Sometimes, depending on where you bought it from, new screen assemblies come with the antennas already in them. This is great in that it makes the entire repair easier, but if the supplier provided antennas that are calibrated for a different network, such as you are in Europe but got Antennas that are calibrated for an American CDMA network, then the antennas simply cannot "see" your local network.[br]

Do you still have your original part? If you do, I recommend going back over it in careful detail and checking for any antenna that may be in the original frame (because you didn't need to transfer it over, there was a new one in the frame). If you do find one, dollars to donuts that if you install that antenna and remove the new antenna that came with your screen, it will work properly again.

Also of note, while you're there, check your S-Pen is connecting and charging properly. There are a few different standards and I've had many times where I have to remove the new little adapter and transfer the old one to the new screen assembly.
