Once water damaged, there is lots of things which can go wrong on this phone.

First of all, check the LCD connector (on the iphone logic board of course). Ensure the pins are all clean and not shorted. If a doubt, use a thin needle to clean between the pins.

Then, check if all these pins are well soldered to the board. With the needle try to move (gently) each pin to see it they are correctly attached. If one is moving then you will need to use an iron with a very thin tip to solder it back the pad. Due to the corrosion you will probably have a hard time to solder the pin.

Of course a good magnifier is needed to do a good job.

If the LCD connector is alright then you will need to remove the upper can of the logic board and check for shorted pins.

Good luck!!
