iPhone 6 - irregular backlight flickering
At first...here is a video I made to demonstrate the fault:
And I also want to say at first, that I already changed the Display and the battery but the following problem still exist:
I have a problem with an IPhone 6. There is a 50/50 chance the display starts flickering or not when turning on the display. I think it's the backlight. If it doesn't start to flicker after turning on the display it's all okay...but if it starts flickering after turning on the display, it will not stop until turning off the display.
So it just starts in the moment when the display flashes on and never comes when the display is already on without flickering.
So does anybody has an idea, what's the problem here? What part can I check or which IC /Filter / ..... do I have to change?
I hope someone can help me.
Is this a good question?
