Hello people!

I have here iPhone 6plus with water damage. First after power button, had 0.8A constant current. replaced PMIC - current back to normal. now after button press - current = 0.2A

all voltages present, except PP_GPU. resistance on GPU ~50 ohm.
checked with this video --> youtube --> /watch?v=GHw1WX-CC_Y

all 3 NAND voltages present and proper.
any solutions ?

thanks!

PP1V8_SDRAM has 10 ohm resistance, but voltage is proper. I suppose this is half shorted somewhere.
