If a problem arises while you are using the TV, please read this “Troubleshooting” well before you request having the TV repaired.
You may be able to fix it easily by yourself. For example, if the AC plug is disconnected from the AC outlet, or the TV aerial has
problems, you may think there is a problem with the TV itself.
Important:
•
This Troubleshooting guide only covers problems whose cause are not easy to determine. If a question arise when you are
operating a function, read the page(s) corresponding to the operation of the function well, not this Troubleshooting guide.
•
After you have followed the Troubleshooting description or the operating description of the functions concerned without any suc-
cess, remove the AC plug from the AC outlet and request a repair of your TV. Do not attempt to repair the TV by yourself or
remove the rear cover of the TV.

Have you chosen a TV channel whose reception is extreme-
ly bad? In this case, the BLUE BACK function will be activat-
ed, the entire screen becomes blue, and the sound is muted.
In spite of this, if you want to view the TV channel, follow the
description “BLUE BACK” on page 21 to try to change the
BLUE BACK function setting to OFF.
•
Have you connected the headphones to the TV? Connect-
ing the headphones to the TV causes sounds not to be is-
sued from the TV speakers.
•
Have you set the SPEAKER function to OFF? Follow the de-
scription “SPEAKER” on page 18 to confirm the SPEAKER
function setting to try to solve the problem.
•
If the SYSTEM setting for a TV channel is incorrect, it may
prevent the sound from being issued. Follow the description

•
If noise totally obscures the picture (snow), the aerial or aer-
ial cable may have trouble. Check the following to try to
solve the trouble:
Has the TV and aerial been connected properly?
Has the aerial cable been damaged?
Is the aerial pointed to the right direction?
Is the aerial itself faulty?
•
If the TV or aerial receives interference from the other devic-
es, stripes or noise may appear in the picture. Move such
devices as an amplifier, personal computer, or a hair drier
that can cause interference away from your TV, or try
changing its location. If the aerial suffers interference from a
radio tower or high-voltage wire, please contact your local
dealer.
•
If the TV receives interference from signal reflecting from
mountains or building, double-pictures (ghosting) will occur.
Try to change the aerial’s direction or replace the antenna
with the one with better directionality.
•
Are your COLOUR SYSTEM settings for the TV channels
correct? Follow the description “COLOUR SYSTEM” on
page 17 to try to solve the trouble.
•
Has COLOUR or BRIGHT been controlled properly? Follow
the description “Picture Adjustment” on page 15 to try to ad-
just them properly.
•
Videotaping teletext is not recommended because it may
not record correctly.
•
When a white and bright still image (such as a white dress)
is displayed on the screen, the white part may look as if it
were coloured. It is a phenomenon unavoidable due to the
nature of the picture tube itself, and not due to a TV failure.
When the picture disappears from the screen, the unnatural
colours will also disappear.
•
When viewing images from commercially available video
software products, or videos from videotapes which have
been recorded improperly, the top of the image may be dis-
torted. This is due to the condition of the video signal, and
not because of malfunction.

ed? Follow the description “Putting Batteries into the Re-
mote Control” on page 2 and replace them with new
batteries to try to solve the problem.
•
Have you attempted to use the remote control at the sides
or rear of the TV or at a location more than seven meters
apart from the TV location? Operate the remote control in
the front of your TV or a location less than seven meters
from your TV to try to solve the problem.
•
When you are viewing a teletext programme, you cannot op-
erate the menus. Press the
b
button to return the teletext
programme to the ordinary TV programme to try operating
the menus.
•
If the TV operation becomes disabled suddenly, press the
Main power button on the TV and turn off the main power.
Try to press the Main power button again to turn on the main
power. If the TV returns to a normal state, it is not a failure.
