Instructions
Open the "Xbox Online Service Center" Web page in your Internet browser (see Resources).
Click "Start a repair request." If you have not already registered your Xbox console, you will need to do so to be eligible for the repair service. Click "Register Now" when prompted and follow the steps.
Fill out the repair request form. You can find the "Error Code" by turning on your faulty Xbox console and making a note of the number displayed on the error screen.
Click "Submit" to complete the repair request. Microsoft will send you an email to confirm your order and send you a box in the mail to return your console.
Place the faulty Xbox console in the box and seal. Do not include any Xbox accessories in the parcel unless otherwise instructed.
Send the parcel back to the Microsoft Repair Center using the supplied address. Your repaired console will be returned within six weeks.
