If your Xfinity Flex or X1 is displaying a black screen, then there's some possibility that your Xfinity Flex or TV is having some fault in cable connections. Earlier, there were cases where users encountered black screen issues due to the frayed, damaged or torn wire. So, try to check all your cables that are connected to your Xfinity Flex or X1 and TV.

If you've found any torn, damaged or frayed cable, we suggest you replace that cable with the new one and connect it securely to your devices. After this, turn on your devices and check if this resolves the black screen issue.

Also, ensure that all the cable connections are tightly connected to your devices. Check all the cables separately.

If that didn't resolve the issue, check this detailed guide on How you can fix Xfinity Flex Black Screen.

Borrowed a friends HDMI cable and no difference. Unplugged the cable as suggested by Krazy2768 it did not give any message about the HDCP. Went in to Netflix and started it anyway and after the screen went black I unplugged the HDMI cable and then when I
plugged it in got a message about secure HDCP connection established and worked fine. But after reboot of xbox black screen again.

Very sorry to hear that, CottonCandyCrue! As a preliminary step can you double check that the HDMI cable is hooked up correctly and not loose? If it is that may be why you're encountering the black screen. If you still see a black screen after checking the
connections you may have a faulty cable. Let me know if this sounds like it might be the case!

I have triple checked all cables tried three separate hdmi cables as well. Power cable is fine white light when Xbox is on orange when it's off. After about five minutes of pure black screen my kinect appears to power on but nothing on screen. I guess it
is bricked.
