I have a LG 42LA6200 smart TV. It is connected to a bose system via optical cable . The sound and picture do not link. Help.

If you mean that you want the sound and picture to be in sync with each other then check the menu of the Bose system and turn off any processing that would cause a delay. Check in the owners manual and with Bose tech support.
