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 make sure not modify the circuit. Repairing except indicates causes rising of high voltage, and it emits an X-ray from the cathoderay tube.
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.
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)
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.
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]
If you have not the 500V insulation resistance meter, use a Tester.

For example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool. PORTABLE CART WARNING (symbol provided by RETAC) 8. 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. S3126A 9. 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 Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance. 13.

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. 3-2: PURITY NOTE Adjust after performing adjustments in section 3-1. 1. Receive the green raster pattern from color bar generator. 2. 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. 3. Move the deflection yoke backward (to neck side) slowly, and stop it at the position when the whole screen is green. 4. Confirm red and blue colors. 5. Adjust the slant of the deflection yoke while watching the screen, then tighten the fixing screw.
