FAQs108Problem Causes / ActionsDigital TVConnecting devices suchas DTV recorder / PVR /VCR etc that also requirean antenna connection tothe digital television● To maintain optimum antenna signal quality, use an ‘F’ type TV signal splitter(as illustrated) when connecting two or more devices to the same antennasocket.TVDTV Recorder / PVR / VCROutIn‘F’ type Antenna SplitterAntenna SocketWall PlateRG6Q Fly LeadRG6Q Fly LeadRG6Q Fly Lead● Hint: Some degradation of the DTV signal may occur if you are connecting theaerial through an external device (e.g. DVD Recorder or Set Top Box). Inthis case it is better to use a splitter and connect the aerial directly to bothdevices.After digital TV tuning, (orre-tuning) some or all DTVchannels are missing● Check to ensure your area is covered by DTV transmissions.● Check that the aerial and antenna cable are designed for DTV reception. Ifyou live within 5-10 km of DTV transmission towers, a combined VHF / UHFDigital TV aerial should be adequate. Outside this area, separate VHF and UHFaerials 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 DTV reception. Please consultyour body corporate.Picture infrequentlypixelates on some or allchannels● Electrical interference caused by local or distant lighting storms, heavy rain,high wind etc. may cause picture to break up and or audio to mute / distortmomentarily.● Impulse noise interference from an infrequently used electrical appliance, or apassing vehicle or lawn mower with a “noisy” ignition system.● Older style antenna cabling, loose fitting/corroded wall socket connections /terminals etc.Picture regularly pixelateson some channels, or ‘NoSignal’ message● Check [Signal Condition] via TV Setup menu. If [Signal Quality] or [SignalStrength] is red/orange or constantly changing, check aerial/cable/connections.If problem persists, consult your local TV antenna installer.● Too much signal; is [Signal Strength] always at full strength? If yes, tryattenuating (reducing) the signal strength.● Check that the aerial and antenna cable are designed for DTV reception.● The received signal may be too weak to allow the TV to reliably lock to theselected channel to generate a viewable picture. If problem persists, consultyour local TV aerial installer.● Interference from household appliances (known as impulse noise) such aslight switches, fridges etc. may cause picture break up and / or audio distortion.Use high quality quad shielded coaxial cable (RG6Q) fly lead between TV andantenna wall socket to minimise impulse noise pickup. If problem persists,consult your local TV aerial installer.● Antenna installation may be using an aerial amplifier that is faulty or an olderstyle aerial amplifier that was not designed for digital TV.● Older style antenna cabling, loose fitting / corroded wall socket connections /terminals etc.● Turn the TV off with the Mains power On / Off switch, then turn it On again.NoteDigital TV reception is only as good as the antenna and the antenna cabling delivering the DTV signals to thetelevision. Reliable digital TV reception requires high quality, robust DTV signals which can only be achievedwhen using a TV antenna and cabling designed for digital TV reception.● Further reading please visit: http://www.digitalready.gov.au/publications.aspx where you can download ‘TheDigital TV Antenna Systems for Homes Handbook’ information pdf file. /● For your safety, the antenna and cabling should be inspected / installed by a licensed installer that shouldcomply with Australian Standard AS1417.1 for Domestic installations or AS1367 for MATV installations./
