dell laptop screen is flickering and shooting lines everywhere

Hi guys,
I’m hoping someone can help me as I am pretty much troubleshooting illiterate. I traveled yesterday via air and possibly my laptop took a bump or something because now the screen is loading but within seconds begins to flicker and shoot random vertical and horizontal lines across the screen. It’s also shooting random colors.

I’d just like to have an idea for what is wrong before I bring it to a professional. If anyone has an idea of the problem/solution and possible cost of solution I’d REALLY appreciate it.

Thanks
