At first it worked fine when I replaced it. Turned it on and worked well. However, after a couple of minutes the screen went black. I can’t see anything but the phone is on. When I plug it in I hear it and when I plug it into the computer iTunes will also read it. I have reconnected all the wires to make sure that a cable didn’t come loose and still nothing. I don’t know what to do
You could have a defective replacement screen. Have you tried to re-install the original, presumably cracked screen? If the old screen works, then return the replacement screen to your supplier for a refund or exchange.
having assumed the following; -you disconnected the battery before the repair -you did not damage the board with your drivers, The following could be the issue.
- Soft reset. (Hold down power, and home button for 15 seconds, or until the device shows you an apple logo.)
- The backlight Disconnected. remove the small black sheet on the LCD Flex that connects to the backlight, and resolder the traces.
- The screen was a lemon, and went bad over time. (does happen)
- The screen wasnt manufactured to OEM standards, and overloaded your GPU. (This can be the screen has fried out, or the GPU damaged.
Try the old screen, if that works you know the new screen is bad. If that doesnt work you have either blown a filter or the lcd driver chip or backlight driver chip depending on if you can actually see anything on the screen or not, or it its just no backlight.
