Have to unplug and replug HDMI cable or TV image to show up

Neither solution here worked for me. I went out and bought the fastest HDMI cables. They support 60/120/240/480 and 600 refresh rates. Also says High Speed 10.2Gbps+ I also unplugged my xbox one and replugged it back in. When I go to the troubleshooting
it says "Looking for your tv picture..." After about 5 seconds it says it found a signal and says it will take up to 6 to 12 seconds for the tv picture to show up. However, in about 5 seconds it goes back to looking for a signal. It's really intermittent.
I wonder if this is a problem with my cable receiver. It's a motorola from comcast xfinity. All I have is HDMI cable from cable box to xbox one in and then HDMI cable from Xbox One out to tv HDMI1 slot. Really simple setup.

I had this issue too. For me the HDMI cable was loose on the XBoxOne side. It worked after unplugging an replugging the cable.

Hi,

I experienced the same issue. What I did to resolve it was :

I unplug the HDMI cable and rebotted my cable box. I replugged the HDMI cable and it worked perfectly !

Hi there. I'm sorry that you're having trouble with your Xbox display connection to your TV.

Have you tried unplugging and replugging all the cables on your Xbox/TV? If not, that is a good first step that sometimes relieves the issue. Unplug the HDMI cable from both the Xbox and the TV, then unplug power and all peripherals (Kinect, controllers,
keyboard, etc.) from the Xbox. It may help to do the same for the TV. After waiting a few seconds, plug everything back in and fire up the Xbox again. If the problem is gone, it may mean that a cable connection was loose or a cable is faulty. If the problem
still persists, try plugging the Xbox HDMI cable into a different HDMI port on your TV and check for the problem again. If the problem goes away, it may mean the original HDMI port on your TV is faulty.

If the problem still persists, try using a different video connection from your Xbox to your TV, such as the Xbox component or composite video cable (red/green/blue or yellow RCA cables). If you still see the lines, it may mean that the graphics card on
your Xbox is faulty and it needs to be repaired. Otherwise, the issue may be with the HDMI cable.

Let me know what happens, and hopefully we'll get you back up and gaming soon!

I've been having this issue for awhile now. Only fix I have found was unplugging the Xbox and then unplugging the HDMI cable then replugging HDMI then power. Only works for one shot then I have to redo it if I play a game.
