When pairing be sure the bar and sub are very close to each other. If pairing fails when they are less than one third meters apart then it has failed.
My name is Wojtek, I live in Poland. I have got a LG Soundbar LAS450H. Soundbar is 2,5 year old.
Unfortunately today i have noticed that subwoofer lost connection with main unit. Led light on it is red.
I have read that I need to pair it manually but my soundbar is not entering the WL RESET mode. I put volume to minimum and hold for more than 3 seconds mute button but nothing happens.
I have tried to reset main unit holding "-" button on main unit and SOUND EFFECT button and it is ok but it is not solving the problem.
After few times green led on subwoofer blinks very fast 3 times per second but it still does not connect with main unit.
I have check the software version using music flow bluetooth android apk and it is actual version.
I have to do something before i will send it to service. Main problem is that my stuff is on the wall in living room and there is a lot of work to do to put it off.
I am sorry for my language but i think that you can understand what i want to tell You.
