Microsoft has been having a rough time with their kiosks in various stores and locations. Wal-Mart shutting them down because they interfere with wireless devices, and now a “black screen of death” as it is being called on some of the consoles.
Xbox-Scene has the image, and the details.
So I went to the local Wal-Mart and walk on the 360 display and was like well I’ll see If I can get a better look at this deal since few people were in the place. I turned the corner and found the Contact Xbox support screen. The xbox was blinking red and claiming error 74.
