iPhone 3G: iPhone 3G water damage won't turn on, but apple logo appears

Fri, 08 Jul 2011 11:06:45 -0700

My water bottle opened in by purse and spilled all over my iphone 3G. It has been a year since that happened and I am trying to see if I can fix it.

After the water damage occurred, the phone would not turn on. When I plug it into my computer, it shows the apple logo for about 10 seconds then goes black. I tried resetting it also.

I replaced the battery hoping this would fix the phone. Sadly, it did not. It is still acting the same as before I changed the battery. (I did notice that there were two white dots on the logic board. I was wondering if those were water indicators.)

Should I try to clean the logic board with isopropyl alcohol (>90%)? I'm not really sure how to do this. Do you just disconnect the logic board and apply the alcohol directly to the board with a paint brush?

Are there any replacements that seem obvious to you computer genius'? Maybe the dock connector would need to be replaced?

iPhone 3G: Why is my touch screen not responding?

Fri, 20 Jul 2012 00:46:38 -0700

My daughter's iPhone 3G appears to be working normally - it charges and connects to iTunes fine. You can restore and install new software, you can add media. But the touch screen is not responding. It can't be unlocked at all.

Is it toast?
