What People Are Saying

Rated 5 out of 5 by from Great Sound I purchased the sound bar 2 weeks ago and the sound experience has been great so far. The sound quality reminds me of being in a movie theater. I was easy to configure the bar and by LG tv together to work as one.

Rated 3 out of 5 by from Better then just a sound stand For the price it's a good product I like that the woofer plugs into a outlet. The thing I don't like about products these days are firmware updates..I think the manufacturer should send you a thumb drive with the updates on it! Sometimes the sound goes out I think it may be due to needing a update! It was easy to hook up.

Running this through an optical cable. Every time the bar is on, the audio and video cuts out for brief moments. Tv is an LG 43UJ6200. When I turn the bar off, everything is fine. Will the firmware update solve this issue?

Is my 43LF5400 TV compatible with this sound bar. And if now what is?

Asked by: Tristin
Hi Tristin. The LG 2.1 ch High Resolution Audio Sound Bar, Model # SJ4Y can be paired with a TV that supports Bluetooth for wireless streaming or it can be connected to a TV that has an Optical Digital Audio Output on it or one that has an HDMI Port that Supports HDMI ARC functionality. Regrettably, your LG Full HD 1080p LED TV - 43" Class (42.5" Diag), Model # 43LF5400 is an entry level model that is designed for people who are not looking to add any external audio systems to augment the TVs sound. It does not have any feature that allows you to connect any Sound Bar to it or any other external audio system...^IFV

I have my Soundbar hooked up through the HDMI ARC cable. My Room is not that big. Although sound is good volume is horrible. I have to turn it up to 100 to even get decent volume. Is this to be expected? I would think Max Volume would be very loud.

We may need to do some troubleshooting. Please give us a call when you are with your unit at 1-800-243-0000. ^AC
