TV interference is a common problem that can occur when watching television. It is caused by external signals, such as radio waves, interfering with the TV signal. The two most common forms of TV interference are STATIC and SNOW. STATIC is a type of interference that appears as a series of dots or lines on the screen. SNOW is a type of interference that appears as white or gray specks on the screen. Both STATIC and SNOW can be caused by a variety of sources, including electrical equipment, power lines, and even weather conditions.
