6. AVOID AN X-RAY1. KEEP THE NOTICES

5. TAKE CARE TO DEAL WITH THE

CATHODE-RAY TUBE

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.

Safety is secured against an X-ray by consider-

ing about the cathode-ray tube and the high

voltage peripheral circuit, etc.

Therefore, when repairing the high voltage pe-

ripheral 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.

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.

IMPORTANT

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 the

cabinet, chassis and parts. Make sure to keep the

indications and notices in the operation manual.

2. AVOID AN ELECTRIC SHOCK

There is a high voltage part inside. Avoid an

electric shock while the electric current is

flowing.

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.

PUT PARTS AND WIRES IN THE

ORIGINAL POSITION AFTER

ASSEMBLING OR WIRING

4.

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.

7. PERFORM A SAFETY CHECK AFTER

SERVICING

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.

(INSULATION CHECK PROCEDURE)

1.

2.

3.

4.

Unplug the plug from the AC outlet.

Remove the antenna terminal on TV and turn

on the TV.

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].

If the insulation resistance is less than 1M

ohm, the inspection repair should be

required.

[Note 1]

If you have not the 500V insulation

resistance meter, use a Tester.

[Note 2]

1. REMOVAL OF ANODE CAP

Read the following NOTED items before starting work.

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.

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 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.

Flip up the sides of the Rubber Cap in the direction of the

arrow and remove one side of the support.

(Refer to Fig. 1-2.)

NOTE

REMOVAL AND INSTALLATION OF

FLAT PACKAGE IC

Some ICs on the PCB are affixed with glue, so be

careful not to break or damage the foil of each IC

NOTE

Masking is carried out on all the parts located within

10 mm distance from IC leads.

NOTE

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.

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. 2-3.)

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.

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.

INSTALLATION

Take care of the polarity of new IC and then install the

ELECTRICAL ADJUSTMENTS

1.BEFORE MAKING ELECTRICAL

ADJUSTMENTS

Read and perform these adjustments when repairing the

circuits or replacing electrical parts or PCB assemblies.

CAUTION

•

Use an isolation transformer when performing any

service on this chassis.

Before removing the anode cap, discharge electricity

because it contains high voltage.

When removing a PCB or related component, after

unfastening or changing a wire, be sure to put the wire

back in its original position.

Inferior silicon grease can damage IC's and transistors.

When replacing IC's and transistors, use only specified

silicon grease (YG6260M).

Remove all old silicon before applying new silicon.

Receive the green raster pattern from color bar

generator.

Adjust the pair of purity magnets to center the

color on the screen.

Adjust the pair of purity magnets so the color at the

ends are equally wide.

Move the deflection yoke backward (to neck side)

slowly, and stop it at the position when the whole

screen is green.

Confirm red and blue colors.

Adjust the slant of the deflection yoke while watching the

screen, then tighten the fixing screw.

ADJUSTMENTS

NOTE

3-1: STATIC CONVERGENCE (ROUGH ADJUSTMENT)

Tighten the screw for the magnet. Refer to the adjusted

CRT 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 bar

generator.

Slide the deflection yoke until it touches the funnel

side of the CRT.

Adjust center of screen to green, with red and blue on the

sides, using the pair of purity magnets.

Switch the color bar generator from the green raster

pattern to the crosshatch pattern.

Combine red and blue of the 3 color crosshatch pattern

on the center of the screen by adjusting the pair of

4 pole magnets.

Combine red/blue (magenta) and green by adjusting the

pair of 6 pole magnets.

Adjust the crosshatch pattern to change to white

by repeating steps 6 and 7.

Turn the unit on and let it warm up for at least 30

minutes before performing the following adjustments.

Place the CRT surface facing east or west to reduce the

terrestrial magnetism.

Turn ON the unit and demagnetize with a Degauss Coil.

Adjust after performing adjustments in section 3-2.

Adjust the differences around the screen by moving

the deflection yoke upward/downward and right/left.

(Refer to Fig. 3-2-a)

Insert three wedges between the deflection yoke and

CRT funnel to fix the deflection yoke.
