Check if the antenna is broken.  
Picture has “snow”.  
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.)
