Our Vizio speakers make noise the entire time the t.v. is on. What can we do to fix this problem?VIZIO VX37L backgroud buzzing noise constatly (audio) increasing as volumne increasing. My knowlege is limited but tried looking at audo conttol setting,(nothing in which I could relate) also I found under advance picture adjustment DNS (noise reduction). it didn't seem to realate to aduio. If audio is fine and new speakers would cure all, I'd be a player.
I have a Vizio 47. It also has buzzing noises. Both speakers. Have cable, but no HD cable box --- no box at all just direct hook up to wall. I have an internet modem with a splitter for the cable but no direct connection to internet and TV. Buzzing noise stays pretty much the same in volume even when you increase the volume. I can't find anything in the audio set up to help out. But seems to definitely be speakers as I turn them off on the audio set up the noise disappears. Of course then all sound turns off.
