What people are saying

Rated 1 out of 5 by from Very unreliable I have owned this LG soundbar for 2 years, for the last year I dealt with the subwoofer sound constantly cutting in and out. Now the sound for the whole unit just goes out. The only way I figured out how to get it going again is to unplug and plug the optical cable back in. I will be replacing this unit soon, and it definitely won't be another LG...

Rated 4 out of 5 by from Sounds amazing Bought a month ago and have to say impressed by the sound of a not very expensive sound bar combo. Good bass and good treble.

Rated 2 out of 5 by from good sound, intermittent sub connectivity We have 2 LG TVs in the house and soundbars. This was the last piece I got and have given me pause about LG. The subwoofer intermittently disconnects which is very distracting. I’ve tried all the troubleshooting, to no avail. It’s sitting just feet below the soundbar which is attached to the underside of the tv. No other electronics between the two. I’ve been hoping for a firmware update but have given up hope of that.

Why is my sound bar causing interference on my TV. When the sound bar is on the tv constantly scrambles. When I turn it off the signal is fine without scrambling.

Do I need to purchase an hdmi cord to install this model??

Asked by: JCampbell9
Hi JCampbell9. We are not clear on your inquiry about if an HDMI cable is required to install the LG 2.1 ch High Resolution Audio Sound Bar, Model # SJ4Y-S. The unit does not need installation. It has an HDMI IN, HMDI Our (ARC), an Optical Digital Audio Input and a 3.5 mm (Portable IN) port, all of which can be used to connect to devices that have compatible ports to connect to so you can play their audio through the Sound Bar. It also has Bluetooth Connectivity so it can be paired to a Bluetooth enabled device so you can stream audio from such a device wirelessly to the Sound Bar...^IFV
