Troubleshooting guide
Picture regularly breaks up on some channels.
“No signal” message is displayed.
¾ Check aerial connection.
¾ Check that the satellite dish and satellite cable are designed for
DVB.
¾ Check “Signal Condition”. If “Signal Quality” or “Signal Strength”
are displayed in red or constantly changing, check aerial. If
problem persists consult your local TV aerial installer. (
> 88)
¾ Interference (known as impulse noise) from household
appliances such as light switches, fridges etc. may cause
picture break up and/or audio distortion. Use a high quality
quad shielded coaxial cable fly lead between this unit and
antenna wall socket to minimise impulse noise pickup. If
problem persists consult your local TV aerial installer.
¾ Check the reception capacity of the satellite dish. The dish must
be large enough for good reception. There must not be any
hindrances in the way which could impair reception, e.g. twigs,
leaves, snow.
¾ Adjust the aerial reception with “Manual Tuning” in the Setup
menu. ( > 88)
¾ The receiver (LNB) of the satellite dish must be suitable for
digital reception.
Picture very infrequently breaks up on some or
all channels.
¾ Electrical atmospheric interference caused by local or distant
lighting storms or heavy rain with wind in “leafy” locations may
cause pictures to break up and audio to mute or distort
momentarily.
¾ Impulse noise interference from an infrequently used electrical
appliance, or a passing vehicle or lawn mower with a “noisy”
ignition system.
¾ The reception capacity of the satellite dish is not sufficient.
After the Auto-setup, there aren’t any stations in
the station list.
