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.
Hi, there. I'm so sorry for the issues with your service and I want to help. If the box you 're using is wirelessly connected to the panoramic router, it may be signal interference. You can reposition the router and/or the streaming box to see if it improves for you.
The DVR is on the shelf, a foot above the router. As I said below, I had to change out each of the 3 DVR's I have, one at a time till the picture stopped flipping on and off intermittently, and the problem with the splitter stopped. The other 2 DVR's are functioning on the other 2 televisions, without the picture flipping on and off intermittently. Either signal quality or equipment quality issues.
Last year with the old Countour DVR, I was having intermittent drop outs in the audio. Since this was a Contour DVR, I would "rewind" to see if the audio was recorded, and it was not recorded. Talking with Cox support, they said that I should sign up for Cox Complete Care to keep the service costs low, and that within about 3 months that they should have the problem resolved. I started recording shows, and I was also able to show each of the 3 Cox technicians over 3 months of visits, what was happening. Cox was not able to solve the problem, and they would not refund my money. I had a discussion with a Cox representative about me being able to talk with a senior technician from Cox, with regards to a solution. A senior technician from Cox called me, and he said that he would get further testing performed on the system, and get back to me. About 2 weeks later, he called me to report that there was a problem found with an optical node (see Hybrid fiber-coaxial in wikipedia for details). I was told that a work order to fix the optical node was done, and in about 2 to 3 weeks later the problem finally was gone.
I appreciate that the Cox technicians try their best to fix things, using their training and equipment, but this issue was above their heads, so to speak. I believe that Cox needs to do a better job at monitoring equipment, that affect signal quality. It can greatly improve service, and reduce the number of visits to our homes.
