I have a Dell XPS 9350, service tag . Suddenly while traveling on a long international flight, the screen went dark. I just couldnt figure it out. Further it went into a boot loop with start up repair. I thouught that the windows was corrupted. Using the Dell repair media also didnt work and it refused to do a Windows reinstall. Said that proper disk volume not found. In desperation I formatted the C drive and then installed windows in Legacy mode with a starndard Windows 10 USB stick. Sadly to state that after full installation and loading drivers, the original problem of screen going dark reappeared. It does however boot into safe mode.
I did the following:
I updated the bios. Then I did a fresh install of windows and it looked good for awhile. I installed the network driver and connected to the internet. I created a restore point as well. I watched again for some time. Then it somehow itself found a device, made that sound that windows makes when a device is detected, and bam, the display went blank. I did the video screen test of Power +D and all colors flashed normally. I went into safe mode and restored windows back to the previous restore point and display worked for some time and then bam again, device detected and screen goes blank. I connect to an external monitor and it works fine. I am writing on that monitor now. I have updated all drivers from the Dell site after having my machine being auto detected and that doesn't help either. I opened up the back, disconnected battery and held power button down for sometime, still doesn't help. What now? I love this laptop and want it badly to get going again.
 
Maybe something with the screen is faulty, check the ribbon cable between motherboard and display.

Would get it to the Dell repair service.
