I have two children both have the white xbox 360, my sons has the red ring of death, & my daughters will not power on, please help if you can, also some one told me i can trade them out with microsoft for refurbished, i have the boxes, is this true or false? thank you Mark

Im not mark but if you have the box the one with the red ring of death version it should be under warranty as for the one that doesn't power on you can use its serial number to see if its under warranty on xbox home page (and there is a temporary red ring of death fix i used too seeing as Microsoft has know to find out when giving a refurbished one i know it looks stupid but it works look up towel trick in youtube im not sure behind the concept of how it works but i did it 3 different times buying me like 1.5 months before i turned it in it consists of overheating the 360 with towels its understandable if you think it looks to risky)
