Macbook pro has startup noise but black screen. Keyboard and trackpad of macbook pro not working too.

Hi everyone,

I have a MacBook Pro which makes startup noise but is showing black screen.

The keyboard and trackpad of my macbook pro is not working too.

I tried to create a USB bootable installer and attached an external keyboard to attempt to reinstall it.

However, nothing moves.

Any other things that I can try?

Thank you for assistance.
