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. 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 cathode-ray tube. 2. AVOID AN ELECTRIC SHOCK There is a high voltage part inside. Avoid an electric shock while the electric current is flowing. 7. PERFORM A SAFETY CHECK AFTER SERVICING 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. 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. 4. PUT PARTS AND WIRES IN THE ORIGINAL POSITION AFTER ASSEMBLING OR WIRING (INSULATION CHECK PROCEDURE) 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. 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 [Note 1] In the condition that 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 enough care to deal with it. If you have not the 500V insulation resistance meter, use a Tester.

NOTE * 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. 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. 3-3.) REMOVAL Location of Anode Cap 1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. 3-1.) 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. Fig. 3-3 GND on the CRT 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. 3-4.) CRT Screwdriver Support Alligator Clip GND on the CRT Fig. 3-4 Fig. 3-1 4. Insert one end of the Anode Support into the anode button, then the other as shown in Fig. 3-5. 2. Flip up the sides of the Rubber Cap in the direction of the arrow and remove one side of the support. (Refer to Fig. 3-2.) Rubber Cap CRT CRT Support Support Fig. 3-5 Fig. 3-2 5. Confirm that the Support is securely connected. 6. Put on the Rubber Cap without moving any parts. B3-1 DISASSEMBLY INSTRUCTIONS 3. When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using a tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 4-3.) 4. REMOVAL AND INSTALLATION OF FLAT PACKAGE IC REMOVAL NOTE 1. Put the Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 4-1.) Some ICs on the PWB are affixed with glue, so be careful not to break or damage the foil of each IC leads or solder lands under the IC when removing it. NOTE Masking is carried out on all the parts located within 10 mm distance from IC leads. Masking Tape (Cotton Tape) Blower type IC desoldering machine IC Tweezers Fig. 4-1 IC Fig. 4-3 2. Heat the IC leads using a blower type IC desoldering machine. (Refer to Fig. 4-2.) 4. Peel off the Masking Tape. NOTE 5. Absorb the solder left on the pattern using the Braided Shield Wire. (Refer to Fig. 4-4.) Do not add the rotating and the back and forth directions force on the IC, until IC can move back and forth easily after desoldering the IC leads completely. NOTE Do not move the Braided Shield Wire in the vertical direction towards the IC pattern. Blower type IC desoldering machine Braided Shield Wire Soldering Iron IC IC pattern Fig. 4-2 B4-1 Fig. 4-4 DISASSEMBLY INSTRUCTIONS INSTALLATION 4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 4-8.) 1. Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily. (Refer to Fig. 4-5.) Thin-tip Soldering Iron IC Soldering Iron Fig. 4-8 5. Finally, confirm the soldering status on four sides of the IC using a magnifying glass. 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. Solder temporarily Solder temporarily Fig. 4-5 2. Supply the solder from the upper position of IC leads sliding to the lower position of the IC leads. (Refer to Fig. 4-6.) Solder IC 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. Soldering Iron Supply soldering from upper position to lower position Fig. 4-6 3. Absorb the solder left on the lead using the Braided Shield Wire. (Refer to Fig. 4-7.) NOTE Do not absorb the solder to excess.
