Assuming the computer was working before you replaced the dvd drive and the topcase the next step would be to disconnect the dvd drive and see what happens when you try to turn on the computer. If this does not work and the topcase was connected when you tried to start the computer with the logic board pins remove the topcase and try again. Almost always when this kind of problem happens it has something to do with what you changed. Good luck.
