Sync button on series x console wont work

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.

You're correct that this is a feature for the Xbox Series X controller. Basically, your secondary device is the PC which you just need to press and hold the sync button for around two seconds.

Yes, to re-sync it to your Xbox simply double-tap the sync button.

Make sure to perform a powercycle on your Xbox if double-tapping didn't work.

Hello MainTarsier447, My name is David. I am an independent advisor, happy to help you today.

I'm sorry you're going through this.
Make sure the HDMI cable is properly connected to both your Xbox Series X and your TV. Try different HDMI ports on your TV and make sure they are working properly.

If the issue persists, you can try resetting the video settings on your Xbox Series X. To do this, press and hold the power button on the console for about 10 seconds until it turns off completely. Then press the power button again to restart the console.

If the controller does not sync automatically, you can try to sync it manually. To do this, press and hold the sync button on the front of the console (next to the USB port) and at the same time press and hold the sync button on the top of the controller. Wait a few seconds and both devices should sync.

Best regards.

I'm sorry you're experiencing this issue with your Xbox Series X controller. Here are some possible solutions you could try:

Restart your Xbox console: Press and hold the power button on your Xbox console until it turns off. Next, disconnect the Xbox Series X from its power source. Turn off the Xbox controller and remove its batteries. Finally, connect and turn on your Xbox Series X.

Restart the controller: Press and hold the power button on the controller for several seconds until it turns off. Then turn it back on.

Pair the controller with the console again: Press and hold the sync button on the console until the power button flashes. Then, press and hold the sync button on the controller until the lights on the controller flash.

Best regards.

Additional info:

Tried using the sync button on the pad (next to the bumper) and the sync button on the console itself (next to the button to turn it on). Pressing the sync button on the pad and console together just caused the lights on the console to spin for a few seconds
before it just goes back to the central light lit up, the pad still wont connect.
