●
Check "Signal Condition" via TV Setup menu. If "Signal
Quality" or "Signal Strength" are 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.
●
Off Timer function is activated.
●
Auto power stanby function is activated.
●
The TV enters Standby mode about 30 mins. after analogue
broadcasting ends.
●
Are the batteries installed correctly? (p. 3)
●
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.
