I think my X-Box 360 is broken.

Whenever I turn on my 360, a red circle appears where it shows the amount of controllers attached. I am very confused about this and I do not know what to do about it? I cannot play any of my games and I cannot even access the X-Box 360 menu screens.

If it's 4 lights you may wanna check whether the power cord its plugged in properly. 2 it's lights it's over heating, one light check the AV cable, if it's 3 lights it's toast.Ilikemyname420
