Troubleshooting
Important:
• This Troubleshooting guide only covers problems whose causes 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 success, 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.
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.
IF YOU CANNOT TURN ON THE TV
• Is the AC plug connected to the AC outlet?
• Is the POWER lamp lit? If not, press the Main
power button.
NO PICTURE/NO SOUND
• Have you chosen a TV channel whose
reception is extremely bad? In this case, the
BLUE BACK function will be activated, 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 9 to try to change the
BLUE BACK function setting to OFF.
• Are your SOUND SYSTEM settings for the
TV channels correct? Follow the description
“SOUND SYSTEM button” on page 11 to try
to solve the trouble.
IF YOU CANNOT TURN ON THE TV
• If noise totally obscures the picture (snow),
the aerial or aerial cable may have trouble.
Check the following to try to solve the
trouble: Has the TV and aerial been con-
nected 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 devices, stripes or noise may
appear in the picture. Move such device 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 interferences 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 directional-
ity.
• Are your COLOUR SYSTEM settings for the
TV channels correct? Follow the description
“COLOUR SYSTEM button” on page 8 to try
to solve the trouble.
• Has COLOUR or BRIGHT been controlled
properly? Follow the description “PICTURE
SETTING” on page 8 to try to adjust 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
distorted. This is due to the condition of the
video signal, and not because of malfunction.
