A:Answer My new rear speakers wouldn't pair either and just flashed green on and off. I had the receiver placed on the lower shelf of a sofa table behind my sofa. So, I disconnected the speakers from the receiver and moved the receiver closer to the soundbar, maybe 8 feet away, and plugged it in. It paired immediately. Next, I unplugged the receiver and moved it back into place behind the sofa. I plugged it back in and Waa-Laa it remained paired. Hooked the speakers back up and they worked just fine. I must say the so-called instructions in the Simple Manual that came with the SPK8 are totally useless. I discovered that the detailed manual for my SL6Y soundbar which is only available online contained better instructions for hooking up the rear speakers. Sounds like a lot of people are having trouble pairing the rear speakers. Reading the reviews and questions, there are a lot of unnecessary returns because of the very poor and unhelpful instructions that come with the rear speakers and an equally useless and unhelpful Simple Manual that comes with the soundbar. LG would be wise to improve their documentation.
