control unit.
Check there are no obstacles between the sensor window and remote control
unit.

All channels lose color
Intermittently
Check if the antenna is broken.
Check if the antenna is disconnected.
Check if the antenna is damaged.
Poor reception, loss of
color with certain
channels
Check if channels are correctly tuned.
Diagonal stripes appear
on picture
The receiver may be affected by interference (e.g. from nearby radio
broadcasting transmitter or from another TV receiver).
Picture has ‘snow’
Check if the antenna is broken.
Check if the antenna is disconnected.
Check if the antenna is damaged.
Ghost images appear
Check if the antenna direction has been changed by a storm or strong wind,
etc. (because ghost images are caused by the arrival at the antenna of both
the signal which has traveled directly from the transmitter and the signal
which has been reflected from a hill or a large building. The direction of the
antenna should be chosen for minimized ghosting.)
