NOTICES BEFORE REPAIRING
To make the best use of this equipment, make sure to
obey the following items when repairing (or mending).
1. Do not damage or melt the tunicate of the leading
wire on the AC1 side, including the power supply
cord.
2. Do not soil or stain the letters on the spec.
inscription plates, notice labels, fuse labels, etc.
3. When repairing the part extracted from the
conducted side of the board pattern, fix it firmly
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 M
when applying 500V per second.
2) In the voltage withstand test, apply 3 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.

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 servicing and checking on the TV, note the followings.
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.
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
