The invention provides a priority selector for external signals having a tri-mode converting circuit with a switching part, wherein a TV signal or external signals are selected by operating a converting switch of the switching integrated circuit in response to fast blanking (F/B) signal, and a priority-giving part, wherein one of the external signals is selected by converting the converting switch of the switching integrated circuit in response to the fast blanking (F/B) signal. Simplifying the circuit may be possible since the priority is given by the switching voltage, and reducing the cost of the product and improving the quality of the product may be attained.
