hello! It turns on normally, but when the user/password window exits there is no longer any video on the macbook screen, there is sound, I have a backlight because it turns on and you can see the apple. So when I connect the external monitor I have video on both screens and when I disconnect it it disappears

Check open lid sensor voltage to ground.

Test in safe mode boot.
