I figured out what it was I'm an inexperienced X-Plane user and my failures were activated! Sorry for the assumption that it had something to do with the 737 its a fabulous aircraft!

Yeah, like I mentioned the plane was stable, the engines were running and the stand by instruments were working. I think its just a bug that happened but yeah..

No, I was outside looking at Ortho and when I switched back to the cockpit it was just like In the screenshot. I tested and tried another flight which took over 3h airtime with a different livery and that worked fine. I'm new to X-Plane do liveries have an effect on this?

I was flying a medium hall flight from London to Greece and after around 2:30h all my screens turned black and the autopilot panel also didn't display any information. The weird part was that everything was still working, the AP stayed engaged, aircraft could fly on heading mode etc.. I had engine power, and the APU started normally. What really confused me was that the EFB also turned off. When loading back in cold and dark everything was back to normal. I am really puzzled on why this may be...?
