Water damage. Flickering screen...

Okay, so I just bought an iPhone 4 with water damage. It finally turns on, I got it to restore and seems to work perfect. But it's not usable some the screen won't work. I figured the LCD screen was shot so I used a screen I had in my invetory and when I unlock the phone via slide to unlock, the screen briefly flickers and then is black again. Anyone have any ideas of how to fix this? All I can think is the logic board... :(

If you have tested the water damaged iPhone with a new known working LCD and it is still not working then unfortunately your logic board has become a victim of liquid damage :(

You can try re-seating the connections if you haven't already, however we all know how much electrical components loooooooove liquid.

My advice is to either return the iPhone to whoever you got it off, search for a replacement logic board on eBay or wait until the beautiful iPhone 5 is released.
