Water damage - how to diagnose specific problem?
I was given an iphone5s that had dropped into some water. The person said they did not wait for it to dry completely before they attempted to turn it on. The phone does not work and I guess they knew that I like to try and fix things so they gave it to me.
When it is plugged in it will give 2 short vibrations and then sit for a little less than a minute and then give 2 vibrations again. Also, it gives the typical (light-gong) sound of being plugged into a power source after the 2 vibrations.
How do I go about repairing this device? What should I be considering to replace? Screen? Mother board? Power connector? How can I diagnose specific problem hardware issues? (With multimeter?)
In other words, to what extent does water damage the hardware of the iphone?
Thank you very much in advance.
Is this a good question?
