Did you swap the logic board from the old drive to the new drive if not then that's the problem. If you did that and it still don't read disc it could be a dirty or bad lens. Leave the metal top off and watch what it's doing if you see red on the lazer when you enter a DVD then it works if you see blu it's working on the blu ray side. If you see both of them and that don't work then try to go to the secret menu and do option 3 then option 4.
