MacBook Air takes an impact

[PantherCap]

My 2013 MacBook Air fell from a table onto hardwood flooring and took quite the impact. Upon boot up, I still hear a chime and backlight of screen comes on, but it ends on a light grey screen with black vertical lines, one of which I can track back and forth along the screen.
I understand the logic board may need replacing, however I have read that reconnecting a loose connection may be a saving grace. Could someone please advise. Thank you

Thanks for taking the time to respond!
I tried plugging it in to an external display and it didn’t work. I have pentalope tools, and am confident I could install a replacement logic board. Any suggestions on where to source an inexpensive second hand option? eBay?
Thanks again!
