Three Vibration Screen
Phone vibrates and shows sign of life but shows blank screen
@danielife4 I wonder if your "black screen of death" is not a broken display. Just to check this, Power-on the phone and check the power-on sound or motor Vibration. Sound or Vibration is ok? If the answer is yes, replace the display assembly. If it is not, you will have to check the video circuitry on your PCB's according to this flow-sheet
