I bought an Xbox 360 from ebay and was trying to fix it. When i received it the error code was 0020, after i did the penny fix it gave me error code 0031. I am not sure what else to do. If you have fixed these error codes before please let me know how to fix it! Also i forgot to add that the fans turn on for about 1 second when the system turns on then they stay off. If you have any questions please ask. First fix: www.youtube.com Second fix: www.youtube.com
