I turned my 360 on about 20 mins ago, and all the quads lit up red apart from the upper right one. I turned my 360 off and then back on, and all is running normally again. However this is not first time it's done this, it did it on launch day as well, the first time I set it up. I turned it off on launch day and checked everything was in securely and put it back on. What do the 3 red lights of death mean?
