My Lg Sn8yg Subwoofer Does Not Function At All But Has Shrieking Noises.

My LG SN8YG was bought 1/9/21 and I have not used it for quite a long time but I found yesterday it does not function at all but generates some shrieking noises. I pull off the power cord and left for overnight but the problem is the same.

Why has my LG sound bar stopped working?

When an LG soundbar stops working, it is often associated with a power problem. Reestablishing the power by either turning on the breaker, checking the power cord, or fixing any of the cables will get the soundbar up and working again.
