Product Review (submitted on November 29, 2011):
We actually bought two of these tvs on the black friday special at Wal-Mart. We've plugged both in and they both have a ringing/buzzing sound coming from inside the tv. It is there when you mute the tv or if the volume is on. When you turn the power off it makes the sound for about 20-30 seconds and then is gone. I called Vizio customer service and it was great service. They are sending me a replacement tv but I don't want the ringing and I'm wondering if anyone else noticed this problem. Two TVs and both make the ringing sound so it doesn't look good. Nothing hooked up to them either except U-Verse and still makes the noise when U-Verse is not hooked in. If this is a defect with this product then I'll go ahead and select something different. I really don't want to because the picture is awesome so hoping it's just bad luck with the two we got.
