Iphone 7 Plus No Picture and Backlight

[platinumsteel]

Hi guys i have a Iphone 7 Plus that gives me no backlight and picture at all.I am 100% sure the phone is booting. It's drawing the correct booting current on my amp meter.I have tried known working screens. I have all my proper diode mode values on all the pins. No shorts. I connected the screen and measured the Display Chestnut PMU IC and below i have put the values i got. Would you be kind enough to check those values and tell me if anything doesn't look right ? I am considering changing the Display Chestnut PMU IC. But wanted to be certain that may be the issue before I do so thanks.

Hi yes i did triple check all resistance values on the FPC connector just like they are on zxw . And i made sure all is fine there.I will try to change the IC tonight and report back if anything changed.
