You will need to take the phone apart and clean it first. Below is the tear down instructions. [guide|6610] Once you have the board out use a toothbrush and isopropyl alcohol to scrub any corrosion from the board and they connectors that attach to it. Reassemble and see if it works. If the display does not come on you will need to try a new display to see if it comes on then. If the devices display still does not function with a new display then the board has suffered some damage that would require a special equipment like soldering iron. Even with this equipment and the appropriate skills it's not a guarantee that it can be repaired.
