The underside of the headphone module, and what resides beneath.
Unfortunately, this is as far as I dare to go. It is possible to lift the logic board from the screen and interface board, but I'm not brave enough. Mainly because it's held together by a very short ribbon cable that looks very difficult to reattach. Most possible repairs for this device need not go that far anyway. If you have one of these and the interface or screen is non-functional, it's probably actually a better idea to just invest in a new MP3 player.
I will, however, give you a glimpse of the other side...
