Suddenly TV won't detect my Xbox One

This is SO ridiculous. Never had any real issues with my Xbox one, but now that I have installed RDR2, all I'm having are problems. I've been playing, finally, for the past few days, just fine. Today, I go to turn my Xbox one on and for some reason, my
Samsung TV is not detecting the HDMI - I've tried different inputs, switching cords, hard reset, I just tried holding the eject button and the on button at the same time to change the resolution (one I've heard to try) and that won't even beep at me as it
said it would when holding.

At one point somehow I got it to detect, had the black screen for about 5 minutes and then it went to that screen that says "something is wrong" and gives me the option of restarting the box (which it's done this before and I've restarted the box and it worked)
or troubleshooting - however, I cannot toggle to troubleshooting, so I opt for restarting; once I did, the TV is not detecting again.

I just want to play my game - finally a day off, and all I want to do is play. Can ANYONE PLEASE help me?? This is so frustrating. I have NEVER had one issue with my PS4 or Pro, and it seems I'm just having all kinds of issues with Xbox, even when I first
got it - which was only about 9 months ago,

Please, someone help??

UPDATE: Suddenly, TV is showing connection to HDMI on Xbox, however, the screen that says something is wrong, is showing up again, and I click the restart this Xbox, and I hear something happening to the box for a few seconds, and then nothing - it won't shut
off, it won't do anything.

Again - can ANYONE please help me? Sorry, I posted in several areas because I'm new the community support and have no idea if I'm doing it correctly. Thank you!

Pb with Xbox one installation.

The xbox one is on right? The tv won't detect it if it's off

 

Lg 42LW6500 will not detect xbox one.

My friend & I tried to set up xbox one & LG LW6500 TV will not detect xbox one. At one point we connected the controller to the xbox & for a moment it detected then lost signal, it only detected for brief moment. The controller doesn't have any batteries.
It won't detect at all.

Any help will be much appreciated.

Thanks

 

Hello!

Have you tried using the console on another TV? It also sounds like your console could probably benefit from a Soft Factory Reset ("Keep my Games and Apps") to help any corruption or problems within the operating system. Take a look at this support article:

How to reset your console to factory defaults on Xbox One. Also whenever you do get prompted to go to the Troubleshoot screen you can use the D-pad to select the option. You can also do the "Keep my Games and Apps" option from the Troubleshoot screen.
Hope this helps
