• a front cover;
• a rear cover attached to the front cover to accommodate the display panel, the main PCB, and a PCB supporting member, the rear cover having a tuner unit opening;
• a tuner accommodating part disposed between the PCB supporting member and the rear cover to be coupled to the PCB supporting member, having a housing, a connector opening formed on the housing corresponding to the port opening of the PCB supporting member, and a tuner receiving opening formed on the housing corresponding to the tuner unit opening of the rear cover;
• and
• a TV tuner unit inserted from an outside of the rear cover into the tuner accommodating part through the tuner unit opening of the rear cover and the tuner receiving opening of the tuner accommodating part in an inserting direction, having a casing with an upper opening corresponding to the port opening of the PCB supporting and the connector opening of the tuner accommodating part, a TV tuner contained in the casing, and a connector formed on the TV tuner to protrude from the casing through the upper opening and coupled to the connection port of the main PCB through the connector opening of the tuner accommodating part and the port opening of the PCB supporting member.

A display apparatus receiving a TV tuner unit, comprising:

• a display panel;
• a main printed circuit board (PCB) having a signal processor transmitting a video signal to the display panel and a connection port connected to the signal processor;
• a PCB supporting member supporting the main PCB, and having a port opening receiving the connection port and an earth spring protruding toward the rear cover;
• a front cover;
• a rear cover attached to the front cover to accommodate the display panel, the main PCB, and a PCB supporting member, the rear cover having a tuner unit opening;
• and
• a tuner accommodating part disposed between the PCB supporting member and the rear cover and coupled to the PCB supporting member, having a housing, a connector opening formed on a first side of the housing corresponding to the port opening of the PCB supporting member to receive the connection port, an earth spring through hole formed on a second side of the housing corresponding to the earth spring, and a tuner receiving opening formed on a third side of the housing to receive the TV tuner unit inserted into the housing from an outside of the rear cover through the tuner unit opening of the rear cover in an inserting direction, the connection port of the main PCB and the earth spring of the PCB supporting member both coupled to the TV tuner unit.

A TV tuner unit for a display apparatus, comprising:

• a casing having a first surface and a second surface;
• a tuner PCB contained in the casing;
• a TV tuner contained in the casing and coupled to the tuner PCB to receive a TV signal;
• an earth part formed on the tuner PCB;
• an earth part through hole formed on the first surface of the casing corresponding to the earth part of the TV tuner;
• a connector opening formed on the second surface of the casing;
• a connector formed on the tuner PCB to protrude from the casing through the connector opening;
• and
• a decoder disposed in the tuner PCB and coupled between the TV tuner and the connector to convert the TV signal into a video signal and transmit the video signal to an outside of the TV tuner unit through the connector.

A method in a display apparatus, comprising:

• coupling a main printed circuit board (PCB) having a processor and a connection port to a PCB supporting member having an earth spring and a port opening receiving the connection port of the main PCB;
• coupling the PCB supporting member to a display panel and a front cover;
• coupling a tuner accommodating part having an earth spring through hole, a connector opening, and a tuner receiving opening to the PCB supporting member;
• coupling a rear cover having a tuner unit opening and a pushing part through hole to the front cover to accommodate the display panel, the main PCB, the PCB supporting member between the front cover and the rear cover, the tuner accommodating part disposed between the rear cover and the PCB supporting member;
• inserting a pushing unit from an outside of the rear cover through the pushing part through hole to be movably coupled to the tuner accommodating part;
• inserting a TV tuner unit having a TV tuner, an earth part, and a connector into the tuner accommodating part through the tuner unit opening of the rear cover and the tuner receiving opening of the tuner accommodating part;
• connecting the connector of the TV tuner unit to the connection port of the main PCB through the port opening of the PCB supporting member and the connector opening of the tuner accommodating part;
• connecting the earth spring of the PCB supporting member to the earth part of the TV tuner unit through the earth spring through hole of the tuner accommodating part;
• and
• connecting the pushing part to the TV tuner unit.
