You need a remote. There are places that sell them, but you can usually get by with your cable box remote or some other modestly programmable remote. It would help if you had an owner's manual. You can probably find one on line. It is a bit of a dance to make the menus work correctly. 
My set is gone, but you have fairly ordinary on-screen menus. One of them is for sound on or sound off to the internals. That so that there isn't the conflict between speakers from a receiver based audio setup. You should have external speaker outlets on the set itself. If you do, plut in a speaker you're not worried about. you should get sound out from there.or use an audio out connection to a receiver, etc.
