Things You'll Need
Instructions
Remove the main display connection from the Xbox as well as the network cable. Do not disconnect the Xbox 360's power cord. This connection is on the back of the console directly opposite to the power button.
Turn on the Xbox 360 console and wrap the towels around it. Ensure the console is completely covered, preventing any air from infiltrating into it.
Allow approximately 15 minutes for the console to overheat, effectively lowering the GPU solder joints and re-joining them with the motherboard's surface.
Remove the towels from the console and turn it on. As a result, the console should show its regular green lights instead of the red lights previously displayed.
