    “..duplicated values in serial_id, season and ep_id.”

    SELECT  serial_id, ep_id, season
FROM    tableName
GROUP   BY serial_id, ep_id, season
HAVING  COUNT(*) > 1

    but if you want to get all columns (*assuming you have other columns except serial_id, ep_id, season*) within the row

    SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT  serial_id, ep_id, season
            FROM    tableName
            GROUP   BY serial_id, ep_id, season
            HAVING  COUNT(*) > 1
        ) b ON  a.serial_id = b.serial_id AND
                a.ep_id = b.ep_id AND
                a.season = b.season
