iPhone 5S no display but backlight
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!
Is this a good question?
