Hi, I have a problem with my iphone after I replaced the LCD without unplugged the battery. I am sure that the problems is on the logic board. These are the information that I got from diagnosing my phone: 1, No short circuit on VCC Main 2. No current draw from charger 3. Boot Current: ~70mA 4. No burnt on components 5. Itunes not detected the phone Is it the tristar? How can I determine which IC is broken?
3.6v on battery connector doesnt sound like tristar and its unlikely for tristar to fail by replacing the screen, maybe long screw damage
