You can try this TIP #1 iPod universal TEST MODE! Press Menu and the center Select button at the same time and hold (like a soft reset) however once the Apple Logo appears release and press BOTH the BACK (|<<) and the Select (center) and hold till the drive spins up. If you did it correct the apple logo will reverse (flip) and go into the 3 in 1 or 5 in 1 test use >>| or Menu to scroll thru all the test and options...you can rune the 3-1 or 5-1 test and check many major components, USB, HDD, Audio/Video. Then just order and replace the missing damaged parts. As for your update, the sad (unhappy) face means dead ipod, in my experience it is usually the HD that has probably failed. Good Luck.
