Troubleshooting
If a problem arises while you are using the TV, please read this troubleshooting guide carefully
before you ask to have the TV repaired. You may be able to fix it easily by yourself. For example,
if the mains plug is disconnected from the mains 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 decide. If you
have a question when you are operating a function, read the page(s) for that function carefully,
not this troubleshooting guide.
• If you follow the advice in this troubleshooting guide without any success, unplug the mains
plug and ask for your TV to be repaired. Do not attempt to repair the TV by yourself or to
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.
• Make sure you set the VCR/TV/DVD
switch to the TV position. You cannot
turn the TV on when the VCR/TV/DVD
switch is set to the VCR or DVD position.

If you cannot turn off the TV

• Make sure you set the VCR/TV/DVD
switch to the TV position. You cannot
turn the TV off when the VCR/TV/DVD
switch is set to the VCR or DVD position.

No picture or no sound

• Have you chosen a TV channel with very
poor reception? If so, the BLUE BACK
function will be activated: the entire
screen becomes blue, and the sound is
muted. If you still want to view the TV
channel, follow the description “BLUE
BACK” on page 45 to change the BLUE
BACK function setting to OFF.

Poor picture

• If the Digital terrestrial broadcasting
(DVB-T) picture is unnatural, 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. The picture may appear natural
again.
• If noise (snow) totally blocks out the
picture, there may be a problem with the
aerial or aerial cable. Check the following
to try to solve the problem:
– Have the TV and aerial been connected
properly?
– Has the aerial cable been da maged?
– Is the aerial pointing in the right
direction?
– Is the aerial itself faulty?
• If the TV or aerial suffers interference
from other equipment, stripes or noise
may appear in the picture. Move any
equipment such as an amplifier, personal
computer, or a hair drier, that can cause
interference away from your TV. Or try
moving the TV. If the aerial suffers
interference from a radio tower or high-
voltage wire, please contact your local
dealer.
