Hi, I also have the same problem with my iPhone 5. It crashed hardly to the ground and so the backhousing deformed and the screen is destroyed. I ordered a new backhousing and a new display, they are on the way to me. When I actually connect my displayless iPhone 5 to the charger, it makes the charging sound about all 6 seconds. I hope rebuilding it into the new housing with a display attached to it will fix that. Earlier (at my first display replacement) I also connected my displayless iPhone to the charger and the repeating sound wasn't repeating. It started this phenomenon after the crash, so I think the logic board has a fault on any power management section. Maybe it's not getting the needed power to charge the battery. I will measure the voltage on the battery connector of the iPhone while it is attached to the charger to see if the input voltage is okay or not. If the new backhousing and display won't fix it, I will reflow the logic board and tell you if I hadnsuccess or not in this thread. Best...
Hi, today I had the same issue with an iPhone 4S! In my situation it was caused due to a bad quality of the replacement digitizer (incl. LCD). When I looked at the borders of the Digitizer, the left side of the black frame border was a little bit higher than the other side. Due to this quality fault the LCD gets pressure from bottom and it causes white ghost effects on the outlines. Will return it and order another one from another shop. Good luck! Best regards, Tolga
