My advice would be to read the thread you chose to post in. Your answer is within this thread.
I'm having the exact same problem! It's maddening. Do you have and advice? Everthing was fine until I "upgraded" to th X1 box.
Press EXIT EXIT EXIT 1080 on your remote. You should be fine.
I have to restart my X1 box everyday to stop the black flashing. My question is why?
Ping? Explain. And which X1 box do you have?
I know I'm late to the party but I just upgraded and have the same issue. Comcast seems clueless even after sending someone out. My question after reading this thread is - are you changing this setting (1080i) on your tv or through your dvr box? If you are doing it through the dvr box where do I find the menu?
It's in the DVR Settings (gear icon).
Set your X1 box to 1080i reslution vs 1080p. Also, make sure your Sharp TV has the latest firmware updates.
Just connected the X1 to my sharp and I have the same problem. Had tech out 1 time and on ph 4 times with Comcast and no one can yell me how to fix the problem
I have a Sharp TV and have exactly the same issue as well. The screen goes black on the TV. The sound also gets interrupted some of the time, not all of the time, so that part is slightly different with the issue I have.
My blackouts disappeared after I reseated both ends of my HDMI cable.
