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 re -
quest a repair of your TV. Do not attempt to repair the TV by yourself or remove the
rearcover 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 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 24 to
try to change the BLUE BACK function
setting to OFF.
• Are your SOUND SYSTEM settings for
the TV channels correct?
Forrow the description “SOUND SYSTEM
Button” on page 12 to try to solve the
trouble.
Poor picture
• If noise totally obscures the picture (sn-
ow), 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 dir-
ection?
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 compu-
ter, or a hair drier that can cause inter-
ference away from your TV, or try chan-
ging its location. If the aerial suffers int-
erference 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.
