Chosen Solution
Hi everyone, i was replacing the screen on an iPhone 6, i replaced the screen, and then i tried the screen with the iPhone open, everything was working except the home button and when i click it the iPhone just died and it wont turn on Again. When i try to solve the problem i noticed the cable of the home button wasnt correctly in place. During the procedure i didnt disconnected the battery cable. Now the phone wont turn on and neither is recognised by the PC when i try to connect it.
Try disconnecting the battery and plug it back in again and see if you can power on. Otherwise if that does not work try unplugging the home button extension cable near the screen connectors and try turning on without that.
It sounds like the backlight is dead. Do you see anything on the screen if you try point a flashlight towards it?
