I'm having a problem with my XBox 360 at home and figured I'd give this site a shot to try and obtain more information on it. This is my second XBox 360. My first one was a refurb. unit that eventually crapped out again with the RROD. The latest unit was purchased brand new on 4/6/2009. I hardly play the thing but decided the other day to finally open Madden 2011 that I received for Christmas. It needed to run an update so I let it run the update. The game played fine the entire night and then when I tried to boot it up the next day, I now have a lower right quadrant red light (quadrant 4) and an E71 error code. Does anyone have more information on this error and/or possible fix? Thanks.
