Rated 5 out of 5 by from Great! My husband and I bought this right after the birth of my son over a year ago (much to my displeasure.) Boy was I surprised! This soundbar adds so much more volume to our living room. It feels like you are experiencing what your watching, not just hearing it. Bravo LG!

Rated 1 out of 5 by from It Blocks TV's Infrared Receiver The sound quality is good. But, When put it front of my 47lb652v TV it blocks the TV's infrared receiver. I had to put it behind the TV. Not a great design.

Hi after moving house my nb2540 soundbar isn't working, I suspect the optical audio cable is the problem as power is OK etc, can I buy a new cable? 

Asked by: Mariapatricia
I've had the same problem myself and the easiest solution would be to  stop on your way home from work at Radio Shack.

The remote for this product used to control my tv as well as the sound bar but has since stopped working. Is there a way to reprogram it so it will control the tv again?

Asked by: Chris1031
Thanks for asking, however the remote was not designed for reprogramming. Therefore it would be in your best interest to come see us for an upgrade.

This soundbar never seemed quite right...but especially with the remote that came with it. Now, it won't respond to the remote at all...yes, I changed the batteries. Does anyone know how to reprogram the remote?

Asked by: carlabree1
We regret the inconvenience you have experienced with this Sound Bar system. The remote control is not designed to be programmable for its own player. As such, if the remote control does not operate, and the batteries are not the cause, then the remote control may need to be replaced, or the system may require service. Please contact our Customer Interactive Center at 800-243-0000 for assistance in this matter.
