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 re
fl
ection from nearby buildings or mountains causes ‘ghosting’, but still provides a viewable picture.
For the DVB system, interference such as this can disrupt the
fl
ow 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
Checks
No DVB channels listed after Auto Setup.
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.
Picture freezes intermittently.
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 19).
Good quality signal – indication is green.
Poor quality signal – indication is red.
I have a good aerial system, but still cannot receive
DVB stations.
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.
