I am having audio sync problem when playing video files through the TV USB port on the LG 47LM6700. Videos are in RMVB format.
I have another LG TV, 39LN5400. Strangely, this TV did not have the audio sync problem.
One thing to note. The software ver. on the TV is 04.30.11. LG Singapore website listed the latest software as 04.20.11. Try to install the older version, but the TV does not allow installation of older firmware. Not sure whether this is the cause.
Any bros facing audio sync issue on LG TVs? Any advice could be appreciated. Will give the local LG a call next week.
