Question ASUS X550CC - The laptop no longer displays anything

[Fusher]

Hey, hello! I have an Asus X550CC laptop and two days ago it fell from a distance of about 40 cm on the hard surface. The laptop fell on the front (back), not on the display or anything else. After the fall, it worked for 30 minutes without a problem, but after suddenly it was blocked, it simply froze and no order was placed on it but the image remained (the windows blocked being more explicit, the image remained) . Now, when I turn it on, there's nothing on it, absolutely nothing, but once I press the power button, it shows how the diaplay starts, that is, it just lights that nothing appears on the screen. I made it out to see if it's the HDD, but it is not. Then I looked at the display, it's okay too. I tried with an external monitor but still does not see it. I think the motherboard broke down, but the HDD's LED lights up and shows how it works, the caps lock or num lock lights also work. Anything else, what? If you think you may be in the circumstances in which it starts, the display lights up but nothing appears on the screen.
How can I figure out the exact problem?
Thank you! ☺☺

The hard drive is likely damaged internally.

I pulled the hard drive out of my laptop and started it without it. Nothing changed.
