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.)

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

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.

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.

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.

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.

1. ADJUSTMENT PROCEDURE

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

CAUTION

When replacing IC's or transistors, use only specified
silicon grease (G746).
(To prevent the damage to IC's and transistors.)

On-Screen Display Adjustment

1.

Unplug the AC plug for more than 30 minutes to set the
clock to the non-setting state. (To release the Back-Up
immediately, take the short circuit between C1003 and
GND at the Power Off.) Then, set the volume level to
minimum.

2.

Press the VOL. DOWN button on the set and the
channel button (9) on the remote control for more than
2 seconds to display adjustment mode on the screen
