Some problems will only occur when viewing DVB channels. Due to the different techniques involved in digital
reception, DVB signal quality
 
can be poor even if you appear to have a strong signal
 
when viewing analogue
programmes.
The DVB system requires a good quality signal to provide the best picture. When viewing analogue pictures,
interference such as signal reflection from nearby buildings or mountains causes ‘ghosting’, but still provides a
viewable picture. For the DVB system, interference such as this can disrupt the flow of data causing the picture to
appear to be made up of large blocks, or to freeze intermittently. If the picture disappears completely, this could
mean that signal quality is very poor. If this happens often, you may need to improve your aerial system to provide
a better signal. This TV contains a complex microprocessor which enables you to view enhanced digital services.
Occasionally this device may need to be reset. This can be done by pressing the standby button on your remote
control.
Symptoms
No DVB channels listed in the
TV Guide after Auto Setup.
Blocky interference.
Picture freezes intermittently.
I have a good aerial system, but still cannot receive
DVB stations.
Checks
Check that DVB transmissions are available from the transmitter
you are currently using. If not, try directing the aerial at another local
transmitter.
Check analogue transmissions. If picture quality is poor, you will
need to improve or change your aerial system to receive DVB
channels. Consult a local installer.
Blocky interference indicates that the signal quality is poor.
You should consider improving your aerial system.
To check the quality of your signal use the Signal Quality feature
(see page 26).
Good quality signal – indication is green.
Poor quality signal – indication is red.
If you have tried the previous solutions and are still
unable to receive DVB channels, you may need to
provide dedicated aerial feeds to the TV and other
equipment.
This can be implemented using an
aerial splitter or separate aerials.
