Question

i dropped my mobile phone nokia e50 the phone stopped working no letters or anytthing on the LCD itook it apart and put it back together still not working but managed to get the keyboard to make sounds.The LCD is still lit up and is not cracked. Is it worth getting a replacement LCD to fix the phone or is it likely to be another problem?
