Basically i removed my screen and before i screw everything back i checked if the screen is working and it did worked. Then i screwed everything back and i tried to turn it on and i get nothing . i plugged it to my pc and it’s shows my phone in iTunes and it’s charging. I have no sound and vibration. Please help me what should i do and sorry for my bad English .

  1. Check the display sockets
  2. Try a new screen
  3. If not, check if the plugs are damaged
  4. If the connectors are damaged, you need to go to an expert repairer

I’m guessing long screw damage after putting a longer screw than required on one of the few screws that screw onto the metal plate to the logic board for the screen connectors.
