Picture & Sound not synchronized

[pilgrim133]

New Sony 57" HDTV. On broadcast television using a TERK TV-55 antenna, what would cause the sound to preceed the video?

Is this on an analog or digital station.  It should be syncronized perfectly either way unless you caught a bad show that was out of sync.  Are you using on-board audio on the set or an external receiver/amp?  This could also create a processing problem, however I don't have any problems like that.  If it happens all the time, I'd check my manual and do a hard reset.  *usually means unplugging the unit for 15 minutes and then reinitializing it*

The over reason can be in you are using a set tob box to feed a TiVo and then feed the TiVo picture to the TV, but route digital sound from the STB direct to an amp or TV.

TiVo delays the picture, so the sound would be ahead by about 1 to 1 1/2 seconds.

You're probably not using TiVo, but it is one possible reasons

Another possibility is you are hearing the analog channel's audio, while watching the digital channel's video.  That might happen if you have your amplifier set to "TV" instead of "DSS" or whatever you use for your digital sound.  The analog channel precedes the digital -- I assume its due to digital processing delays along the path, both local to and remote from your set.
