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 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 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 26 to try to change the BLUE BACK
function setting to OFF.
• Have you connected the headphones to
the TV? Connecting the headphones to
the TV causes sounds not to be issued
from the TV speakers.
• If the SYSTEM setting for a TV channel
is incorrect, it may prevent the sound
from being issued. Follow the description
“EDIT/MANUAL” on page 27 to use the
MANUAL function to try to change the
SYSTEM setting.
„ 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
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 21 to try to solve the trouble.
