Troubleshooting
Reception disturbances
Most types of TV interference can be resolve by adjusting the height and position of the VHF/UHF antenna.
Outdoor antennas are recommended for best results. The most common types of TV interference are shown
below. If one of these symptoms occurs when the unit is connected to a cable TV system, the disturbance may be
caused by the local cable TV company broadcast.
Care and maintenance
• To prevent fire or shock hazard, ALWAYS disconnect the unit from the power source before cleaning the unit.
• Wipe the display panel surface gently using only a soft cloth (supplied.) A hard cloth may damage the surface
of the panel.
• Avoid contact with alcohol, thinner, benzene, acidic or and alkaline solvent cleaners, abrasive cleaners, or
chemical cloths, which may damage the surface.
• Never spray volatile compounds such as insecticide on the cabinet. Such products may damage or discolour the
cabinet.
Ignition
Black spots or horizontal streaks
may appear, the picture may flutter
or drift. Usually caused by
interference from automobile ignition
systems, neon lamps or AC powered
tools and appliances such as drills or
hair dryers.
Snow
If the unit is located far from the TV
station, in a fringe reception area
where the signal is weak, small dots
may appear in the picture.
Ghost
Ghosts are caused by the TV signal
following two paths. One is the direct
path and the other is reflected by tall
buildings, hills or other large objects.
Changing the direction or position of
the antenna may improve the
reception.
Radio frequency
interference
(RFI)
RFI is caused by two-way radios.
This type of interference produces
moving ripples or diagonal streaks in
the picture. Some cases may
cause a loss of contrast in the
picture. Changing the direction and
position of the antenna or installing
an RFI filter may improve the
picture.
