I have tried the sound bar configuration, in fact I usually have the sound bar hooked up. Here’s the scenario: I only
find it happens with NBC and it only happens with live shots ( from the network). Examples would be the lead in to live programming, TodayShow, Nightly News. It happens every time those shows come back on from commercial break as well as well. This tv is less than two years old. Enough to make me want put it in trash!
