|I was going to reply: "No - most (all?) notebook/laptops have a VGA port to which you connect an external monitor?"|
However I discover (useful to check on Dell's site) that you have a mini touch-screen tablet system?
Seems Dell make usb-C adapter to allow assorted connections to external destinations... Some general details here - thought I feel you may not be able to connect to an external display that way...
Have you the manual for your Dell device?
How old is your Dell device?
There are a few led style indicators that ought to flash, glow etc. depending on whether or not the tablet is even starting up; and this presumes the battery is charging of course when the mains adapter is connected....
The user manual lists the assorted blinking lights significances...; perhaps have a look-see?
Incidentally when you say the screen is broken - do you mean it's physically damaged (as in cracked etc.)? What happened immediately prior to the screen failure?
