Why won't my console sync button work?

So i have been having this issue, also.

I tried everything that everyone else has suggested, but it wouldn't fix the problem.

But I realized that I always have my chat mixer hooked up to my controller that has been synced to my system for weeks now. I unplugged the chat mixer and it automatically connected to my console lol maybe try that if your using a 3rd party headset.

Lemme know if that helps

You guys can skip all the steps here, because all you want to do is Hard Reset.

1. Wake up your xbox by pressing the power button on the console (xbox logo)

2. Hold the power button on the console (xbox logo) for 10 seconds, or until the console makes an audible and visible shutoff.

3. Turn the xbox one back on.

Done. No messing with power cables, no fiddling with the actual controller itself. All you need to do is follow these steps in order to Hard Reset the console.

Sometimes having a USB cable connected causes this try disconnecting it then

Alright, if doing a hard reset, pulling the sync button back a lil bit doesn’t work then I have a solution ( it worked for me) lets begin.

1. open your xbox shell ( Follow this: https://youtu.be/bF1V1QiB17c tutorial up to 5:35
2. Reseat the ribbon cable (remove it then reinstall it — i found this video extremely useful https://youtu.be/ghcWusCrh30.
3. close your xbox shell
4. Just a tip - before closing your xbox shell test that the power button, eject disk and sync are working. https://youtu.be/bF1V1QiB17c Follow this guy from around 40:00 onwards ( he also reinstalls the ribbon cable here I just thought if the other video was not proving useful you can try his ‘method’ or style.

HEY EVERYBODY,UNSOLVABLE PROBLEM???

So ill get right to it. My last controller broke(semi, dog ate the RB button up). So I bought a new one today and I found that my sync button (ON THE XBOX) does not work. I try pressing it, no blinking at all. I have tried with an USB, nothing happens. I have tried both hard and soft restart, I have tried wiping it (without games) as well. Basically everything you can do. The controller I have ( the damaged one) DOES work with it. It is actually functioning. But It just won't accept a new controller into the system. Is there a way to pass around this? Please help me <3 !!!!

Did you get it fixed?

Could be ribbon cable, RF board or WiFi board.

If holding the power button for 10 seconds to shut it down and clear the cache doesn't work it's probably a hardware issue.

Have you unplugged it for 30 seconds?

Also can you connect to WiFi?

Sorry I hadn't been following this post more closely. Many times the WiFi/Bluetooth board stops working. WiFi modules are pretty cheap on Amazon and eBay. They are very easy to replace. Can't sync if the xbox can't see the controller.

Are you sure your not pressing disk eject button? When pressing the disk eject button with no disk in the console makes a ding sound. The controller sync button is located below the power button.

Also if you have took the cover off the left side and removed the black peace from behind it try doing it agian blow in the console and put it back it worked for me and it is very simple just look up how to open up Xbox And the first 20 second of The video should show u no tools required or very much skill a 8 year old could do it and I tried all of these but none worked until this

Just unplug the Xbox cord and plug it back in with the controller connected to the Xbox with a Android cord

I tried all of these and nothing worked:

1) charge batteries

2) hard reset

3) cable attached

4) holding the controller cack handed - the lot

I then removed ALL cables from the console apart form power and did another hard reset - hey presto, the controllers all synchronised first time!

Maybe this is the last resort before you bite the bullet and send it in for repair!!!

Hopefully this helps someone who gets stuck and nothing else works!

I feel like an idiot! I forgot to attach a cable to the underside of the lid before closing the box.!

I fixed it but yes the button clicks but i wouldent flash but like i said i fixed it

Make sure every cord is unplugged from the USB ports. I tried everything on these lists and finally saw where someone had a slightly frayed wire in plugged in, and after unplugging it he could sync again. Just worked for me too.

None of the above solutions worked for me. Connect a usb wire into the side port of the xbox. (The one next to the button that you push to connect controllers) That controller has to stay in at all times and the button works properly

Key for me was to take the console casing apart to expose inside the front panel. Carefully unclipped the ribbon cable than links the sync button and eject button from it’s housing, gave the cable housing a quick dust (could see a strand of dust in it) and re-insert the ribbon cable (fidgety and be careful) and it cured the syncing problem instantly. I did not apply any contact cleaner spray, just a dust with a soft artists paintbrush.

So for me it was a simple ribbon cable dirty or imperfect connection issue. Console is 4 years old.

Result!

So non of these suggestions worked for me. Decided to open her up and take a peek. Didn't see anything wrong. The sync button would make noise but wouldn't blink. My remotes were stuck in a infinite slow blinking stage. Never connecting. Got tired of wired remote use when I opened it open disconnected Power-sync-eject ribbon. Looked fine. Everything looked fine. Still didn't work. Then I disconnected reconnected black skinny cable going from wifi card on top of metal casing on back left corner. Finally got my remote to connect ?. Nothing else worked but this. Hopefully this helps anybody. Last entry I seen was 2018 on this page and couldn't find anything else online other than hard resets, and part replacements. I guess I got lucky.

For me I had a power bank plugged via USB in so I turned off my Xbox by the plug switch so there’s absolute no power, I took out the power bank then I could sync my Xbox!
I didn’t know power banks could prevent the Bluetooth button from having an affect but to be honest I’m pretty sure it was making the power bank blink like it was trying to connect to something Bluetooth lol anyways hope this helps!

Pushing Sync and Eject on xbox made it finally blink and connect to my controller.
