DVB Troubleshooting

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.

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 23).
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.
