Xbox One X : "No Signal Detected" to my monitor after turning on console

Hey there, thanks for reaching us out!

If it is still under warranty, I suggest you send it back to Microsoft for a repair.

Here is how you can do it:

Hi there,

yes you would still be able to send it for repair when it isn't under warranty, but there will be a fee for the repair. The fee itself will be shown when setting up a repair.

I myself don't think you have tried all steps yet, so would try those first.

just to be 100% sure, the HDMI cable on the console is connected to the Out port?

if that is the case then please try these steps again:

please try the manual power cycle steps like mentioned on the following link, be sure to wait at least 60 seconds before powering on again:

http://support.xbox.com/en-us/xbox-one/console/power-cycle-console

if that doesn't work I suggest trying these these steps:

1. Power off your console, and then unplug the power cord to ensure that the console is completely powered off.
   
2. Wait 30 seconds.
3. Plug the power cord back in.
4. Press and hold the BIND button (located on the left side of the console) and the EJECT button (located on the front of the console), and then press the Xbox button on the console. Continue holding the BIND and EJECT buttons for 10-15 seconds. Listen for
   two “power-up” tones a couple of seconds apart. Note If you don't hear two power-up tones after 15 seconds, it means this failed. Likewise, if you hear any “power-down” chirps, that also means this failed. You can release the BIND and EJECT buttons after the
   second power-up tone.
   
   This should show a menu with the option to factory reset the console, if it does not please try the steps again.

If that does show a menu then try the factory, if it doesn't show a menu at all please try the offline update steps here:

If all of these steps fail then a repair is likely required.

This is no longer under warranty sadly. Would I still be able to send it in for a repair despite it not being under warranty?
