I have an Insingnia Roku TV that is about 2 years old. (NS-39DR510NA17). It recently started dropping the picture while watching anntenna TV. The picture and sound go away, but quickly return (maybe in a second or two). This happen about twice in a minute. Happens on all channels, pretty much all the time.
Tried adjusting, and even swapping the antenna with another. Still happens. Tried two other TVs in the same location and neither has this issue, so I'm sure it is the Insignia TV.
Is there a hard reset or software update that will fix this?
