Laptop shows strange screen but not on monitor

Does anyone know how to fix this? The problem is from my friend and I couldn't help him, I guess he broke something on the screen while transporting it.

Hmm don't know please help

Years ago I had such a picture on my PC. Once I swapped the graphics card * then it was gone.

*(no guarantee).

Either LCD or graphics card.

Connect an external monitor - if it shows a picture, the LCD display is probably defective.

However, this is a very expensive replacement part.

I can think of the following options:

Display panel defective
Connection cable between mainboard and display defective
Connection cable is loose

Replacing the display panel will be quite expensive, the cable maybe a little less, but it could be difficult to get. If it's just a loose connection (third option), then you just have to plug the cable in better.

In all cases, of course, you have to take the laptop apart

If it is OK on another monitor If the display is broken and the graphics card is OK.
