It’s the display. iPhone 7 and up don’t have a physical home button so in the instance that you connect the flex cable that runs the home button you can run into this issue. Doesn’t happen all the time but with some after market displays the button isn’t coded properly. Meaning your phone just can’t process the fact that you have a home button and the software never loads.

Have you tried reconnecting the broken screen?

Do you have another screen to test it with?

Yes sir I connected the old screen but it got the same issue. "stuck in Apple logo and the logic board get really hot.

When I see the logic board get really really hot I disconnect the battery cable, because I don't want to burn the phone. I'm trying to be really careful.

When you replaced the screen originally, did you unplug the battery? I sounds like something is fried.

disconnect all the ribbons and just plug in the lcd connector and the battery and see if this lets the phone boot to the main screen, if not and the phone is still overheating try and locate where most of the heat is coming from
