Change LCD and backlight ic, still black screen when powered on
I broke the screen on my iPhone, then replaced it and now the apple logo pops up for a split second then then screen goes black but still boots up. So I changed the backlight ic and still have the issue. I have also replaced the battery. I Am at a loss to what the problem may be. I have fixed many iPhones as I am a cell phone repair tech but this one has me stumped. What else can I try?
