Rated 1 out of 5 by from Subwoofer didn't last long The system worked okay at first and had better sound than what you would get from no external speakers on your flat screen. Then after just a couple months the subwoofer quit working. It then started working again for a while. It did this several times and finally quit working completely. I'm lot saying the subwoofer wouldn't pair up; it completely quit working. I don't suggest you buy this unit.

My question was taken down? But my sub won't connect to my speaker bar and just flashes green super fast no matter what I do. I've tried unplugging it, as soon as I plug it back in it continues but it won't connect. Don't take my question down this time.

I am having trouble with my LG speaker bar and Sub. My sub will not connect to my speaker bar. It simply flashes green super fast but will not connect no matter how long I wait. And I cannot get my speaker to stop flashing even by unplugging it. 

Asked by: Kyle3
We do apologize about the issue you are having with the Sound Bar System. The green light flickering indicates that the unit is in PAIRING mode. If the green light continues to flicker, even after it is unplugged, the unit may require service. For better assistance with the matter, please contact our Customer Interactive Center at 800-243-0000.
