so, i finally got around to buying an Xbox 360. i got what i thought was a good deal on eBay for a used Xbox supposedly in perfect working order. it comes in, i hook it up and everything seems fine. i was going through the menus, deleting the former owner's files and such, and when i get ready to insert a game, the video messes up and the Xbox locks up. i turn it off and back on, only to get the infamous 3RROD. after messing with it a while, it came on one time, only to mess up again in the same way. since then, i can't get any video at all; only those 3 damn flashing red LEDs. to make matters worse, i noticed that the warranty sticker is broken, so sending the box to Microsoft is probably not an option. i'm trying to work with the seller on it, but if that doesn't go well, i want to know what are my options? i've seen a few things about fixing 3RROD, but they all seem to have something to do with a specific error, and i'm getting no video at all. anyway, free grog to all who can help.
