Dont worry, even if it was under warranty sony would not have replaced it, ive gone through numerous broken ps3s and each time sony has refused to honor their own warranty so ive been forced to fork out for a new one!
Not to mention a Sony/Ericsson phone that broke after 2weeks, sony`s response "Yes sir thats covered by our warranty, that`ll be
£80 for shipping and paperwork please."
Sony warranties aren`t worth the paper theyre printed on
