Xbox 360 Repair? - Microsoft

My Xbox 360 has been down for 3 days now and I want to repair it. If I send it to Microsoft it will take at least 2 weeks to get my xbox repaired.
Is there a guide or a video that teaches you to repair your xbox?

I suspect you have the 3 red light error. It is the most common error on the xbox.
Sending it to Microsoft will take just too much time. Mine was sent to Microsoft and I got it back three weeks later.
