Thank you so much for your help. I did as you instructed and that solved the problem. I am wondering if an update somehow changed the output of the HDMI port to 1080p from 720p that the technician set the box on when he installed the x1 box. Apparently, a new box comes with the HDMI port set at 1080p (which makes sense), but that was incompatible with my old TV and did not allow the DVI connector to work, as well as some functions under the device settings.
Everything is working now. Thanks again.

I have an old HDTV that does not have an HDMI port. It does have a DVI port. I have been connecting to the Xfinity X1 cable box by using the HDMI out port and going through the adapter to connect to the DVI port on my HDTV. to get the audio I connected to the componet audio on the X1 box. this has worked for more than 3 years with a great picture and no problems.
then about 2 weeks ago, the something happened. The picture was still great, but about every 10 seconf the screen flashes white for a second and the picture returns. The remote has sporadic communication.
Of course, spent a lot of time with tech help to no avail. they suggested I exchange cable box. I did
but no change. I now have my TV connnected using componet cables ( the only option if you don't have HDMI). Everything works except you cannot select display resolution through the help, Device settings, just get a blank screen.
so my quesion is does Comcast no longer support the use of an HDMI to DVI adapter?
