Our LG SPN5B-W wireless subwoofer stopped syncing with the SN7Y soundbar (just had a green blinking light) - no matter what i tried, from resetting, updating or looking for WiFi router interference it would never sync. After a little research I purchased this spare part and now I have a working sub. The part was easy to order, was deliverd in a few days and came well packaged. Fitting was really easy as well. Great service. Thank you.
