Mensagem original de: service ,
I would take it back to where you got it fixed and explain this all to them. Sounds like they may have messed something up in the repair process. Not positive wihtout seeing it, but From changing a screen you don't mess with anything as far as cell service , at least you shouldn't Besides the sim. you could try putting it in Airplane Mode and taking it back out, or taking out the sim and re seating it back in place, see if you service picks up then. If it is saying no service that can drain the battery from constantly searching. I would definitely take it back to the repair shop and ask that the tech double check his work.
