Picture regularly breaks up on
some channels, or
“No Signal” message
•
Check “Signal Display”. (p. 25)
If “Signal Quality” or “Signal Strength” are displayed in red or
constantly changing, check aerial.
If problem persists consult your local TV aerial installer.
•
Check that the aerial and antenna cable are designed for DVB.
For your safety, the aerial and cable should be inspected / installed by a
licenced installer that should comply with Australian Standard AS1417.1.
•
Interference (known as impulse noise) from household appliances
such as light switches, fridges etc may cause picture break up and /
or audio distortion. Use high quality quad shielded coaxial cable fl y
lead between TV and antenna wall socket to minimise impulse noise
pickup. If problem persists consult your local TV aerial installer.
•
When “No Signal” message is displayed check TV aerial connection.
•
The received signal may be too weak to allow the TV to reliably lock to the
desired “No Signal” channel to generate a stable picture. Repeat the tuning
procedure (p. 24). If problem persists consult your local TV aerial installer.
TV takes so long to turn on
•
Like your computer, the TV has to run a number of diagnostic and
software checks before it can display any broadcast channels.
The channel cannot be changed
•
Is the TV in Teletext mode? (p. 16)

•
Are the batteries installed correctly? (p. 6)
•
Has the TV been switched On?
Picture very infrequently
breaks up on some or all
channels
•
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.
•
Impulse noise interference from an infrequently used electrical appliance,
or a passing vehicle or lawn mower with a “noisy” ignition system.
After DVB Auto Tuning only
some or no DVB channels are
found
•
Check to ensure your area is covered by DVB transmissions.
(www.dba.org.au/)
•
Check that the aerial and antenna cable are designed for DVB.
For your safety, the aerial and cable should be inspected / installed by a
licenced installer that should comply with Australian Standard AS1417.1.
Note: If you live within 5-10 Km of DVB transmission towers, a
combined VHF / UHF aerial should be adequate. Outside this area,
separate VHF and UHF aerials provide superior reception performance.
•
If you live in a unit or apartment, check to ensure the Master
Antenna TV (MATV) system is designed for analogue and DVB-T
reception. Please consult your body corporate. (www.dba.org.au/)
DVB
•
Digital TV reception technology requires high quality, robust DTV signals which in some domestic aerial
installations, may be relatively poor despite good analogue reception.

Permanently lit spots on
screen
•
Due to production process involved in this
technology this may result in some pixels which are
permanently lit or unlit. This is not a malfunction.
Contrast is reduced
•
Contrast is lowered when the following conditions
without any user operation for a few minutes:
Ɣ
no signal in DVB or AV mode
