Hello quanwashington,

Thank you for posting on the Xbox forums. We need a little more information to ensure that we provide the correct solution. Are you using an Xbox One or Xbox 360? Are you referring to the Xbox button on the controller or the console? Is the Xbox button
not responding when you press it? Be sure to let us know the results!

My xbox did the same at first wouldn't load home menu so I held xbox button to reset and now it won't boot up. Xbox light on console stays on and light on control turns on and off. My TV says no cable connected. Currently on hold with xbox support. This
sucks.

I have already tried that. When I try to sync it, nothing happens. Is there a certain way to sync it. I had my Xbox on and held both sync buttons. Does my controller have to be on? My controller won't stay on unless I hold the home button.

Putting it in DMZ opened it up. Now I'm just nervous it won't stay there. Is there any real danger to the rest of the devices on my network by putting my Xbox in DMZ?
