Water damaged iPhone 6 no short draws 0.34mA - 0.45mA
We have a water damaged iPhone 6 which I haven't been able to locate a short on.
All the main lines such as VCC_Main, PP5V0_USB. VBATT, PP3V0_NAND, PP1V2 (and SDRAM) are draing normal power when testing for voltages.
PP3V3_ACC draws 0.55V - now I believe this isn't terribly important, however PP1V8 on any cap (good or bad looking) draws 0.05V
Ultrasonic cleansing was first carried out to this.
C1513 is missing and the backlight diode on the PP_LCM_BL_Anode side looks rusted. Out multimeter won't fit here to test.
Just wondering because the PMIC gets silly hot but we also don't have any freeze spray (might look into getting some).
Unsure if this is an outright PMIC failure because it doesn't recognise on iTunes in any way put it does draw current so I don't believe this to be a U2 failure or anything. Would love to know what techniques there are for strange cases like this.
Man y thanks as always everyone.
Esta é uma boa pergunta?
