Broadcast signal receiving apparatus and method of controlling thereof

A method of controlling a broadcast signal receiving apparatus, comprising:

• determining whether or not a voltage drop of a detection pin occurs by detecting the voltage drop of the detection pin;
• determining that an antenna cable is connected to an antenna connection terminal comprising the detection pin and a signal receiving pin for receiving a broadcast signal from an RF signal pin located inside the antenna cable, when the voltage drop of the detection pin occurs;
• and
• activating and displaying an object indicating that the antenna cable is connected to the antenna connection terminal on a display, when the antenna cable is determined to be connected to the antenna connection terminal, wherein
• at least a part of the detection pin of the antenna connection terminal protrudes outward through an opening formed in a body of the antenna connection terminal in a first direction,
• a voltage of the detection pin drops to ground voltage when at least the part of the detection pin protruding outward through the opening formed in the body of the antenna connection terminal contacts an inner circumferential surface of an antenna cable connector,
• the antenna cable connector is configured to be inserted into the body of the antenna connection terminal in second direction, the second direction being perpendicular to the first direction, and
• the signal receiving pin is configured to be connected with the RF signal pin inserted into the body of the antenna connection terminal in the second direction.
