3GS soaked, dried, still shuts off almost immediately. Suggestions?

My son put my phone in a glass of water. It was SIM side down in about an inch of water for a few hours. I dissembled it and put it in rice for a couple of days. The water wasn't high enough to foul the litmus paper, but the phone was dripping.

The logic board looks decent, except the SIM card looks a little corroded and I don't know how to get to that part of the board.

It starts up with the low battery indicator and then turns off shortly thereafter. I plan to swap out the battery, is there something else I should try? Is there a way to tell what else might be wrong?

Thanks!

Sally,

I think you're on the perfect track so far. Battery is usually the first thing to go. Swap that out and then let us know the results!

One of my coworkers has a box of parts. In the end it's going to need a new LCD and digitizer along with the battery--but it's limping along. Scheduled to get my new battery from ifixit on Thursday.

Thanks for the help, I'd have skipped cleaning the logic board had you not warned me.

Sally, follow this guide to clean your iPhone. It is for a 3G but applies to your phone as well. After you cleaned it nicely, replace the battery and re-evaluate. Not cleaning the logic board will predispose you to some corrosion issues later on. Of course, use these guides to open up your phone. Hope this helps, good luck.

Replaced the digitizer and the LCD. Still no backlight. And, I noticed no WiFi. #6 connector is tight.

Thinking I have more guts than brains, but planning to try a WiFi replacement and a 6r8 coil.
