I have a MacBook Air model A1932 that I dropped, and the display is no longer showing properly. The glass isn’t broken, is it possible to repair it without buying a whole new screen?
If we can’t test the system using an external display (your TV’s HDMI ports are broken) then we will just need to trust faith here. Here’s the part you need: MacBook Air 13" (Late 2018-Early 2020) Display Assembly, Apple P/N 661-09735 Sadly we don’t have a guide to put it in, all we have is the MacBook Air 13" Retina 2018 Teardown I think you’ll find this is too complex a project for a first timer. I really think you’ll need to find someone to help you locally or just ship it off to Apple for repairs.
