SERVICING NOTICES ON CHECKING

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 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

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.

6. AVOID AN X-RAY1. KEEP THE NOTICES

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.

PERFORM A SAFETY CHECK AFTER

7. 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.

ATTACHMENTS

Do not use attachments not recommended by the unit’s manufacturer as they may cause hazards.

WATER AND MOISTURE

Do not use this unit near water. For example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool.

ACCESSORIES

Do not place this unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall, causing serious injury, and serious damage to the unit. Use only with a cart, stand, tripod, bracket, or table recommended by the manufacturer.

8A.

An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn.

VENTILATION

Slots and openings in the cabinet and in the back or bottom are provided for ventilation, to ensure reliable operation of the unit, and to protect it from overheating. These openings must not be blocked or covered. The openings should never be blocked by placing the unit on a bed, sofa, rug, or other similar surface. This unit should never be placed near or over a radiator or heat source. This unit should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions have been adhered to.

10.

POWER SOURCES

This unit should be operated only from the type of power source indicated on the rating plate. If you are not sure of the type of power supply to your home, consult your appliance dealer or local power company . For units intended to operate from battery power, or other sources, refer to the operating instructions.

11.

GROUNDING OR POLARIZATION

This unit is equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way . This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. If your unit is equipped with a 3-wire grounding-type plug, a plug having a third (grounding) pin, this plug will only fit into a grounding-type power outlet. This too, is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.

12.

POWER-CORD PROTECTION

3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)

Tighten the screw for the magnet. Refer to the adjusted

1. CRT for the position. (Refer to Fig. 3-1) If the deflection yoke and magnet are in one body, untighten the screw for the body. Receive the green raster pattern from the color bar

2. generator. Slide the deflection yoke until it touches the funnel

3. side of the CRT. Adjust center of screen to green, with red and blue on the

4. sides, using the pair of purity magnets. Switch the color bar generator from the green raster

5. pattern to the crosshatch pattern. Combine red and blue of the 3 color crosshatch pattern

6. on the center of the screen by adjusting the pair of 4 pole magnets. Combine red/blue (magenta) and green by adjusting the

7. pair of 6 pole magnets. Adjust the crosshatch pattern to change to white

8. by repeating steps 6 and 7.

3-2: PURITY NOTE

Adjust after performing adjustments in section 3-1.

3-3: STATIC CONVERGENCE

NOTE

Adjust after performing adjustments in section 3-2.

Receive the crosshatch pattern from the color bar generator.

Combine red and blue of the 3 color crosshatch pattern on the center of the screen by adjusting the pair of 4 pole magnets.

Combine red/blue (magenta) and green by adjusting the pair of 6 pole magnets.

3-4: DYNAMIC CONVERGENCE

NOTE

Adjust after performing adjustments in section 3-3.

1.2.Adjust the differences around the screen by moving the deflection yoke upward/downward and right/left.

(Refer to Fig. 3-2-a)

Insert three wedges between the deflection yoke and CRT funnel to fix the deflection yoke.

Receive the green raster pattern from color bar generator.

Adjust the pair of purity magnets to center the color on the screen. Adjust the pair of purity magnets so the color at the ends are equally wide.

Move the deflection yoke backward (to neck side) slowly, and stop it at the position when the whole screen is green.

Confirm red and blue colors.

Adjust the slant of the deflection yoke while watching the screen, then tighten the fixing screw.
