Digital terrestrial broadcasting (DVB-T) service area
Although this TV can receive both Digital terrestrial broadcasting (DVB-T) and Analogue terrestrial
broadcasting, depending on the area in which you live, you may not be able to receive Digital
terrestrial broadcasting (DVB-T).
For details of the Digital terrestrial broadcasting (DVB-T) service area, refer to the FREEVIEW
website etc.
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 mains plug connected to the mains
outlet?
• 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 52 to change the BLUE
BACK function setting to OFF.
• If the SYSTEM setting for a TV channel
is incorrect, it may prevent the sound
from being issued. Follow the description
"EDIT/MANUAL (Analogue)" on
page 53 to use the MANUAL function to
try to change the SYSTEM setting.
Poor picture
• If the Digital terrestrial broadcasting
(DVB-T) picture is unnatural, press the
TV/AV button and MENU/OK button at
the same time. The power will turn off
and then on again, after which 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 damaged?
– 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.
