Some HDTVs have special video processing enhancements, such as Digital Natural Motion and Noise Reduction, that can slightly delay the video causing the audio and video to be out of sync. The sync problem also may be caused by the distance of the speakers from your listening position.

To correct the audio sync problem you can disable the special video processing enhancements on your TV set and/or adjust the speaker distance setting on the home theater.

Set the number of milliseconds you need for the delay. Ask yourself how far away the speakers are from you while you are watch the TV? Allow 1ms setting for every 1 foot distance between the speaker and the listening position. Set a longer delay time if the center speaker or rear speaker is closer to the listening position than the front speaker.

Note: If you are using a Philips TV that features Digital Natural Motion you may need to disable that feature to stop the audio sync problem. The Digital Natural Motion can create up to 200 milliseconds of lag. The lag is only noticeable if you are using the audio on the Home Theater System and not the TV speakers.
