Hi guys, it’s the second time that happens this strange thing when i work with fallen iPhone 5C. The phone only works with the broken part (lcd with vertical stripes, touch unresponsive etc.) when i try with a new screen, it never turns on, just the backlight when i try to replace it after i have turn it on with the broken screen and replaced with new with the phone turned on. it’s possible that after the fall, the motherboard and the screen will break in a complementary way? which component should I check? Thanks
DISCONNECT THE BATTERY. Remove the LCD and digitizer connections and clean both sides with 99% IPA. Reconnect the cables and then the battery. Before you turn it on, plug it into power and see if it boots itself up. If it doesn’t, then its more than likely a bad screen. It sucks, but bad screens are very common.
