Do you run with the iPod, work out while wearing it, or live in an extremely humid climate? The reason that you can only see the screen in sunlight is because the backlight is out, which is a light located behind the screen that lights it up. I have had many iPod nanos have this problem, and they are all liquid damage to the backlight circuitry on the logic board. The problem is, if you sweat on the iPod or move from a cool, dry indoor environment, into a hot humid one quickly, moisture will get inside. You can try disassembling the iPod and taking out the logic board, then cleaning it with isopropyl and a small brush(gently). This may remove then corrosion off the board ad save the iPod, but remember to be very carful, since the components are very delicate and can easily be broken.
Hope this Helps
