It really depend on what is wrong with it. Could be a wire just came loose, OR it could be a board broke, it's difficult to tell what is wrong. Is the device working, but the screen just won't come on? That is can it receive calls? Does the led come on when you try to power it on, does it make any beeps when it's trying to start up? Do you think you know what piece you need the replace? Or do you plan to just start replacing stuff till it starts working?
