In a television having a memory storing a plurality of central frequencies of channels, a method for scanning a single video carrier channel includes: (A) entering a channel; (B) providing a frequency correction, which is set to zero in initialization; (C) reading a central frequency of the channel from the memory as a target frequency of the channel; (D) determining if a TV channel exists at the target frequency; recording the target frequency as a frequency of the channel when the TV channel exists, and otherwise executing step (E); (E) adding a predetermined frequency difference to the frequency correction to thereby obtain an updated frequency correction; (F) setting the target frequency to a value of the central frequency plus or minus the updated frequency correction when the updated frequency correction is not greater than a predetermined frequency bound, and executing step (D).
