Phone keeps turning off and won't turn on after screen replacement

I recently changed the screen on my iPhone with a 3rd party LCD screen as my old factory screen was severely cracked and displayed green all over. After I changed my screen with great care, I started encountering issues the same day where my phone would randomly turn off within minutes (and sometimes instantly) and wouldn’t turn on unless I plugged it in to charge, even though my battery was fully charged (for context, I replaced + calibrated my battery a week prior while using the original screen and encountered no problems).
I’ve noticed that sometimes, tapping it or setting it down will cause it to turn off. It will eventually turn itself off randomly, even if held in my hand or resting on a table, with the frequency increasing the more I turn it on and it dying until I leave it to rest. I double-checked all connections during the repair and tested the phone before reassembling to ensure everything works, with no issues. I had the battery unplugged while connecting the screen to ensure no discharge or damage. My first thought was the battery, but the battery is brand new and did not pose any symptoms or problems prior to me replacing the screen.
Why is this happening? I’ve heard some theories about components making direct contact with other parts of the phone’s internals which could cause problems. The screen I bought, while 3rd party and LCD, is from a reputable manufacturer (as far as 3rd party parts go), was bought brand new, and from a trustworthy seller. The screen is fully functional, so I’m less inclined to believe the screen is defective.
