We've had our Insignia NS-65DF710NA21 for about 3 weeks and have started seeing a single horizontal line scroll down the TV every few minutes or so. When the line moves down the screen, above and below the line the picture is offset. So far, we've seen it on live TV on the broadcast channels...during sports, QVC, SNL, etc. but not pre-recorded TV. It happens when the TV is connected to the cox contour box but not the cox mini box. The same boxes connected to other TVs don't cause this problem. We've switched HDMI ports, tried different cables, etc. This doesn't happen on the menu screens, on pre-recorded shows or the news, or on streaming services. Any suggestions?

It has actually gotten worse since my OP. Live action still has the cascading horizontal lines, but now cartoon channels are glitchy and jumpy. It's as if the picture is stuttering.
