To get to the point here. The console will sit at E74 until the GPU gets to about 40C then will restart into normal mode with no problem. A game can be played for hours...until you shut down the console and let it cool.
At that point, it will one of three things:
- Power up fine but will have graphical anomalies.
- Immediately display the boot logo, then freeze with artifacts on screen.
- Dump directly to E74.
Could this just be because the board itself is slightly warped in one area? Or is it that the HANA is failing?
I failed to mention that the system will do this on all resolution settings. I have tried 4 different TV sets, as well as three different monitors. All with different cables. (2 Sets VGA, 2 sets Composite, 2 sets HDMI, 2 sets component) to the same effect.
