remote control sensor window.
• Check that the remote control sensor window is not under
strong fluorescent lighting.
• Check for any devices (PC or personal digital assistant,
PDA) nearby that transmit infrared signal which may cause
interference to signal transmission between the remote
control and the TV. Turn off the infrared function of these
devices.

• 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.

• Is the TV 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 TV as far away as possible from devices that may
cause possible interference.
