I have two LG LCD TVs, one relatively new, the second quite a few years older. Both exhibit temporary audio sync problems when first switching to the channel. The problem usually resolves itself within about 20 seconds, but on one occasion it peristed, on both sets, for two days.
Is this a firmware bug, or is it a transmission anomaly, perhaps due to a weak signal? The video is perfect, and the audio remains in sync until the channel is changed. Sometimes sync can be restored by channel surfing to News 24 from the lower ABC channels.
