How do you check which component is broken?
I tried to replace my ipad broken screen. Initially when I first switched the broken screen out, the new screen worked, but I didn’t actually sealed it yet cause I wanted to know if it works properly before I finally seal it off. After trying to change the home button too, I plugged in the charging port without the display LCD plugged into the board. And after that I can’t turn it on anymore.
My guess is that some fuse in the tablet is burn or maybe the whole motherboard is burn. Is there any way to check which part of it is burnt?
P.S. There’s no plugin sound when I plug in the lighting cable to my computer.
Thanks for the advices in advance.
