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
2) In the voltage withstand test, apply 3.0 KV for 1
minute and check that the GO lamp lights.
500V per second.
Insulation resistance: 7.0 to 9.5 M (500 V/s)
Voltage-withstand: 3.0 KV for 1 minute
Safety checker (Model 7110, etc.)
Earth cable
AC cable
Fig-1
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 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 so that these parts 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 of the cathode-ray tube.
By setting 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 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 the portions which are
deteriorated around the places serviced.

Important recommendations
1.1Before beginning the adjustments, the TV set should be a pre-heated during at least 15
minutes.
1.2The positioning of the TV set should obey the magnetic parameters of South Amer ica that
it is -120 vertical mG. In the practice, this is gotten with a relative precision, positioning the
TV set with the face (screen) of the CRT pointing to the geographical East.

Note:
It is necessary to pre-heat the TV during 15 minutes, before its calibration.

Register 24 (OP4):
This register has CC line number - (Low nibble to 60Hz and high nibble to 50Hz)
The Bits 0,1,2,3 are used to select the line where Closed Caption information will be extracted when in
60Hz, and the bits 4, 5, 6, 7 are used to select the line where Closed Caption information will be extracted
when in 50Hz
Note:
This information is used by microcontroller.

3.Geometry of the Image
a) Using the PM - 5515 generator, apply the crosshatch pattern with circle.
b) Adjust the following items:
Vertical slope (VSl);
Height (VAm);
Vertical position (VSh);
Center Linearity (VSc);
Horizontal position (HSh)
Adjust the above items, until obtaining the best circle symmetry and positioning, as well as the
minor image geometric distortion.

4.White balance
Note:
The cut point doesn’t need adjustment, because it’s automatically made by the
IC501.
The white adjustment is already pre-adjusted and incised in the IC501 and,
thus, its adjustment is not necessary.
Otherwise, if it is necessary to change the temperature of the white pattern, proceed in the following way:
a) Enter in the service mode.
b) Select via CH
c) Increase or decrease the function via VOL
