So I was watching Sherlock Holmes (Game Of Shadows) last night on Blu-Ray and the lip sync (sound after picture) was really bad!! So I pulled up the menu on my AVR (Denon 591) and adjusted the delay to the max (200ms) and it was a little better, but still off. So I grabbed my Watchman Blu-Ray and put that in (i have always had issues with the lip sync on that disc) and it was just as bad. So I went into the service menu on my TV (Samsung LN55B650) and went to the sound menu and started setting things to 0.........EXCEPT I FORGOT TO TAKE PICTURES BEFORE I CHANGED THE SETTINGS..........SO NOW IT IS REALLY SCREWED IT UP!!! Here is what I did (all the locations that show 0 were from me....i didn't mess with the other ones) So if anyone has the Samsung LN55B650 and there willing to give me the factory setting, I would be forever in your debt!!! The craziest thing about this whole thing is, there is no lip sync problems on DVD or from my cable box.....only on some Blu-Ray disc's and only when watching Blu-Ray and its starting to get very old. It all started happening about a 8 months after there current TV firmware upgrade and my TV won't let me replace the new firmware with the old firmware. Anyways, if anyone could help me out here I would really appreciate it!!
