I got my iPod classic wet while washing the car and needed to replace the screen as it was flickering at first, then completely went blank after a couple hours.
It went really well! I followed the step by step procedure on the website and it all fell into place. I didn't have the prescribed tools, so made my own up. I used the straw on a WD40 can as a tool to help me remove some of the flat ribbon wires and it worked a treat!
Take your time, and don't have any distractions. I told my Mrs to go to the pub!
