Troubleshooting
• Check whether you have selected Mute for Audio setting.
• Make sure the volume is not set to minimum.
• Check the AV cables for disconnection.
• The reception may be weak.
• Change channels 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.
• 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.
• Is the television 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 television as far away as possible from devices that
may cause possible interference.
