I replaced the charging port and screen.. the phone turned on and Then it timed out and now it won’t come back on… I have been replacing my iPhone parts for years and I don’t know what to do .. I have tried everything , rebooting it, Hooking it up to iTunes . iTunes won’t even pop up when I plug it into pc .. I’m so puzzled

Have you by chance checked the cables inside the iPhone? Sometimes if a cable is not properly plugged in (or even ripped a very tiny bit), it can cause it to not even turn at all. :) I have had people come in for the same issue and it has 90% of the time been cable seating/ripped issues :)
