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?

could be corroded pins not making contact or just nearby there are a few small components/resistors/capacitors (technical people will know which one it is) which are the most likely to be damaged by a short. Is there any faint image if you turn the phone to one side or shine a bright light on the screen? could be backlight or somewhere on that path. backlight solution

Try to wash the connectors, or wash the entire logic board with 99% alcohol. This worked once for my Iphone 5 that was water damaged.
Never had display problems, but it fixed some other weird problems with my 5 after the water accident.
I bought a bottle of Isopropanol 99% and used a tooth brush gently cleaning the entire logic board. I also put the logic board for some minutes in a alchol bath.
Remember to let it dry properly before assembling again.
Maybe alot of work, but it can be worth a try to wash the display\ lcd connectors, both the connector on the logic board and the two on the screen.
Hope this helps.
