My Xbox series s when I turns on it stays in the Xbox logo then flashes then shuts off

Hi Dominic, I hope you're doing well. I am an Independent advisor, and I am here to help you.

Let's perform troubleshooting steps on your console, but please let me know if you have already performed the steps so we can proceed to the next steps needed.

If an external hard drive is plugged into your console, please unplug it so we can determine what is causing this issue. Please do not plug in your external hard drive while we perform troubleshooting steps.

Please follow the steps to Power Cycle your Console:

​​​

1. Turn off your console by holding the Xbox button on the front of the console for approximately 10 seconds. The console will turn off. ​​​

2. Turn your console back on by pressing the Xbox button on the console or the Xbox button on your controller. ​​​

Once you have done this, please check if you will encounter the same issue again. If the issue persists, please continue performing troubleshooting steps on your console.

Please follow these steps, but don't worry; you won't lose anything as long as your console is connected to the internet. Please be reminded that resetting your console will remove the accounts currently signed in on your console, but you can add them back, and you will need to set the account as Home Xbox if there are any.

1. Press the Xbox button to open the guide.

2. Select System > Settings > System > Console info.

3. Select Reset console.

4. Reset and Keep my games & apps.

Once done, kindly check if you will encounter the same issue.

Turns out it was somehow trying to connect to either the xbox one s or xbox series s consoles in my house for some reason. Turning them off fixed it.

Sidenote: In all my experiences with wireless xbox controllers (xbox 360, xbox one, xbox series x/s) the sync button needs to be held to be put into pairing mode (quarter ring rotating clockwise /flashing xbox logo), while the button on the console needs a single press, if it helps anyone.

Im having the same issue but when I try turn mine off normally the xbox logo flashes like its trying to donwload something it stays there for like 5 mins then the console resets back to the green screen and then followed by a black screen

So this is what is happening. Turn on by pressing the xbox logo and the xbox light come right up and stay bright. the drive or something else inside the xbox click then turn off then do the same process 2 more times and then the xbox shut down. When i
turn on the controller, it blink to connect but never connect. Hope this hlps. Thank you for looking into it.

i've tried to reset by pressing the sync button, the xbox logo blinked fast, and i turned off and on again, it stay on but the problem is not that iot suddenly turn off, it stay on as long it don't go in sleep mode, at that point when i try to turn it on it will shut down after 1 sec, it stay on just enough to be seen by the computer, to solve i plug the cable for one sec and it work again as intended in wireless mode

now, i just wait for it to go sleep and see if it will turn on again

edit: the reset with sync button seams to have resolved the issue
