Lcd not working after water damage
I have an iPhone 5 that got wet. I have been working on iphones for sometime so I know how to work on them pretty well. I took it apart and cleaned and dried it as good as I can. Phone powers on, it recognized by itunes, makes sounds, vibrates and responds to touch but I get nothing on the screen. Tried connecting a new screen to the connectors and nothing also. What is wrong?
