Why does my Xbox one x black screen for a few seconds every 15 minutes or so.

Hi Thomas, my name is Jhon, and will be a pleasure help you

You may experience poor video quality or a black screen when watching TV with Xbox. This may be due to the following:

-There are problems with the HDMI cable
-There are problems with the way the cable box is connected
-There are problems with the decoder configuration

You can find some possible solutions in the following link:

I hope the information I gave you has been useful, have a happy day.

Im having this same issue. I changed hdmi's but every couple of minutes the screen black out for a few seconds then come back on. I plugged the cable box directly into my tv and the screen does not black out. Last time this happened i had to get a new xbox

I'm now experiencing what appears to be the same issue as Terrell Watson. My xbox had started behaving glitchy and slow for the past week or so. Then today at start up my Xbox One was stuck at the green loading screen for 10 plus minutes before the screen
went black. My Xbox One then hung on a blank black screen forever sometimes displaying an icon for a few seconds before going completely black again.

Hello Rahl33,

I have seen the same issue with my Xbox One S. It seemed to happen more when playing Halo 5 ...? I did change out and started using a different HDMI cable. And, it seems to have cleared up (stopped) for now ...? If it starts happening again I may try resetting
my console back to factory defaults.

Good luck and good gaming,

P.S. Your English is fine

Not sure if this is related, but TV started to randomly freeze for me since the last update. Sometimes it will just give a black screen and do nothing. Sometimes if my Dish DVR is on pause and on the screen for 15 or so minutes, it will go black and eventually
kick me to the TV app logo on the home screen. If I go back into it, the screen is still black. sometimes hitting play will load the video after 5 - 10 seconds, i've had to power off and back on again to get working again a few times.
