When Ipod finished to charge the battery, I disconnected it from Mac as i have always done. First, it show me the apple logo, then, the display has gone, got to short-circuit and, despite whatever I did, the display still remained white, but my Mac, when I connected it, read it and I could even hear the music, despite the white display.
Well, I had some problem with the rear panel. Only with the Plastic Opening Tools I couldn't open it. I used a strongest tool (a thin piece of iron, took from a pen) and with it, finally I opened the rear panel (scratching a little inside the Ipod and the side of rear panel). To remove it, I spent about 1.30 h. It's so difficult.
Apart the rear panel, the biggest obstacle, the rest of repair is very easy and I spent about 30minutes for replace the display and put it all togheter.
It require a lot of patience, and if you can make you sure to have also a stronger tools than the Plastic Opening Tools (or buy two of those).
