Black screen no matter what I do.

Hey folks

I own a MacBook Pro Retina 15" from late 2013, it worked just fine untill now.


What happened:

I tried to Install Windows 10 with bootcamp. The first try didn't work, so I did some research and in a German forum a guy said that when you make an ExFat partition yourself,
that error doesn't happen.
It didn't, but after installing the display remains black.
I can hear the boot sound and the fan, but nothing happens.

I can see that the display is active, so it's not broken, just black.

I tried the almost every key combination from recovery-mode to PRAM-reset(in this case it resets, I hear the sound once more).

All I can imagine is that something with the bootloader or the drivers must be wrong.

I even called support, he couldn't help me.

Can anyone help me?
My priority right now is to get my Macbook up and running, Windows 10 doesn't matter.
Thanks

Will external display work? If so, most probably the internal display is not working. You can bring it to apple store for a free checkup.

It does not. Thanks for the answer though.

I brought it authorized repair shop, hope I manage to install Windows 10 afterwards.
