Please Help: Sony A/V Sync

[rartist]

For the holidays I retired my failing Sony Bravia and treated the family for a 60" Vizio passive 3D LED. The picture and 3D are wonderful, but it became obvious to me that the sound is running fractionally behind the picture. My workflow is a PlayStation 3 and a Cox digital cable box upstream HDMI from a Sony 7.1 receiver (think its a STRDG910, don't have it near by at the mo) with the Vizio HDMI downstream from that.

Is there any way I can tune the sync through the receiver? The Vizio has a sync function but it must be for A/V through the TV because it has no effect.

Thanks for any help, I'm new to this.
