible to get satisfactory sound if the
tape is distorted between the A/C head and P4 post.)
3.
If the tape still does not run smoothly, turn the screw 1 and
adjust the tilt of the A/C head. (Refer to Fig. 2-2)

(Refer to No. 2 of the item 2-1).
2-3: ADJUSTMENT OF A/C HEAD HEIGHT AND
AZIMUTH
1.
Playback a VHS alignment tape (JG001C) and observe
the waveform at the audio output terminal.
2.
Turn the screw 2 slowly to change the azimuth of the A/C
head. Adjust the height so that the audio output becomes
maximum. (Refer to Fig. 2-2)
3.
Adjust the screw 3, (Refer to Fig. 2-2) until the height of
the A/C head reaches the position against the tape as
shown in Fig. 2-3.
4.
When the control head height is not correct. (When you
must turn the screw more than 45 degrees), Turn all of the
screws 1, 2 and 3 to the same degrees.
Then confirm the angle of the audio/control head and
adjust again.

Note: Some parts labeled # are not compatible, but they are very similar before servicing,
be sure to check the parts in the INFORMATION FOR USING THE DECK PARTS (OVD-5): 09-986-269-20O
for the repair. Because if you use wrong parts, the deck or tape will be damaged.
