After water damage, after cleaning, don't turn on and don't charge
I have a big problem. I've buy an iphone 4 at ebay. The seller says, that the iphone was dropped in a toilett.
First one i took the logic board and cleaned it in a bath of an isopropanol approx 70 % and in an electrical cleaner called "KONTAKT WL Universal Reiniger für die Elektronik universal cleaner for electronic.
After this i assembled the components and my phone is do nothing.
- I can`t turn it on
- no charge
- no initialize with itunes
but i know that the display touch are allready. I cant see any kinds of corrosion ore damaged contacts. Only that can i see is that the soldering joints are a little bit darker as a new logic board.
- switch power on / off is OK
- Battery is ok
- Display / touch are ok
- cable to charge is ok
One thing what i can see is, that one smd component near the headphone jack connector was one contact detached.
Who can tell me for what that component is? I dont think that can solve my problem. I think it must be near the power supply.
Please help me!!! I don`t know what else i can do.
I offer my thanks in advance.
the logic board on the top is the board with no function. the upper board was only to check the components with the top one.
Is this a good question?
