6. AVOID AN X-RAY1. KEEP THE NOTICES
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.
Inferior silicon grease can damage IC's and transistors.When replacing an IC's or transistors, use only specified silicon grease (YG6260M).Remove all old silicon before applying new silicon.

HOW TO ORDER PARTS
SERVICING NOTICES ON CHECKING
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.
2. AVOID AN ELECTRIC SHOCKThere is a high voltage part inside. Avoid anelectric shock while the electric current isflowing.
3. USE THE DESIGNATED PARTSThe 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.
PUT PARTS AND WIRES IN THEORIGINAL POSITION AFTERASSEMBLING OR WIRING
4.
There 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.
7. PERFORM A SAFETY CHECK AFTERSERVICING
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.

1. 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
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 ofa 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 thescrewdriver.A cracking noise will be heard as the voltage is discharged.
Flip up the sides of the Rubber Cap in the direction of thearrow and remove one side of the support.(Refer to Fig. 1-2.)

NOTE
REMOVAL AND INSTALLATION OFFLAT PACKAGE IC
Some ICs on the PCB are affixed with glue, so becareful not to break or damage the foil of each ICleads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within10 mm distance from IC leads.

ELECTRICAL ADJUSTMENTS
1.
Read and perform these adjustments when repairing thecircuits or replacing electrical parts or PCB assemblies.
CAUTION
•
•
•
•
Use an isolation transformer when performing any service onthis chassis.Before removing the anode cap, discharge electricity becauseit contains high voltage.When removing a PCB or related component, afterunfastening or changing a wire, be sure to put the wire backin its original position.Inferior silicon grease can damage IC's and transistors. WhenWhen you exchange IC and Transistor for a heat sink,apply the silicon grease (YG6260M) on the contractsection of the heat sink, Before applying new silicongrease, remove all the old silicon grease. (Old greasemay cause damages to the IC and Transistor.)
