re:
I noticed some corrosion on the logic board and connectors so I decided to follow one of those YouTube videos that show how to repair an iPhone which has gotten wet. As I've stated before though, the iPhone is recognized in iTunes, vibrator turns on and off when toggling the switch and I can hear the camera shutter sound when I press the home and power button together to take a screen image.
With that said, I took the phone apart yet again. This time also removing the metal covers that go over the processor and other chips. Dipped the logic board in a small plastic container with some 70% alcohol. I let it sit there for a few minutes and the used a brand new toothbrush to brush around the logic board and connectors and plugs and such. Made sure to dry it good and also used a can of compressed air to make sure I got all moisture out. After this I let it sit for a good 30 minutes and then proceeded to put everything back together.
iPhone does the same exact thing as it's been doing and it's still recognized in iTunes. But still nothing on the screen except that bright white/bluish image in the center. Backlight turns on, but still no actual display of the Apple logo or Home screen.
