+1/ Hard reboot the phone: press and hold power button + home button for ~12 seconds, then restart;
2/ Power cycle + clean and re-seat the screen cables: disconnect the battery connector (DO NOT remove the battery), clean the screen connectors on the board and the screen cables using a cotton swab dipped in 90%+ isopropyl alcohol. Do not let the alcohol touch the screen. With battery still disconnected, press and hold power button for ~15 seconds, then reconnect the battery, gently re-seat the screen cables make sure they are properly connected. Reboot your phone.
3/ If no change after 1 and 2, try a new known good screen. You could have pulled on the screen cables and damaged them.

4/ If 1,2, and 3 do not solve it then you may have logic board damage. It could be ESD that fried something, or long-screw damage, or pry mistake if you damaged something around the screen connectors (examine around them using a good magnifying glass, look for anything broken/damaged/part torn).
Start troubleshooting and tell us what you find out!
