screen not working after I replaced it with a new one

So about a year ago i dropped my phone in water. I put it in rice, it dried out and it was working. Then the screen started going black little by little. It stopped completely working after about a month or two. I bought a replacement screen, put it on and it does not turn on. The phone vibrates and all but the screen stays off. I force rebooted it a few times already and tried everything else i saw could help. Any other ideas?
