How do I adjust the sound sync on my TV?

Does the TV have its own audio sync setting? Mine allows for positive or negative audio delay.

It doesn't have audio sync settings, not that I can find.

Our DVD player had an audio +/- option under the audio setting panel when you went into the "setup" options. You could advance or retard the audio. I don't know if Roku players offer that, though it's possible it might be a setting in the Netflix or Hulu player itself.

Weird that it's doing it with internal speakers. Quick searches reveal the following: - http://www.amazon.com/LG-47LH40-47-Inch-1080p-Gloss/product-reviews/B001VKYAKE/ref=cm_cr_dp_synop?ie=UTF8&showViewpoints=0&sortBy=bySubmissionDateDescending#R2CVD2NLKJR81Chttp://www.amazon.com/review/R3GC3OY2JK5F1J/ref=cm_cr_dp_title?ie=UTF8&ASIN=B001VKYAKE&nodeID=172282&store=electronics time that needs to pass. But this seems... strange to me - a search through AVS Forums didn't turn anything up, but you might have better luck. Questions I've gotta ask: - if everything is disconnected from the TV, is the sound from the TV's speakers in sync with what's on screen? - how, exactly, are all of your components connected? That is, what cables are used and where are they going? - would you clarify how things are out of sync, and if it's consistent? That is, is the audio ALWAYS delayed, or is it always such that the picture ALWAYS seems delayed? How does changing the delay on the sound bar affect sync (what are the settings, and as they're increased/decreased, how is the audio/video sync affected)? - do you have a TruMotion option? Does turning it on/off change things? If so, how? - do you have a Game Mode picture option? Does turning it on/off change things? If so, how? Speaking from personal experience, I wish you much luck and minimum frustration. In the end, my AV sync options got fixed with newer HDMI cables, and throwing ALL video sources to a receiver, and a single HDMI cable to the TV. Doesn't look like your sound bar has that many HDMI inputs though.

Hey, I noticed that on Whose Line too! It was bad on SD, tolerable on HD, and unwatchable on Youtube.

I too was going to mention resetting the TV to factory settings, and then if that doesn't help, setting it to video game mode. I'd bet that the TV is overdoing it with some kind of visual processing. The fact that it happens on SD (dvd and sd Whose Line Is It Anyway) leads me to believe this is true. "Smart" TVs will try to clean up SD signals to make them look a little nicer on the giant screen. Video game mode (is supposed to) shut all that stuff down.

Thanks for all the suggestions. Sitting here watching a DVD of Spartacus, I'm trying: TruMotion I turned it off and I think it made the sync worse, so I set it back to "low." Picture Mode: switched to "Intelligent Sensor," and that seems to have helped -- which is weird, I would think that would make it worse, but it's been the best option so far. Real Cinema: turning it off might have it worse, so I turned it back on. Various AV Mode settings: Cinema might be better, Sport might be worse, Game might be worse. I left it off. Watching an episode of "Elementary," on the Tivo, recorded in HD, the sync is bad with the above settings. "Whose Line" is badly synced in Game Mode or not, but it sounds like that might not be just my TV. An episode of "Inspector Morse," Tivo'd in SD, made me realize all those hideous clothes are back in style but also the sync seemed fine. I can't see how everything is plugged in right now (it's a two-person job and I'm the only person free right this sec because nobody else appreciates how awful this situation is) but I'll investigate ASAP. https://ask.metafilter.com/247243/How-do-I-adjust-the-sound-sync-on-my-TV#3591011 would you clarify how things are out of sync, and if it's consistent? That is, is the audio ALWAYS delayed, or is it always such that the picture ALWAYS seems delayed The audio always seems delayed. It's worse on some shows than others. This might be because some shows have more time when you see the people talking; if I can't see the person's lips, it isn't a problem. But "Spartacus" has been particularly bad. It could be that DVDs are bad in general and I hadn't noticed because I don't use the DVD player much, and when I do it's usually for kids' animated movies where it wouldn't matter.

A couple of suggestions: one--have you tried updating the firmware? two--have you tried doing a hard reset (or "factory reset") on the TV (there should be instruction in the manual)?

Wow, I didn't even consider that the audio would be delayed. I just assumed that the video would be the thing. All my advice is wrong, in that case. I would start by eliminating the sound bar. Unplug it. Same thing with any other switchers, combiners, etc in the process. Yes, this will be a pain. Then, proceed to check whether the problem can be narrowed down to one type of input or another. If you can get your hands on an older television, try plugging the different sources into it and comparing the results. This will help prove that the problem is or isn't the LG tv. And have you read the manual for the TV cover to cover? When all else fails.... (Seriously though, many AV appliance manuals are terrible. A really important thing can often be buried in plain sight.)
