I am thinking that you have 3 red lights showing on your xbox, if that is the case don't mess with it as it will just make it worse.

Leave it call Microsoft, you should still be covered, and they will request for you to sent it to them and they fill either fix it or give you a new one. This is becasue it is not your fault that the red lights come on, it is due to the actual xbox going wrong.

Hope that helped
