Poor QualityI’ve had the sound bar with the sub woofer for a little over a year, the sub woofer just died. I contacted LG and they said it’s out of warranty and there is nothing they can do. They offer to forward repair company us close to me. I’m not interested in items like this that don’t last, especially with low to moderate use. It was good until for about a year or so. Too bad the quality is not too good. I also have other LG products, now I’m worried about them. If the customer service was better, and the quality, I would have more confidence.

Disappointed Subwoofer Had To Be RepairedInitially very much liked the sound of this soundbar and subwoofer. I did find operating with a smart tv more difficult than it should have been. Being this was a collaboration with Meridian Electronics, I expected a higher quality of product. Was disappointed that after two years with limited usage, the subwoofer quit working as noted in several forums by other owners. Unfortunately for me it was no longer covered by warranty and proved to be quite costly to repair although I understand from forum members who repaired their own subwoofers that the replacement part, was not terribly expensive nor hard to replace when you could find the replacement circuit card. The effort to get it to the repair facility in California proved to be more difficult than it should have been and the expense for packaging to avoid damage while shipping proved to be substantial. I was promised by LG representatives from overseas that I would be reimbursed, but I feel it would take much effort on my part to recover my money and much longer on the phone trying to get someone from another country to try and understand me than I am willing to invest at this point. I like the way the system sounds when it works but find myself wondering how long it will continue to work. On a scale from 1 to 10, I’d give the SN8YG Sound bar and Subwoofer a solid 9 on sound but a disappointing 2 on quality and dependability. The only positive for me was the quick turnaround from the repair facility in California back to me in about a weeks time. Good job LG repair facility!

Great sound.. but subwoofer disconnects.After a few months my subwoofer started to randomly disconnect for a few seconds, and now it has completely shut off, and I need to reboot the entire system before it starts working again. Is there a way to fix the subwoofer issue? I really love the design and the sound output, but I can't live with it not working..

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, https://encompass.com 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
