with applying bond to the pattern and the part.
4. Restore the following items after repairing.
1) Conditions of soldering of the wires (especially,
the distance on the AC1 side).
2) Conditions of wiring, bundling of wires, etc.
3) Types of the wries.
4) Attachment conditions of all types of the insulation.
5. After repairing, always measure the insulation
resistance and perform the voltage-withstand test
(See Fig-1).
1) The insulation resistance must be 7.0 to 9.5 MΩ
when applying
2) In the voltage withstand test, apply 1.5 KV for 1
minute and check that the GO lamp lights.

*Breaking current set to 10 mA.
*Connect the safety checker as shown in Fig-1,
then measure the resistance and perform the test.
* Do not touch the equipment during testing.
*For details of the safety checker, refer to the supplied
Operation manual.
When servicing and checking on the TV, note the followings.
1. Keep the notices.
As for the places which need special attentions, they
are indicated with 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
characteristics of incombustibility and withstand
voltage for safety.
Therefore, use a part which has the same character
as the replaced part. Especially as to the important
parts for safety which is indicated in the circuit
diagram or the table of parts with 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 so that these parts do not make contact
with the printed board. The inside wiring is designed
!
not to get close to the pyrogenic parts and high
voltage parts. Therefore, put these parts in the
original positions.
5. Take care of the cathode-ray tube.
By setting an explosion-proof cathode-ray tube in this
equipment, safety is secured against implosion.
However, when removing it or servicing from the
back, it gives out shock that is dangerous. Take
enough care to deal with it.
6. Avoid an X-ray.
Safety is secured against an X-ray by giving
considerations to the cathode-ray tube and the high
voltage peripheral circuit, etc. Therefore, when
repairing the high voltage peripheral circuit, use the
designated parts and do not change the circuit.
Repairing, except indicates, causes rising of high
voltage, and the cathode-ray tube emits an X-ray.
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 deteriorated portions
around the places serviced.

Most of the video circuit and the deflection circuit of this set can be adjusted by using the jig remote controller.
Jig remote controller: RC-AVC01
The jig remote controller RC-AVC01 has the two operating modes. One is the NORMAL mode and the other is the TEST mode.
Either the NORMAL mode or the TEST mode can be selected by short-circuiting or opening the shorting land of the printed foil
pattern.
The TEST mode of the jig remote controller is used for adjusting this set.
The NORMAL mode and the TEST mode are selected as described below.
NORMAL/TEST mode selection method:
Disassemble the jig remote controller and locate the shorting land J1 and J2 on the foil pattern of the printed circuit board.
NORMAL mode:
J1 Shorted
J2 Open
TEST mode:
J1 Open
J2 Shorted
When the remote controller enters the TEST mode, its REPEAT key becomes the TEST key and the CAPTION key becomes the
FINISH key. All keys other than the above two keys are disabled so that the remote controller will not operate even if any key other
than those two keys is pressed.
When the word the TEST key or the FINISH key is written in this Service Manual, it means that the REPEAT key must be
pressed instead of the TEST key, and the CAPTION key must be pressed instead of the FINISH key respectively on the
actual jig remote controller.
