Hello GITBIT90!

If you find that these steps are not resolving the issue, you can check to see if your device is still covered by the warranty and follow the steps for a repair.

First, sign in at Device Support and then select Register new device. After you've registered, you’ll see the warranty status for your device. If it’s within
warranty, repairs are free. If your device is out of warranty, you’ll be charged a repair fee.

Submit a service order request

After you’ve registered your devices, follow these steps:

1. Sign in to the Device repair page with your Microsoft account credentials.
2. In the Overview section of the Device repair page, select Repair my device.
3. Follow the onscreen steps to complete your service order request.

After Device repair receives your submission, they’ll send you a service order number and an order confirmation email that has shipping or drop-off instructions.

Send in your device as soon as possible. If you don’t ship within 30 days, your service order is canceled and the shipping label will no longer be valid. In countries or regions that offer a drop-off exchange, you must go to the drop-off center within 7
days from the date you created the order.

If after 24 hours you haven't received a confirmation email, check your email program's junk folder or spam filter. If you don't find the email in junk or spam, contact Xbox Support.

If you receive a message that your phone number or email address is invalid, go to How to change the email address
associated with your Microsoft account to update your Microsoft account information.
