A:AnswerI think there is no way to keep a channel from previous scan without loosing it on new scan. I am also looking for a TV that would do this - for those of us in rural areas with stations in different directions the only option is to have multiple antennas pointed in different directions for scan or to take TV to somewhere it can scan all stations in and then bring it back home.
