When I got the phone there were multiple problems which I can’t recall but the most obvious one was that it needed a screen replacement so after I did and tried to turn it on it won’t respond. Can there be something wrong with the battery or something?

It’s hard to know for sure what’s wrong with it, but if you have some extra parts swap them out one by one and see if you can find out what’s wrong. You also might have a bad screen; your device could be booting, but it just dosen’t show it on the screen.
