My MacBook Pro M1 Pro from 2021 suddenly stopped working. The built-in screen is not showing any image, I can see because of the backlight that the screen is working but I cannot see the image, is showing blank.

However when I connect an external display everything seems to be working (Except by the built-in screen).

Do you have any suggestions?

I already tried reinstalling the Mac OS Sonoma from recovery options. I am planning reset and delete all the settings. To see if that works.

Another thing is that when turning on I can see the Apple Logo but it's very blurry. You can refer to the images attached ( that is from the recovery screen).
