SERVICING NOTICES ON CHECKING
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.
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.
[Note 2]
External exposure metal: Antenna terminal Earphone jack
HOW TO ORDER PARTS
Please include the following informations when you order parts. (Particularly the VERSION LETTER.) 1.

DISASSEMBLY INSTRUCTIONS
1. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work. * After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage. * Do not use pliers to loosen or tighten the Anode Cap terminal, this may cause the spring to be damaged. REMOVAL 1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. 1-1.) Connect one end of an Alligator Clip to the metal part of a flat-blade screwdriver and the other end to ground. While holding the plastic part of the insulated Screwdriver, touch the support of the Anode with the tip of the Screwdriver. A cracking noise will be heard as the voltage is discharged. Location of Anode Cap 3. After one side is removed, pull in the opposite direction to remove the other. NOTE Take care not to damage the Rubber Cap. INSTALLATION 1. Clean the spot where the cap was located with a small amount of alcohol. (Refer to Fig. 1-3.)
GND on the CRT Fig. 1-3 NOTE Confirm that there is no dirt, dust, etc. at the spot where the cap was located. 2. Arrange the wire of the Anode Cap and make sure the wire is not twisted. 3. Turn over the Rubber Cap. (Refer to Fig. 1-4.)

Confirm that no abnormality is found on the soldering position and installation position of the parts around the IC. If some abnormality is found, correct by resoldering. NOTE When the IC leads are bent during soldering and/or repairing, do not repair the bending of leads. If the bending of leads are repaired, the pattern may be damaged. So, be always sure to replace the IC in this case.

ELECTRICAL ADJUSTMENTS
2-13: COLOR CENT 1. Receive the PAL color bar pattern. (RF Input) 2. Using the remote control, set the brightness, contrast and color to normal position. 3. Connect the oscilloscope to TP801. 4. Activate the adjustment mode display of Fig. 1-1 and press the channel button (25) on the remote control to select "COLOR CENT". 5. Adjust the VOLTS RANGE VARIABLE knob of the oscilloscope until the range between white 100% and 0% is set to 4 scales on the screen of the oscilloscope. 6. Press the VOL. +/- button on the remote control until the red color level is adjusted to 90 ± 10% of the white level. (Refer to Fig. 2-1) 7. Receive the PAL color bar pattern. (Audio Video Input) 8.

ELECTRICAL ADJUSTMENTS
3. PURITY AND CONVERGENCE ADJUSTMENTS
NOTE 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. 3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT) 1. Tighten the screw for the magnet. Refer to the adjusted 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. 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. 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. DEFLECTION YOKE DEFLECTION YOKE SCREW MAGNET SCREW 3-3: STATIC CONVERGENCE NOTE Adjust after performing adjustments in section 3-2. 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. 3-4: DYNAMIC CONVERGENCE NOTE Adjust after performing adjustments in section 3-3. 1. Adjust the differences around the screen by moving the deflection yoke upward/downward and right/left. (Refer to Fig. 3-2-a) 2. Insert three wedges between the deflection yoke and CRT funnel to fix the deflection yoke. (Refer to Fig. 3-2-b) RGB RGB
