Chosen Solution

Hello everybody, I got an iPhone 7 Plus, which felt down from an carousel. From this point on, the phone doesnt work anymore. I replaced battery, LCD screen & dock connector, but I get the following reaction: The logicboard gets very very hot but it the screen wont turn on and just keeps black. It also cant be found on iTunes. I can turn it on by Power-Button, but thats all I can do. I only know by the temperature, that it turn on. Maybe anyone of you have a suggestion for me, what I can try. Best Regards

It needs looking at by a logic board specialist. The heat indicates an electrical short somewhere on the logic board.
