Troubleshooting
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 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 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 27 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.
„ Poor picture
• 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 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 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 directionality.
• Are your COLOUR SYSTEM settings
for the TV channels correct? Follow
the description “COLOUR SYSTEM
button” on page 11 to try to solve the
trouble.
• Has COLOUR or BRIGHT been
controlled properly? Follow the
description “Adjusting the picture” on
page 20 to try to adjust them properly.
• Videotaping teletext is not
recommended because it may not
record correctly.
