(See Fig-1).
1) The insulation resistance must be 3.5 to 6.0 MΩ
when applying
2) In the voltage withstand test, apply 1.0 KV for 1
minute and check that the GO lamp lights.
500V per second.
Insulation resistance: 3.5 to 6.0 MΩ (500 V/s)
Voltage-withstand: 1.0 KV for 1 minute
Safety checker (Model 7110, etc.)

Connect the earth cable
to the outside metal part
terminal.
*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.
!
Safety Components Symbol
This symbol is given to important parts which serve to maintain the safety of the product, and which
are made to confirm to special Safety Specifications.
Therefore, when replacing a component with this symbol make absolutely sure that you use a
designated part.

When repairing the Flat TV, never switch ON the main POWER with the degauss coil removed.
If the degauss coil must inevitably removed due to some reason, connect a dummy using either Method 1 or
Method 2 as described below.
Method 1: Prepare a replacement degauss coil and connect it during repair.
Method 2: Prepare a resistor of 2.8 ohm, 20 W. Manufacture a repair jig by connecting it to the degauss side
connector. Connect the jig during repair.
Waning
If the main POWER is switched ON without connecting degauss coil or dummy resistor, the cement resistor
R801 that is connected in parallel with the degauss coil burns to open.

2-1. Anode cap disassembly
2-1-1. Notice Before Disassembly
Discharge the anode.
1) The cathode-ray tube of this equipment has the structure
that the anode potential is automatically discharged
when the power is off. But immediately after the POWER
is turned off, there might be the case that the anode
potential has not been discharged completely. When
removing the Anode Cap, make sure to discharge the
anode potential.
Do not use a plier.
2) When using a plier to catch or loose the hook, the spring
is deteriorated depending on the gripping power of the
plier. Therefore, do not use a plier because the hook
may easily slip off from the CRT anode button and it will
be cause of accidents.
Do not rotate the Anode cap.
3) Do not rotate the Anode Cap. If the Anode Cap is
rotated, the hook may easily slip off.
2-1-2. Disassembly
Discharge the anode (See Fig-3).
1) Connect a flat-head screwdriver to the CRT GND using
a cable with clips.
2) Confirm that the electric current is conducted using the
tester at the tip of the screwdriver and the GND on the
TV side.
3) Put the tip of the screwdriver to the shutter hook.
Note) Take care not to scratch the Anode Cap.
4) Turn over the Anode Cap (See Fig-4).
Note) Take care not to damage the Anode Cap.

*When either FBT or anode cap is going to be replaced, be sure to replace both FBT and anode cap at the same time as
follows. (Because the anode cap cannot be removed any more if it is locked into the connector-type FBT.)
1. Remove the rubber cap at the tip end of the anode cap
assy.
2. Insert the terminal at the tip end of the high tension lead of the anode cap assy as far as it can go until you feel the clicking
feeling.
3. Pull the anode cap assy gently upward (with 2 to 3 kg) in order to confirm that the connector is firmly connected. Then move it
down again. (The reason of pulling gently is to confirm that the connector is firmly connected. If it is pulled too strongly, the
connector can be broken.)

ELECTRICAL ADJUSTMENT
Method of Using the Jig Remote Controller
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.
