My tv will not show in 1080i. According to my cablebox, it is in 720 mode and the screen is showing white snow. Can you help me get it back to 1080i mode?
You need to add a lot more info here, or just contact your cable company. Is the TV a 1080i one? Are you sure you have the right input selected? You said "BACK to 1080i", what happened to change it?
