Hi everyone, new here and hoping someone can answer my question below.
OK we have the above Vizio and all of the sudden the volume on the TV speakers is at 100% and will not go down. If we turn the TV speakers on you hear a buzz then after about 15 seconds the sound comes on @ 100% even with the volume turned all the way down. We can run the audio through the surround sound just fine, we just can use the TV speakers for the X-Box. We do not want to run the X-Box through the S/S if we do not have to. Is there an easy fix or does it sound like the main board is bad?
