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.

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.
