A:Answer The channel scan is the only way to find any channels that are being fed into the TV. If you used cable equipment on a previous TV in this location, you will need to use the same cable equipment to get the same channels from your cable. If it is an antenna, make sure to place the antenna as high in the room as possible. Feel free to call our call center for assistance any day of the week, from 8 am to 9 pm CST, at 1-877-467-4289.
