House struck by lightning and blew out TV and Surround Sound system. Purchased and installed new TV with Sonos sound bar. Have random and intermittent issue with audio out of sync with picture. All Verizon hardware has been replaced and have tried multiple audio setting fixes with TV. Any help?
Get into box service menu: power off at box, OK2x, left arrow, user menu, scroll to additional HDMI settings, look at audio delay. If it's on auto, try 150, hit ok. Restart box. If video is still behind audio increase delay value. If you don't have Fios one box, menu is: power off at box, then OK, Menu quickly. Then scroll to additional HDMI settings. Same after that. If that doesn't work, tell me how you have TV and soundbar hooked up.
