How do you expect someone to help you fix the problem if you have not posted any code, or even reported precisely what is or is not working ? If you on the other hand are requesting a ready-to-use code, this is not the right way. You should first try to turn ON at least one of the segments of the display, and only after it this step, in the case of nothing works, you should ask for help. In short, with the information you have provided up to now, it is not possible to help you.
