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 /
distort momentarily.
Impulse noise interference from an infrequently used electrical appliance,
●
or a passing vehicle or lawn mower with a "noisy" ignition system.
Older style antenna cabling, loose fitting/corroded wall socket connections
●
/ terminals etc.
Picture regularly pixelates on some channels, or
Check Signal Condition
●
Strength is red/orange or constantly changing, check aerial/cable/
connections. If the problem persists, consult your local TV antenna
installer.
Too much signal; is
●
attenuating (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 the
●
selected channel to generate a viewable picture. If the problem persists,
consult your local TV aerial installer.
Interference from household appliances (known as impulse noise) such
●
as light switches, fridges etc. may cause picture break up and / or audio
distortion. Use high quality quad shielded coaxial cable (RG6Q) fly lead
between TV and antenna wall socket to minimise impulse noise pickup. If
the problem persists, consult your local TV aerial installer.
Antenna installation may be using an aerial amplifier that is faulty or an
●
older style 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 Mains power On / Off switch, then turn it On again.
●
= Note =
Digital TV reception is only as good as the antenna and the antenna cabling
delivering the DTV signals to the television. Reliable digital TV reception
requires high quality, robust DTV signals which can only be achieved when
using a TV antenna and cabling designed for digital TV reception.
