display gone

[AC Question]

My nexus 5's display suddenly went while trying to change sim cards (didn't even open it to make the change). When I checked my phone, i heard notifications but my screen was black, so I could not access anything. So I guess the display is gone or the brightness suddenly got made to zero? How do I sort out this problem and fix the display?

Did you reboot?

I never swap SIM cards unless I'm powered down.
