So i dropped my phone on its back and when i went to use it. it had different colored lines down the whole screen so when i opened the screen and to check if the connectors got disconnected i reconnected them and it still didn’t work pls help me

You damages the screen when you dropped it. Replacing the screen assembly will fix this issue.

The LCD is damaged on the phone, the iPhones have the glass and LCD fused together. So make sure you get the right part, now is the time to get it fixed as the screen prices have come down. If your doing this repair yourself make sure to follow to Ifixit guides use heat, like hair dryer to loosen the adhesvive and go slow!!!
