The thing is also that Redherring managed to resolder the gpu successfully on a Nintendo Vegas, but it still didn't boot. There must be another thing we're missing (atleast on the Vegas, The Lightiing may not have such a problem).When assembling my board redesign, both chips would get hot but no display. I measured the current each voltage line was drawing and found improper values. I would check that as well as shorts between all the voltage lines since I have discovered the GPU internally cracks under the heat required to remove the GPU from the original board in the first place, therefore shorts out some if not all voltage lines internally. This is why nobody has been successful with a Wii board redesign. The RAM and CPU can take the heat, only the GPU suffers from this problem.
