Screen is black and unresponsive
After droping my phone, the screen cracked and went completely white but the screen was still recognizing my touch and i could hear the clicking on the keyboard, after replacing the broken screen with a new digitizer, glass, and lcd my iphone does not recognize my touch and the screen is completely black, in this whole process i payed close attention to cables 1,2,3 to prevent any sort of damage. i also put the old lcd with the new glass and it recognized my touch but the white screen was the biggest issue to solve, so did i get a defective lcd and digitizer? which i find unlikely or did i fry some other component inside?
Cable #2 which manages the LCD often detaches during reassembly (I have done this a hundred times and it still occasionally pops off on me) and could be the culprit if you know the phone is turning on. I would try turning the phone on while it is disassembled and holding down cable #2 with a finger.
i have the same issue, my screen never died, the phone was ran over, it did not get smashed, the screen had a protector so no real damage. The only thing that didn't work with the phone was the "home" button. I decided to open it up to see how much of a chore it would be to fix the home button. Now i get nothing on the screen. No touch response or anything, the phone is detectable by itunes, i can receive calls/texts, but i can't pick it up or see the screen. I've check several times the connection while putting it back together, I've checked the ribon cables if there is any damage, and I see none. What is left that could be a problem?
