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 7.3 M to 10.1 M when applying
2) In the voltage withstand test, apply 3.0 kV for 1 minute and check that the GO lamp lights.

* 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 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 so that these parts 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 of the cathode-ray tube. By setting an explosion-proof cathode-ray 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
6. Avoid an X-ray. Safety is secured against an X-ray by considering
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 the portions which are deteriorated around the places serviced.

DISASSEMBLY INSTRUCTIONS
1. REAR CABINET REMOVAL
(1) Remove eight screws 1, then remove the rear cabinet in
the direction of the arrow. (See Figure1-1)
2. HIGH-VOLTAGE CAP (ANODE CAP) REMOVAL
Front cabinet
Rear cabinet
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.

Discharge the anode voltage. (See Figure 2-1)
(1) Connect a flat-bladed screwdriver to the CRT GND via
an alligator clip.
(2) Use a tester to check the end of the screwdriver and ground
of the TV for continuity.
(3) Touch the hook with the end of the screwdriver.
Caution : Be careful not to damage the anode cap.
(4) Turn over the anode cap.

(6) Turn over the anode cap on the side where the hook was
released and pull out the cap in the direction opposite to that on which the cap was pushed. (See Figure 2-4)
Caution : Do not pull out the anode cap straight up.
: Do not pull the cap forcibly. After removing
the cap, check that the hook is not deformed.
3. ANODE CAP REINSTALLTION
Observe the cautions carefully so that no accident occurs due to a defect in installing the anode cap and so it does not come off.

3-1. Caution before Reinstalling
Never turn the anode cap after installing it
Never re-use the hook when it has been deformed
(1) If the anode cap is turned after it is installed, it may come
off. Therefore, arrange the high-voltage cable before attaching the anode cap. (See Figure 3-1)
(2) If you have attached the anode cap before arranging the
high-voltage cable, arrange the cable carefully so the cap does not turn.
3-2. Anode cap reinstallation
(1) Use a clean cloth moistened slightly with alcohol to clean
the installation section. (See Figure 3-2) Caution : Check that the installation section is free from
dust, foreign matter, etc.
(2) Coat the anode cap installation circumference with an
appropriate amount of the specified silicone grease (KS­650N). Caution : Be careful that silicone grease does not enter
the anode button.

(3) Eliminate twisting, etc. of the high-voltage cable and
arrange it so that no twisting occurs. (See Figure 3-3) Caution : If the cable is not arranged correctly, the anode
cap could turn and cause an installation defect.
(4) Turn over the rubber cap symmetrically on the left and
right. (See Figure 3-4) Caution : Take great care not to damage the anode cap.
