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 MΩ
when applying 500V per second.
2) In the voltage withstand test, apply 1.0 kV for 1
minute and check that the GO lamp lights.
Insulation resistance: 7.0 to 9.5 MΩ (500 V/s)
Voltage-withstand: 1.0 kV for 1 minute.

AC cable
Connect the earth cable
to the outside metal part
terminal.
Fig-1
* 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.

2. HIGH-VOLTAGE CAP (ANODE CAP) REMOVAL
Figure 1-1
2-1. Cautions before Removing
Discharge the anode voltage
(1) The anode voltage is not discharged completely from the
CRT of this unit even after the power is turned off. Be
sure to discharge the residual anode voltage before
removing the anode cap.
Do not use pliers
(2) Do not use pliers, etc. to remove the anode cap. If you
used pliers and bent the hook to remove the cap, the spring
characteristics of the hook could be lost, and when
reinstalled, the cap would come off from the CRT anode
button easily, causing an accident.
Do not turn the anode cap
(3) If the anode cap is turned in the direction of its
circumference, the hook is likely to come off.
2-2. Anode Cap Removal
Discharge the anode voltage. (See Figure 2-1)
(1) Connect a flat-bladed screwdriver to the CRT GND via
an alligator clip.

Because the video signal output from a pattern generator is used as
the adjustment signal input during adjustment, the video signal
output from the pattern generator must conform with the
specifications. Measure the output waveform across 75 Ω load.
Confirm that the synchronizing signal has an amplitude of about
0.3 V, the video signal portion has an amplitude of about 0.7 V and
the burst signal has an amplitude of about 0.3 V with flat envelope.
Confirm that ratio of the burst signal amplitude and the red signal
amplitude is 0.30 : 0.66. If the output signal does not conform with
the specifications, calibrate the pattern generator. (Refer to pattern
generator operation manual.)
Use the LEADER: LCG 404 for the pattern generator.
1. CRT ADJUSTMENT
1-1. Precautions
(1) Receive the white raster signal, and then perform aging for at
least 20 minutes.
(2) Demagnetize the area surronding the CRT with a degausser
before making adjustments.
(3) Set the picture quality for each mode to the factory setting.
(4) Position the front screen facing the east as much as possible.
1-2. Purpose
(1) Beam landing adjustment (purity magnet)
Set the left/right balance of beam landing. If there is a
discrepancy in this adjustment, a color irregularity will occur.
After completion of the landing adjustment, it is necessary to
perform convergence adjustment.

completing the landing adjustments, be sure to carry out
convergence adjustments.
If the color irregularities in the screen’s corner section are
not improved, correct them with the landing magnet. After
using the landing magnet, be sure to demagnetize the CRT
with degausser and verify that there is no occurrence of color
irregularity. (refer to Fig. 1-6)

Since the landing magnet is polarized,
check the screen’s improvement through
rotation, not only by position.
Fig 1-6
1-4. Beam Center Convergence Adjustment
Make adjustments on the convergence with 4-pole and 6-pole
magnets. Operate each magnet in relation to the electron beam
as shown in Figs. 1-7 and 1-8. When performing this
adjustment, verify whether there is distortion in the focus
adjustment. If necessary, carry out adjustments again.
In Fig. 1-7, two 4-pole magnets are stacked together so as to be of
the same polarity. Move the B and R beams to their respective
direction, by rotating the two 4-pole magnets together. By adjusting
the opening of the two magnets, it is possible to adjust the amount
of the beam’s movement.
Fig 1-8
In Fig. 1-8, the two 6-pole magnets are stacked together so as to be
of the same polarity. Move the B and R beams to their respective
direction, by rotating the two 6-pole magnets together. By adjusting
the opening of the two magnets, it is possible to adjust the amount
of the beam’s movement.
(1) Receive the dot pattern signal from the pattern generator.
(2) Pay attention to the center of the screen, and perform
adjustments with two 4-pole magnets so that the R beam and
B beam are perfectly aligned and become a magenta color.
(Refer to Fig. 1-2)
(3) In the same way, pay attention to the screen, and perform
adjustments with a 6-pole magnet so that the magenta beam
and G beam are aligned and become a white dot.
(Refer to Fig. 1-3)
(4) After adjustments are completed, secure all magnets with the
lock link. (Refer to Fig. 1-4)
1-5.The Surrounding Convergence Adjustment
Perform this adjustment after completion of adjustment 1-4.
(1) Shake the deflecting yoke up, down to the right and left, and
adjust any discrepancies in the screen’s surroundings.
(2) Insert wedges in three locations in the gap between the
deflecting yoke and the surface of the CRT funnel in order
to secure the deflecting yoke. (Refer to Fig. 1-9)
