SERVICING NOTICES ON CHECKING 1. 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 2]
External exposure metal: Antenna terminal Earphone jack

DISASSEMBLY INSTRUCTIONS 3. After one side is removed, pull in the opposite direction to remove the other.
3. REMOVAL OF ANODE CAP Read the following NOTED items before starting work.
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 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.
NOTE Confirm that there is no dirt, dust, etc. at the spot where the cap was located.

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.

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.)

PREVENTIVE CHECKS AND SERVICE INTERVALS CLEANING 2. TAPE RUNNING SYSTEM
NOTE
When cleaning the tape transport system, use the gauze moistened with isopropyl alcohol.
After cleaning the heads with isopropyl alcohol, do not run a tape until the heads dry completely. If the heads are not completely dry and alcohol gets on the tape, damage may occur.
3. CYLINDER Wrap a piece of chamois around your finger. Dip it in isopropyl alcohol. Hold it to the cylinder head softly. Turn the cylinder head counterclockwise to clean it (in the direction of the arrow). (Refer to the figure below.)
1. AUDIO CONTROL HEAD Clean the Audio Control Head with the cotton stick soaked by alcohol. Clean the full erase head in the same manner. (Refer to the figure below.)
NOTE Do not exert force against the cylinder head. Do not move the chamois upward or downward on the head. Use the chamois one by one.

PREPARATION FOR SERVICING How to use the Servicing Fixture 1. Unplug the connector CP353, then remove the TV/VCR Block from the set. Be sure to place the parts on a paper so that they have no short-circuit each other. 2. Unplug the connector CP810, CP820 and CP850, then remove the Main PWB from the VCR Block. 3. Connect as shown in the below figure using the Service Fixture. • Connect the Syscon PWB to the Main PWB with the cable JG162B and JG162G. • Connect the Syscon PWB to the CRT PWB with the cable JG162Y. 4. Short circuit between TP1001 and Ground with the cable JG154. (The BOT, EOT, and the Reel Sensor do not work and the deck can be operated without a cassette tape.) 5. In case of using a cassette tape, press the STOP/EJECT button to insert or eject a cassette tape. Turn on the power and re-check the cable before checking the trouble points.
