So I open my phone (unplugging the the flex cable stuff) then I accidently turn on the phone then I replig everything now the phone turn on..
Check for long screw damageCheck if it’s recognised on iTunes or a charger (ie may be on but u have no display or no backlight)Check for damage around the lcd connectors on the screen and the boardCheck for damage on components around the screen connector on the boardTry the old screenTry the old or new screen without plugging in the front camera flex or the home button flex to rule out one or the otherShine a torch on the screen see if u can see a dim apple logo when the phone is starting up (blown backlight) * I assume u already tried restarting the phone ie disconnecting the battery or holding down the home and power buttons…Lol should have a flow chart
