My LG NB3520A Sound Bar not working. I saw a spark come out of the bar. I purchased another sound bar without the subwoofer, but it will not connect

SOURCE: no sound in sound bar and subwoofer

for Jameslicon re wireless sub going on and off repeatedly. Both the soundbar and the sub have 4 wireless channels - try a different pairing of those channels. There is a sliding switch on the back of both units. I set each of mine to channel 4 and the problem went away. There is also a signal level switch with 3 levels on the back of the soundbar. If the wireless channel idea does not work, try a different setting on the level switch. Good luck.
