Abstract
Temperature-rise detecting device and average beam current restricting device operable in response to the former device are provided in television receiver set. Temperature in the television receiver may be kept below a predetermined temperature by reducing the average beam current when the temperature in the television receiver set rises. This results in the lowering of the maximum rated temperature for the parts used in the fly-back transformer, the high voltage rectifier, etc.
