My Xbox controller flashes using the home button, yet when I use sync it turns off

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I'll recommend you do a power cycle to clear the system cache

- Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.

- Unplug the console's power cable. Wait 2 minutes.

- Plug the console power cable back in. Press the Xbox button on your console to turn it on and check if it's all good.

If that doesn't help, Please see a well detailed guide on how to troubleshoot the Xbox Wireless Controller here https://support.xbox.com/en-US/help/hardware-ne...

If that doesn't help with the issue, you will need to send the device to Microsoft for a service repair/replacement. You can see how to do that here https://support.xbox.com/en-US/help/hardware-ne...

If the controller is still under warranty, the repair/replacement is free. If the warranty has expired, it will cost you a fee depending on the type of controller you own. You can check out Microsoft's out of warranty service cost here https://support.xbox.com/en-US/help/hardware-ne...

Hope this helps!

Yes, I'm trying to connect my controller via Bluetooth on my Windows 10 PC (It worked before yesterday). When I connect my controller via USB Cable it works fine.

The XBox Button flashing slowly when it's turn on. When I press the sync button to connect via Bluetooth, the XBox Button flashes for 1 second and the controller turn off.

My sync button turns off my Xbox one X and won't connect any controllers.

When controllers do connect they disconnect and flash.

Had this problem since beginning of February.

They are all different brands of wireless controllers. Microsoft to Amazon. NONE will connect. Yes the steps are followed perfectly and variants of the steps.

Press the ON X button. Flashes in a circle. Press the Xbox Connect. It too flashes. Press the small controller sync. Flashes slow down. After less than 1 minute the Xbox stops flashing. Then the controller stops flashing.

Only the one controller that came with it used connects. No other will. Even when I unpair, turn off, and reset the xbox. It will see NO controllers except the when I turn on the one it likes. One and that is it.

These other controllers have NO issues with my PC or Xbox 1. Just the 360.

Sync the Controller:
To sync a wireless controller with your Xbox, follow these steps:

Press the Xbox button on the controller to turn it on.
Press and hold the small sync button on the front of the Xbox Series X console (located near the USB port).
While holding the sync button on the console, press and hold the sync button on the controller (located on the top near the Xbox button).
Release both sync buttons when the controller's Xbox button starts flashing. The controller should now be synced with the console.
