Which part should I buy?
Hello everyone out there! I'm new here so bear with me...as a side hobby I fix broken iPhones (broken screens , logic boards, buttons, etc). However recently I accepted the challenge of trying to bring life back to an iPod 4th generation with liquid and fall damage. The situation as it was explained to me involved this particular device getting halfway vertically submerged with the lock button in the water, the user in a panicked state, pulled it out quickly from the water but in doing that it was dropped and the screen popped off. After reparing the mounting for the screen and replacing the lock button I plugged it into my computer and it seemed to work just fine. Every file was intact and it did not appear to be behaving badly at all.But it will refuse to show anything on the screen, when plugging it in and pressing the home button the screen turns on but is blank.... So this all leads to my question of what part I need to buy to fix the thing, originally I was thinking ab entire new logic assembly but after seeing that no file was corrupt I also assumed that there might have been somthing wrong in the screen. So do I get a new screen or new logic board? Thanks so much for the help!
