Symptoms
Possible Causes
The picture is not sharp or the
picture contains image
movement.
• The reception may be weak.
• Change programs to confirm if the symptom is still
present.
• Make sure the outside antenna is not disconnected.
• Make sure the antenna is facing the right direction.
If the antenna is exterior, have a suitable qualified and
experienced antenna specialist adjust the antenna.
The picture is doubled or tripled
• Make sure the antenna is facing the right direction.
• Picture ghosting is caused by reflections from buildings,
large metal structures and mountains. Carefully realign
your antenna to minimise the ghost images. Ultimately a
higher quality antenna professionally installed may be
necessary to reduce the ghosting.
The picture is spotted
• There may be interference from automobiles, trains, high
voltage lines, neon lights, etc.
• There may be interference between the antenna cable and
power cable. Try positioning them further apart.
There are stripes on the screen or
colours faded
• Is the display receiving interference from other devices?
Transmission antennas of radio broadcasting stations and
transmission antennas of amateur radios and cellular
phones may also cause interference.
• Use the display as far away as possible from devices that
may cause possible interference.
