Water damaged, won't turn, I had it charged
my phone dropped into water, it won't turn on. I opened the iphone 6s plus took off the shields, and plugged it in. connects to itunes in dfu mode. I then cleaned it throughly. afterwards, i put on new battery and lcd screen but it won't turn on. The Cpu seems to overheat alot. I checked the logic board with the naked eye and couldn't spot any problems. Is the problem with the fpc connector or the pm ic. the charging port works fine due to it begin recognized in itunes or 3utools. Also how can i use the multimeter to determine the problem or diagnotic the logic board in full and what should i use, continuity, resistance, dc, ac or anything else.
Is this a good question?
