SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
6. AVOID AN X-RAY
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
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
make sure not modify the circuit.
Repairing except indicates causes rising of high
voltage, and it emits an X-ray from the cathoderay tube.
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
serviced places serviced or not. Check the
insulation between the antenna terminal or
external metal and the AC cord plug blades.
And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these 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 TO DEAL WITH THE
CATHODE-RAY TUBE
1. Unplug the plug from the AC outlet.
2. Remove the antenna terminal on TV and turn
on the TV.
3. Insulation resistance between the cord plug
terminals and the eternal exposure metal
[Note 2] should be more than 1M ohm by
using the 500V insulation resistance meter
[Note 1].
4. If the insulation resistance is less than 1M
ohm, the inspection repair should be
required.
[Note 1]
In the condition that an explosion-proof cathoderay 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.
If you have not the 500V insulation
resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone jack

ADJUSTMENTS
NOTE
Adjust after performing adjustments in section 4-2.
NOTE
1. Receive the crosshatch pattern from the color bar
generator.
2. Combine red and blue of the 3 color crosshatch pattern
on the center of the screen by adjusting the pair of 4
pole magnets.
3. Combine red/blue (magenta) and green by adjusting the
pair of 6 pole magnets.
1. Turn the unit on and let it warm up for at least 30
minutes before performing the following adjustments.
2. Place the CRT surface facing east or west to reduce the
terrestrial magnetism.
3. Turn ON the unit and demagnetize with a Degauss Coil.
4-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)
1. Tighten the screw for the magnet. Refer to the adjusted
CRT for the position. (Refer to Fig. 4-1)
If the deflection yoke and magnet are in one body,
untighten the screw for the body.
2. Receive the green raster pattern from the color bar
generator.
3. Slide the deflection yoke until it touches the funnel side
of the CRT.
4. Adjust center of screen to green, with red and blue on
the sides, using the pair of purity magnets.
5. Switch the color bar generator from the green raster
pattern to the crosshatch pattern.
6. Combine red and blue of the 3 color crosshatch pattern
on the center of the screen by adjusting the pair of 4
pole magnets.
7. Combine red/blue (magenta) and green by adjusting the
pair of 6 pole magnets.
8. Adjust the crosshatch pattern to change to white by
repeating steps 6 and 7.
4-4: DYNAMIC CONVERGENCE
NOTE
Adjust after performing adjustments in section 4-3.
1. Adjust the differences around the screen by moving the
deflection yoke upward/downward and right/left.
(Refer to Fig. 4-2-a)
2. Insert three wedges between the deflection yoke and
CRT funnel to fix the deflection yoke.
(Refer to Fig. 4-2-b)
