I got the 3 red blinking lights (upper right does not blink) on my xbox 360 out of the blue one day. I found the troubleshooting guide on xbox.com and it just said to unplug everything and retry. I did that, even tried moving to another part of the house cuz i thought maybe it could be a power thing with the outlet. no luck.
warranty you ask? nope, that would make too much sense. i done had to buy it used on craigslist cuz i’m a cheapskate, i’m paying the price now – doh.
if anyone else has had this problem and had success fixing it, i would be very appreciative if you could share your knowledge.
thanks.
