标题:

iPhone 5S no display but backlight

文本:

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!
