Hi…….. I replace my iPhone 6 screen and when i press power button there was no display the screen black
Go back to this guide and double check that you did everything correctly. A common problem is forgetting to disconnect the battery before removing the screen. In some cases you can blow the backlight circuit. *Double check your connections *Connect your phone to a computer to see if itunes recognizes it. If it doesn’t, inspect the connectors for damage or loose/missing components next to them *Check to see if the screen works by shining a flashlight to see if there is a dim image. That would be indicative of a blown backlight circuit. This is not a DIY fix and requires micro-soldering. Check this out and get back to us.
