Black screen on Xbox one S

I bought my Xbox One S in December 2018 and currently i'm experiencing 2nd black screen in a few months.

I got first black screen in January 2019 and got my xbox fixed by Microsoft. Now in June 2019 i got 2nd black screen. So frustrated!

I'm curious what did they fix? What is causing black screens? I'm also playing my games on external hard drive to not strain the internal hard drive but black screen keeps happening.

I've tried troubleshooting steps (except the usb update cause i don't remember my dashboard version and i still have black screen) so i'm confused nothing works.

I'm thinking if it gets fixed for a 2nd time i'm going to sell my Xbox One S and buy an Xbox One X so maybe i would have better luck with different hardware. I really don't know... my white Xbox 360 Pro is still alive and never got red ring of death and
Xbox One S keeps breaking with black screens. I'm lucky with Xbox 360 but so unlucky with Xbox One S. I'm so disappointed with Microsoft hardware.

My xbox one s is doing the same thing. Shows green xbox title screen, then no dashboard; just a black screen. Was playing it roughly 7 hours ago... WHY

no its not on the S. It's only Xbox One (1st generation 2014 Era) released xboxs that are being reduced to black screens. Microsoft wants us to buy new ones

My Xbox one s only goes to the black screen of death 😭😭😭😭😭😭

Hi

My Xbox one S cannot play all my UHD now. Once I inserted the disc, the screen stayed in black all the time. When I pressed button to exit the disc, the screen still remained black without going back to the main menu of Xbox. 1080P discs worked fine.
