Troubleshooting (VHF / UHF reception)

The most common types of television interference are as follows:
SNOWY PICTURE
Snowy picture is usually due to weak signal. Adjust antenna or install an antenna amplifier.
DOUBLE IMAGE OR GHOSTS
Double images are usually caused by reflections from tall buildings. Adjust the direction of the antenna or
raise it.
RADIO WAVE INTERFERENCE
Wavy patterns are moving on the screen, which are usually caused by nearby radio transmitters or short-
wave receiving equipment.
HIGH TEMPERATURE ELECTROTHERMAL INTERFERENCE
Diagonal or herringbone patterns appear on the screen or part of picture is missing. This is probably caused
by high temperature electrothermal equipment in a nearby hospital.
NOTE:If one of these symptoms appears on the screen when the cable from a cable provider is connected,
this may be due to the local cable company broadcast.
