Dark/very dim screen Acer Spin 3 SP315-51

Hi,

I've had the Acer spin 3 SP315-51 for a day and then the following day the screen isnt coming on but the laptop was on. I connected it to my TV and it showed the that it was working but nothing on the laptop display. I later noticed, by shining the lamp on it, the screen on the laptop was on but very very faint. I updated my BIOS and still nothing.

What can i do?
