Hello.
I have a iphone 6 with weird value on PP1v8 power rail.
It should show 1,8 V but it is showing 2,70 V . Does anybody have similar issue ?
DCPS show’s 0 Amp’s before powering it up.
PP_VCC_Main - OK
PP_BAT_VCC - OK
DCPS after pressing power button constant 0,22 Amp.

Is it showing image or taking charging current through a usb amp meter

Hei,
From the board right now is missing Tristar, Backlight IC and Display IC.
Should it be still showing normal values on PP1v8?
I would replace the 3 to see what happens after
But still - Shouldnt the PP1v8 still be 1,8 Volt's even if these chips are missing.
What component are you testing for 1v8

Diode mode shows a good value as 339 ( ZXW shows 313), this small differenece cant be issue ?
Measured the cap near to nand.
