DVD Drive Replacement through Xbox Support
Open your Internet browser and navigate to the Xbox service website.
Click the green "Request a Repair" button. Input your Xbox email address and password. Register your Xbox 360 console's serial number, if necessary.
Click the drop down menu "Problem Type." Choose the most relevant issue. If you believe the hardware error is as a result of the Samsung DVD drive, you should select "The disc is unreadable or undetectable."
Print the shipping label issued by Xbox. Pack your Xbox 360 in a shipping box and apply the shipping label. Take your package to a UPS shipping location for transport. A repaired or replaced Xbox 360 will be shipped to you.
