Troubleshooting

If you have any problems, read this manual again and check the countermeasure for each of the symptoms listed below. If the problem persists after trying the methods below, contact your nearest authorized service center or dealer.

Snowy picture Noisy sound

/Check the antenna. /Check the antenna connection on the TV

and on the wall.

Dotted lines or stripes

/This may be caused by local interference

(e.g. cars, neon signs and hair dryers). Adjust the antenna for minimum interference.

Double images or “ghosts”

/This may be caused by reflections from

nearby mountains or buildings. A highly directional antenna may improve the picture.

Additional Information

No picture No sound

/Press

or u.

/Check the antenna connection. /Check the VCR connections. /Check the power cord connection. /Check the standby mode.

Good picture No sound

/Press

No color

/Adjust the COLOR level in the on-screen

display.

/Check the COLOR SYSTEM setting.

TV cabinet creaks

/Even if the picture or the sound is normal,

changes in the room temperature sometimes make the TV cabinet expand or contract, making a noise. This does not indicate a malfunction.

Note on the remote commander

• The supplied remote commander is used on several models of

the TV. If you do not find instructions for some controls that are on the remote commander, that means your TV does not employ the features of those controls, e.g.

and SOUND

MODE.

Notes

• When you turn on the TV, you may hear the “boon” sound

that is caused by the demagnetization of the TV. This does not indicate a malfunction.

• The picture color may become abnormal if you change the

direction of your TV. To obtain the normal picture color, press

on the TV to turn off the TV for five minutes and then turn

it on again.

• Design and specifications are subject to change without notice.

• All contents in the instruction manual are subject to change

without notice.

CRT, after removing the anode.

•REMOVING PROCEDURES

1 Turn up one side of the rubber cap in

the direction indicated by the arrow a.

• HOW TO HANDLE AN ANODE-CAP

1 Don’t hurt the surface of anode-caps with

sharp shaped objects!

2 Don’t press the rubber too hard so as not to

damage the inside of anode-caps! A material fitting called the shatter-hook terminal is built into the rubber.

3 Don’t turn the foot of rubber over too hard!

The shatter-hook terminal will stick out or damage the rubber.

2 Using a thumb, pull up the rubber

cap firmly in the direction indicated by the arrow b.

Anode button

3 When one side of the rubber cap is

separated from the anode button, the anode-cap can be removed by turning up the rubber cap and pulling it up in the direction of the arrow c.

Disk magnets or rotatable disk magnets correct these areas (a-d).

SET-UP ADJUSTMENTS

• The following adjustments should be made when a complete

realignment is required or a new picture tube is installed.

• These adjustments should be performed with rated power

supply voltage unless otherwise noted.

Controls and switch should be set as follows unless otherwise noted:

PICTURE control........................................................... normal

BRIGHTNESS control................................................... normal

.................................................................................................................................................................................................................................

Preparations :

• In order to reduce the influence of geomagnetism on the set's

picture tube, face it east or west.

• Switch on the set's power and degauss with the degausser.

3-1. BEAM LANDING

1. Input the white raster signal with the pattern generator. Contrast Brightness

2. Set the pattern generator raster signal to green.

3. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.)

4. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.)

5. Switch the raster signal to blue, then to red and verify the condition.

6. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws.

7. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)
