Game runs but the game wont come n the tv

Have you tried a different cable. If a new cable did not work then its more likely the connector its self and would have to be re-solderer to be fixed. I would add some hot glue around the connector for more support but make sure it still has clearance in the case for proper fit. You could also try to clean the connector and cable with some rubbing alcohol. do not soak them. Use something damp. If nether of them work then the mother board is fried.
