SERVICING NOTICES ON CHECKING
6. AVOID AN X-RAY1. KEEP THE NOTICES
As for the places which need special attentions,they are indicated with the labels or seals on thecabinet, chassis and parts. Make sure to keep theindications and notices in the operation manual.
3. USE THE DESIGNATED PARTS
5. TAKE CARE TO DEAL WITH THECATHODE-RAY TUBE
In the condition that an explosion-proof cathode-ray tube is set in this equipment, safety issecured against implosion. However, whenremoving it or serving from backward, it isdangerous to give a shock. Take enough care todeal with it.
Safety is secured against an X-ray by consider-ing about the cathode-ray tube and the highvoltage peripheral circuit, etc.Therefore, when repairing the high voltage pe-ripheral circuit, use the designated parts andmake sure not modify the circuit.Repairing except indicates causes rising of highvoltage, and it emits an X-ray from the cathode-ray tube.
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be found at the end of the SERIAL NUMBER.2. PART NO. and DESCRIPTION
You can find it in your SERVICE MANUAL.
HOW TO ORDER PARTS
PERFORM A SAFETY CHECK AFTERSERVICING
7.
Confirm that the screws, parts and wiring whichwere removed in order to service are put in theoriginal positions, or whether there are theportions which are deteriorated around theserviced places serviced or not. Check theinsulation between the antenna terminal orexternal metal and the AC cord plug blades.And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
1.2.
3.
4.
Unplug the plug from the AC outlet.Remove the antenna terminal on TV and turnon the TV.Insulation resistance between the cord plugterminals and the eternal exposure metal[Note 2] should be more than 1M ohm byusing the 500V insulation resistance meter[Note 1].If the insulation resistance is less than 1Mohm, the inspection repair should berequired.
[Note 1]
If you have not the 500V insulationresistance meter, use a Tester.
[Note 2]External exposure metal: Antenna terminal
Earphone jack
2. AVOID AN ELECTRIC SHOCKThere is a high voltage part inside. Avoid anelectric shock while the electric current isflowing.
The parts in this equipment have the specificcharacters of incombustibility and withstandvoltage for safety. Therefore, the part which isreplaced should be used the part which hasthe same character.Especially as to the important parts for safetywhich is indicated in the circuit diagram or thetable of parts as a mark, the designatedparts must be used.
4. PUT PARTS AND WIRES IN THEORIGINAL POSITION AFTERASSEMBLING OR WIRINGThere are parts which use the insulationmaterial such as a tube or tape for safety, orwhich are assembled in the condition thatthese do not contact with the printed board.The inside wiring is designed not to get closerto the pyrogenic parts and high voltage parts.Therefore, put these parts in the originalpositions.

3. REMOVAL OF ANODE CAPRead the following NOTED items before starting work.
After turning the power off there might still be a potentialvoltage that is very dangerous. When removing theAnode Cap, make sure to discharge the Anode Cap'spotential voltage.Do not use pliers to loosen or tighten the Anode Capterminal, this may cause the spring to be damaged.
*
*
REMOVAL
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 aflat-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 theScrewdriver.A cracking noise will be heard as the voltage is discharged.

CLEANINGNOTE
After cleaning the heads with isopropyl alcohol, do notrun a tape until the heads dry completely. If the headsare not completely dry and alcohol gets on the tape,damage may occur.
1. AUDIO CONTROL HEAD
Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol and clean the audio control head bywiping it horizontally. Clean the full erase head in thesame manner. (Refer to the figure below.)

Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol. Hold it to the cylinder head softly.Turn the cylinder head counterclockwise to clean it (inthe direction of the arrow). (Refer to the figure below.)
NOTE
Do not exert force against the cylinder head. Do not movethe chamois upward or downward on the head.Use the chamois one by one.

NOTE FOR THE REPLACING OF MEMORY IC
If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken toensure correct data settings while making reference to TABLE 1.
NOTE:

Place an object which weighs between 450g~500g onthe Cassette Tape to keep it steady when you want tomake the tape run without the Cassette Holder. (Do notplace an object which weighs over 500g.)When you activate the deck without the CassetteHolder, short circuit between TP1001 and GND. (Referto ELECTRICAL ADJUSTMENT PARTS LOCATIONGUIDE) In this condition the BOT/EOT/Reel Sensor willnot function.
