recently, while watching the rocky horror picture show, my headphone jack stopped functioning properly. i,d like to take it apart to see what's wrong, but i don't know how to get it open. i even unscrewed it to see what the problem was, and the damn thing STILL won't come apart! can anyone help me figure this out? i think all that's wrong is the solder connecting the jack to the tablet is loose, but i need to be able to open it and look inside to see.
