iPhone SE 2016 taking 5W of power but shows no signs of life.

It’s taking 5W of power but shows no signs of life. Also nothing when connected to a PC. I’ve heard that if your digitiser/screen fails on these models that they will show no signs of life. I’ve opened up the phone and it has the original Apple battery BUT an aftermarket fake screen (That looks to be low quality). So I’m guessing I need to do a screen replacement right?
