I had a broken screen so I replaced it and it worked fine but I realized I forgot the shield that covers the ribbon cables so I opened it back up and reached for my screwdriver and knocked the phone off my work bench and the ribbon cables tore so I ordered a new screen and installed it now the screen won’t turn on but my computer detects it as on (not in recovery mode) but I tried calling it and it won’t ring or vibrate. I tried rebooting it but this didn’t help. Did I &&^& up my logic board or do I just have to get the screen replaced.
This can Backlight is gone. some times when when is on and and lcd is disconnected, backlight can die easliy. Try other lcd if not then is backlight.
