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.

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.

[Note 2]External exposure metal: Antenna terminal

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

Take care not to damage the Rubber Cap.

INSTALLATION

1. Clean the spot where the cap was located with a smallamount of alcohol. (Refer to Fig. 1-3.)

Location of Anode Cap

NOTE

Confirm that there is no dirt, dust, etc. at the spot wherethe cap was located.

2.

3.

Arrange the wire of the Anode Cap and make sure thewire is not twisted.Turn over the Rubber Cap. (Refer to Fig. 1-4.)

4. Insert one end of the Anode Support into the anode button,then the other as shown in Fig. 1-5.

5.6.

Confirm that the Support is securely connected.Put on the Rubber Cap without moving any parts.

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.

Blower type ICdesoldering machine

IC

Heat the IC leads using a blower type IC desolderingmachine. (Refer to Fig. 2-2.)

2.

Fig. 2-2

NOTE

Do not add the rotating and the back and forthdirections force on the IC, until IC can move back andforth easily after desoldering the IC leads completely.

When IC starts moving back and forth easily afterdesoldering completely, pickup the corner of the IC usinga tweezers and remove the IC by moving with the ICdesoldering machine. (Refer to Fig. 2-3.)

NOTE

When the IC leads are bent during soldering and/orrepairing, do not repair the bending of leads. If thebending of leads are repaired, the pattern may bedamaged. So, be always sure to replace the IC in thiscase.

Finally, confirm the soldering status on four sides of theIC using a magnifying glass.Confirm that no abnormality is found on the solderingposition and installation position of the parts around theIC. If some abnormality is found, correct by resoldering.

Read and perform these adjustments when repairing thecircuits or replacing electrical parts or PCB assemblies.

CAUTION

•

•

•

•

Use an isolation transformer when performing any serviceon this chassis.Before removing the anode cap, discharge electricitybecause it contains high voltage.When removing a PCB or related component, afterunfastening or changing a wire, be sure to put the wireback in its original position.When 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.)

Receive the green raster pattern from color bargenerator.Adjust the pair of purity magnets to center thecolor on the screen.Adjust the pair of purity magnets so the color at theends are equally wide.Move the deflection yoke backward (to neck side)slowly, and stop it at the position when the wholescreen is green.Confirm red and blue colors.Adjust the slant of the deflection yoke while watchingthe screen, then tighten the fixing screw.

NOTE

3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)

Tighten the screw for the magnet. Refer to the adjustedCRT for the position. (Refer to Fig. 3-1)If the deflection yoke and magnet are in one body,untighten the screw for the body.Receive the green raster pattern from the color bargenerator.Slide the deflection yoke until it touches the funnelside of the CRT.Adjust center of screen to green, with red and blue onthe sides, using the pair of purity magnets.Switch the color bar generator from the green rasterpattern to the crosshatch pattern.Combine red and blue of the 3 color crosshatch patternon the center of the screen by adjusting the pair of4 pole magnets.Combine red/blue (magenta) and green by adjustingthe pair of 6 pole magnets.Adjust the crosshatch pattern to change to whiteby repeating steps 6 and 7.

Turn the unit on and let it warm up for at least 30minutes before performing the following adjustments.Place the CRT surface facing east or west to reduce theterrestrial magnetism.Turn ON the unit and demagnetize with a Degauss Coil.
