That's something to make into a warranty issue before the warranty runs out. If you want to delay the warranty call, extend the warranty now.
I tried looking for a solution online, but I could not find any forums with the same problem, and my problem is that sometimes after turning my LG B6 on, it will be making a rather loud buzzing noise that can be heard even through other audio and even after muting the TV. I can fix it momentarily by simply turning the TV off and on again, but the it can appear again randomly after turning the TV on again later.
Could this be a sign of some bigger issue? I bought this TV refurbished but I would still prefer not to have to return it because it's just too much hassle. Could this be fixed myself, or just ignored?
Thanks for the help
