Microsoft has confirmed that from today it will not undertake repairs to original Xbox consoles unless they're under warranty.
The new policy, which can be read in full on Xbox.com, states that its technical support helpline will still be available and a troubleshooting guide can still be found on the official site.
The policy states:
On March 2, 2009, technical support documents and content will be available online. Our Web sites will host a wealth of previous and new how-to, troubleshooting, and configuration content that has been revised and updated to meet our customer needs and current support model.
If you have an Original Xbox console that is in Warranty that requires a repair, you will be able to submit an exchange request for an upgrade to an Xbox 360 gaming console online.
