Problem with screen replacement image too high /\ components problem?

It's an A1509 ipod (16GB, no camera)

A picture is worth a thousand words so you'd understand the problem ... I haven't tried to restore or else by itunes because I can't unlock the device (because desactivated) to authorize/rely the ipod (I dunno how to say in english when it's the first time you connect device to a computer) and home button isn't working anymore ^^ thanks for help !

the touch screen seems to be ok because when i press in the right place of cancel button in the bottom it works ....

the vertical seems to be too high (well a zoom but only on the height ...)

Ok, my friend told me that it wasn't drop in water, but may be some mud on it, I've found a little dirt over some components, I've "cleaned" with a needle ... and turn on again, not helped ... :P :( help please !
