Trying to repair a 5s - Running into issues with diagnostics

본문:

Hello, I am trying to repair a 5s for a customer.

The phone does not turn on They have been to an iphone repair facility previously who mentioned that it needed a u2 replacement

My diagnostics attempt.

*     The battery was dead,

*     I charged the battery and connected the 4 terminals as shown in the picture and the battery

*     I pressed the power button for about 30 seconds

*     The phone did not turn on and became very hot and 2 generic locations on the board

Is there any other way I can diagnose the board or make the iphone turn on ?

Thanks
