Hello, Happy to send my first message on this forum! :) So my request is about an iPhone 5S. He start completely but nothing are display and the backlight still works. L19 coil has a little water damage, the pin 1 of L19 probably short to the gnd through the metal plate. But he seems no dead, how can I test it properly? And are there any other parts to test in this area of the logicboard known for display issues? Can this coil cause that or it’s more like a death of the U3 LCD controller chip ? Help me understand please.. Thanks in advance!
Hi This problem is so common in iPhone 5s and iPhone SE. Replace the touch ic (U15) and the phone will display again.
