I have a x360 elite, a working xbox live account and until yesterday I could connect to a live section. Today, I can not. I have checked all the connections and they are all good. It seems that the unit, reads my live profile, but I can not connect to live. Again, I check all the connections and try to re-set with no luck. I did notice that when I ask the system to do a connection test the screen goes black. When the screen comes back up it reads "available networks". I know is not the account because I can get acces on my pc. I know all connections are working because I have tested them. Can I get some help anyone?
