My iphone 4 won't turn on at all but i can still put it in recovery mode. Is it really dead?

Dropped my iphone 4 in water. Took it apart, gave it a proposyl alcohol bath and scrubbed the terminals lightly. Let it dry very well for a day or two. Put it back together. The battery got wet as well so i replaced the battery. It will not turn on at all. When i plug it in to the computer it doesn't recognize it at all. But if i hold power + home for 10 seconds, then relese power and just hold home for a few more seconds it puts it in recovery mode and installs drivers for the device on my computer. Still have no display or anything indicating that the phone has turned on. Is my phone done for, or is it possible the screen is just screwed?

No it is not really dead cause if it was you wouldn't be able 2 do anything
