iPhone 6P screen is blurred, how to do it?
Received an iPhone 6P from our customer, the customer said the motherboard is damaged, the problem is in the touch part of the display, the touch is not responding. First of all, what should we do?
After install the motherboard to test, we found it's blurred screen, like a snowflake flash, and then black screen, reboot and test again but completely did not show anything on screen.
But from the fault mark inference should be able to cross the interface but not touch, however, it can not display now, we judge that the problem in the display part of the probability is greater.
The display base is nice and the ground resistance is measured normal with Fluke digital multimeterhttp://www.vipfixphone.com/digital-multimeter-repair-136_88/fluke-15b-high-performance-digital-multimeter-for-mobile-phone-repairs-fixphone-3425.htm. After careful observation, it is found that the shield cover of the main CPU has a little pressure and cracks at the solder joint.
Remove the shield, the fault point is more intuitive under Stereo Zoom Microscope, there is a pin of the display IC U1501 is crushed.
Replace a good iPhone 6P display IC and install to test, problem is solved now.
