No backlight after repair - iPhone 6
I have an iPhone 6 come in that was liquid damaged, no backlight at all. All filters were fine but the FPC was black on the pins. Removed and replaced after reviving the pads. I get half backlight on the right hand side.
All filters have continuity and all pins have continuity to the filters. I have replaced all caps and filters, replaced the driver, the diode and the coil. I have reballed the driver from boards that had other problems and even the pins under the driver had continuity to the filters.
I found a tutorial here, could it be the issue: https://www.youtube.com/watch?v=R8BedLX7...
What's you experience?
Is this a good question?
