Screen error on MacBook?

Unfortunately, my sister just stepped on my laptop. Why this screen error was probably created. Therefore my question is: Is the screen broken or is it perhaps only the cable between mainboard and screen out. If the cable is out, then you can judge it yourself or should you let it do it. And how much would a screen repair cost? (MacBook Air) thanks in advance 😊

Display defect without a chance… Only by exchange reparabel

Today's screens have no more cables to individual pixels, the entire monitor has its own board so no cable can simply fall out and if it were so, then the screen would be black. Since only the exchange of the whole screen helps and hope that there's not broken even more.

Display damaged!

Buy new.

Price unknown because you do not write the model.

Display maybe 400 euro plus pay

That's why you do not just leave such an "expensive" device somewhere.
