MacBook Pro dead. Only ESC button showing

I have no idea what to do. This happened months ago. However, there are valuable documents, etc. on my dead MacBook. It seems it’s a problem with the lighting on the screen. Like the display is dead. 

I was wondering if I plugged it in to my tv to mirror screen, would I be able to see the desktop?

I am hoping to get the information off the hard drive. But right now, I cannot even navigate or login into the computer because the screen is dead.

Like I said, the only button being displayed is the ESC button in the top left of the Touch Bar.

Thanks!
