iPhone6P手机屏幕发暗，有显示无背光，显微镜下一目了然直接秒杀2019-07-18 15:10·迅维手机维修培训接修客户一台iPhone6P，描述的故障是手机暗屏，背光灯不亮。这种现象一般是背光供电有问题，阴阳屏的话是背光回路出问题导致的。显微镜下观察主板有维修过的痕迹，背光供电和背光回路上的电感被短接过。测量座子阻值都正常，说明座子相连的电路没有断线。拆开CPU屏蔽罩，背光芯片和电感二极管也被动过。拆右边背光芯片测量对地值时发现D1脚PP_LCM_BL34_ANODE无穷大，正常阻值是500多才对，打开鑫智造查找相连的元件。与D1脚相连的有C1588、C1587、二极管D1589，测量C1588没有阻值，测C1587是有阻值的，测C1587到D1脚焊盘无穷大，说明断线了。直接从C1587飞线到D1脚，开机测试发现有背光了但是阴阳屏。拆左边背光芯片测焊盘B2脚对地值发现45_AP_TO_PMU_AND_BL_DWI_CLK无穷大，此脚相连到右边的背光CPU和电源，需要飞线。飞完线进系统测试，背光故障修复了，但机器完全没有触摸。测黑白触摸供电都正常，拆下黑触摸发现触摸M1脚掉点了，补回MI脚。进系统测试，触摸功能正常，维修结束。有爱好维修的小伙伴，点击关注我们哟！了解更多
