Troubleshooting
Additional Information
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 high
directional antenna may improve the picture.

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. SOUND MODE and
L
.
Notes
• When you turn on the TV, you may hear the “boom” 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
U
on the TV
to turn off the TV for five minutes and then turn it on again.
• The TV illustration of KV-J14 models have been used for
illustration purpose in this manual.
• Design and specifications are subject to change without notice.
• All contents in the instruction manual are subject to change
without notice.

2 Using a thumb press down, then pull up the rubber cap firmly in the direction
indicated by the arrow b.
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.
• HOW TO HANDLE AN ANODE-CAP
1 Do not damage the surface of anode-cap with sharp shaped objects.
2 Do not press the rubber too hard so as not to damage the inside of anode-cap.
A metal fitting called the shatter-hook terminal is built into the rubber.
3 Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage the rubber.
•REMOVAL OF ANODE-CAP
NOTE : After removing the anode, short circuit the anode of the picture tube and the anode
cap to the metal chassis, CRT shield or carbon paint on the CRT.
•REMOVING PROCEDURES
1 Turn up one side of the rubber cap in the direction indicated by the arrow a.

• 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
Perform the adjustments in the following order:
1. Beam Landing
2. Convergence
3. Focus
4. White Balance

SET-UP ADJUSTMENTS
................................................................................................................................................................................................................................
Preparation :
• In order to reduce the influence of geomagnetism on the set's
picture tube, face it east or west.
• Switch on the power and degauss with the degausser.
3-1. BEAM LANDING
1. Input a white 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 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.)

3-2. CONVERGENCE
Preparation :
• Before starting this adjustment, adjust the focus, horizontal size,
and vertical size.
• Minimize the brightness setting.
• Provide dot pattern.
(1) Horizontal and Vertical Static Convergence
1. (Moving vertically), adjust the V.STAT magnet so that the red,
green and blue dots are on top of each other at the center of the
screen.
2. (Moving horizontally), adjust the H.STAT VR so that the red,
green and blue dots are on top of each other at the center of the
screen.
• Operation of V.STAT magnet.
If the V.STAT magnet is moved in the direction of the a and
b arrows, the red, green and blue dots move as shown below.
• Operation of BMC (Hexapole) magnet.
If the blue or red dot does not converge with the other tw o dots,
perform following steps.
Move BMC magnet (a) to correct insufficient H.static
convergence.
Rotate BMC magnet (b) to correct insufficient V.static
convergence.
In either case, repeat Beam Landing Adjustment.
