•
Check [Signal Condition] via TV Setup menu. If [Signal Quality] or
[Signal Strength] 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,
try 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 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 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.
•
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.
•
Auto power standby function is activated.
•
The TV enters Standby mode about 30 minutes after analogue
broadcasting ends.
•
Are the batteries installed correctly?
•
Has the TV been switched On?
•
Point the remote control directly at the front of the TV (within about
7 m and a 30 degree angle of the front of the TV).
•
Situate the TV away from sunshine or other sources of bright light not
to shine on the TV's remote control signal receiver.
•
Even when the temperature of parts of the front, top and rear panels
has risen, these temperature rises will not pose any problems in
terms of performance or quality.
