Screen went bad -- repair myself or get a new laptop?

I have a Maingear Element laptop that I bought from Microcenter in 2021. Working fine except the screen went dark, so I have to use it with an external monitor. I don't trust MC with repairs plus I am paranoid about giving others access to my data. How hard and expensive is it to do a DIY replacement of the screen if I've never done it before? Or should I just get a new laptop? TIA
