Things You'll Need
Instructions
Turn on the Xbox 360 console. Make sure that three of the four lights are on. If it is anything other than three lights then this fix will not apply to your console.
Detach all cords from the Xbox 360 console aside from the thick gray power cord. Warm up the console by turning it on and allowing it to sit for about five minutes.
Cover the Xbox 360 console using three large towels while the system is still powered on. Use each towel to completely cover the console by wrapping it one at a time. Make sure the console is wrapped completely so no air can travel in or out of the towels. Allow the covered console to sit, remaining wrapped inside the towels for 20 minutes.
Remove the towels from the system and reattach all necessary cords back onto the rear of the Xbox 360 console. Press and hold the green "Power" button until the green light turns off and press it again to reset the system.
