I got a new cable box now my tv screen keeps going black

My new cable box is causing my TV to have a black screen constantly. And I refuse to change from 1080 to 720 as been suggested in the past

It took me forever to post this because I couldn’t open the last 2 questions. When I went back and forth, I lost my original complaint. Comcast you need to fix this issue, it is so frustrating to even post here.

@user_i1q46b Have you attempted using a different HDMI cable/port on the TV? Is it just the cable box causing the black screen or are other devices experiencing it as well?
