Chosen Solution
I have replaced the screen of my iPhone 7 plus, and after some attempts to get my touch id working, the phone is no longer turning on. I have noticed a low and constant buzz is coming from the logic board in the area where the power chip is, and this area is getting very hot quickly. This happens whenever I connect the battery. I have replaced the battery, and the issue persists. Is there any way to solve it, or is the logic board dead and must be replaced? Thank you.
