A television having a program rating function according to a set-up value of a program rating set up by a user and a method for controlling the same. The television has: a judgment unit for judging the program rating based on a program rating signal included in a received broadcasting signal; a set-up value storage unit for storing the set-up value of a program rating set up by the user; a display unit for displaying the program rating judged by the judgment unit; and a control unit for controlling the display unit to display the program rating judged by the judgment unit, when there is no set-up value in the set-up value storage unit. Therefore, when the programs are broadcasted in a situation in which the user has not set up the set-up value of the program rating due to the inconvenience of a V-chip (Violence-Chip), it is reported to the user that the television includes the above function through a display unit.
