Solving black screen on a Macbook Pro 13''

Hi,

I've a macbook pro bought in 2016 (Macbook Pro Retina with Touchbar) which is experiencing a black screen. I just rebooted it today and it did not restart with a working screen. I can use an external screen and apparently it works perfectly, but the built-in screen keeps black.

I reset the SMC and PRAM, but it did not solve. I cannot even see the apple logo whilst loading.

Is there anything else I can try by my own?

thanks
