This happens without a switcher. My contour streamer is connected directly to my Samsung TV using an hdmi cable, and I can not watch the news or a movie without intermittent black screens, video with no sound, sound with no video, and sometimes an error message that the channel is unavailable. We have had cox at this address since 2012, and upgraded to fiber when they did the work in our neighborhood in 2017 or so. We've had the streamer since last year, but haven't experienced this problem until this week. But it has been every day this week.
I understand and I want to help. Please email us the physical address and any other pertinent information to Cox.Help@cox.com with your name and a copy of this forum message. We're glad to assist you there.
