1. Turn off any electrical or battery-operated devices that may be creating radio frequency (RF) interference
   
2. If using an antenna, broadcast signals are reflected by nearby mountain or surrounding tall buildings and may cause ghosting in the picture.
   It is recommended to adjust the antenna direction and location.
   
3. Try plugging the power cord into a different electrical outlet and/or surge protector.
   These symptoms can occur if the electrical outlet is improperly wired or not producing the proper voltage. If using a surge protector or extension cord, it also could be faulty.
