What people are saying

Rated 3 out of 5 by from It’s great when it works I am a die hard LG fan. Have purchased many TV’s, laptops, fridges, and audio products. Have been super happy up until now. This product was great for the few months. A repair has been attempted but failed. Support is refusing to replace the product. Not happy with the support on this one.

Rated 1 out of 5 by from Garbage Bought this from Best Buy in 10/20 Subwoofer started cutting in and out and now will not connect at all-exactly 1 month after warranty expired. Customer service line disconnects while waiting. Don’t waste your money

Rated 1 out of 5 by from When it works it’s awsome The sub disconnects randomly, sometimes over and over, it’s very frustrating when you are into your show, I’m trying to go through LG costumer service to get it fixed or replaced, I think I will forever have a wired sub for now on

Can I update software for LG SN8YG? How do I do it? Update software for Google Assistant on same unit? How do I do it? Can't find anything in the manual or online. All software has bugs. I like to keep my equipment updated.

Asked by: Don22
If or when any firmware updates become available for the LG SN8YG 3.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Google Assistant Built-In, you will have to visit the support page for the Soundbar on our site and download the update on a thumb drive that you can then insert into the USB drive on the Soundbar to install the update. Google Assistant firmware updates are from Google LLC and you can check for any available updates when or if they are available through the Google Home app or check through Google's official site...^Ivan

Suddenly my subwoofer stopped turning on. It currently gets no power. The soundbar still works but there is no bass as the subwoofer will not power on. Anyone have any ideas? Do they sell the subwoofer separately?

Asked by: JJW51
Try unplugging the Subwoofer for the LG SN8YG 3.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Google Assistant Built-In and plugging it back in to see if that resolves the issue. If it is still not receiving power, check the outlet that it is plugged into to ensure that the outlet is working. You can use a lamp or something else to plug into the outlet to check if it is working or not. You may also want to make sure that the circuit breaker for that outlet hasn't tripped. You can contact our LG Authorized Parts Distributor Affiliate, Encompass Simply Parts, (800) 432-8542, to inquire if the Subwoofer can be purchased separately...^Ivan

re: LG UHG AI Thin Q 86" I want a sound bar that is proper for TV. We do not get to carried away with electronics. Which LG bar? we have a comcast system and do not want to use more than the controller. Just want on with TV, Net Flex, Apple TV etc.

Asked by: BSCparts
What is the model number for the LG 86 inch 4K Smart UHD TV w/ AI ThinQ® that you are looking for s suitable Soundbar for? Any of our Soundbars will work with any of our TVs, but some TVs have features on them that are best matched up with a suitable Soundbar for you to get the most out of the available feature on both the Soundbar and the TV. The specifications for our Soundbars under DIMENSIONS/WEIGHTS have a TV Matching spec that lets you know if the Soundbar is suitable for a screen size of more than 49" so the soundbar is an aesthetic match for the TV, but knowing which model number the TV is also helps to help us give recommendations on which Soundbar best suits the TV. As for features on the Soundbar, you will need to review the Soundbars to determine which features you are interested in or not interested in. You also need to keep in mind that TV, NetFlix or Apple TV also stream audio in different audio formats so if you want the best audio experience while watching TV programming or movies from NetFix or Apple TV, you will need a Soundbar that is capable of supporting the audio format that is being streamed through them...^Ivan

I just ordered a 65" nano tv. Will the SN8YG cancell out the tv speakers or will it work together?

Asked by: Mesa5050
Which 65" LG NanoCell TV model do you have, the Nano 99, Nano91, Nano 91, Nano 90, Nano 85, or Nano 81 series TV? When the LG SN8YG 3.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Google Assistant Built-In is connected to the TVs via the Optical Digital Audio port, you can use the TV's internal speakers and the Soundbar simultaneously. The TV's internal speakers and audio outputs are only disabled when streaming audio to Bluetooth headphones or Bluetooth speakers...^IFV
