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.
Symptom
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.

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.

Checks
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 Condition
feature (see page 35).
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.
