No difference tried in another complete casing

Just tried DFU System displays while installing system and give error 9 And shutdown

Board shows apple logo and shutdown PPBUS_G3H =12.60V PP5V_G3S =5.1V PP3V3_G3S=0.422V PP3V3_G3S_EN=1.8V ... Help 🙏 ....

P_IN=5.17V AUX_DET=is between 1.1and 1.2V VDDA/P=5.1V SMC_RST_IN=0V PBUS=1.1v EN_MVR=5.1V AUX_OK=0.705 A/BMON=0V I knocked off R5275 and C5257 they are corroded

Yes still good.

The board draws 5.17v 0.00A I found short on PPBUS_SPKRAMP and knocked off CR636 short gone... still no power PPBUS_AON=0V 3v8_AON=0V PP1V5_UPC1_LDO_CORE=1.5V PP3V3_UPC1_LDO=3.3V PP1V5_UPC0_LDO_CORE=0V PP3V3_UPC0_LDO=0V. And board still draws 5.17v 0.00A

PPBUS_G3H is 8.59v PP3V3_S5 IS 3.3V PPVRTC IS 3.42V ALL_SYS_PWRGD IS 0V PP5V_S4RS3 IS 0V.. does this board needs battery to power on ?

With both charger and battery connected PPBUS_G3H is 9.02volts

UPC_I2C_INT_L is high(1.8)? Flickers btw 0.9 to1.79 and 1.810 when charger is plugged in with battery connected

🤓 I replaced DF622 and DF602 boom 💥 it works

No voltage shown at the type c ammeter. The board is very clean no water damage or corroded components and no voltage present at all on the board. I have tried another type c charging ports. HELP

The board is very clean 👌 no corrosion. PPBUS_G3H=12.26v pulsing to 11.16v PP3V3_G3H= 3.3v pulsing to 2.8v. The rest power rails not present, and no voltages on big coils around u7800.

I've gotten 96W charger, The board does not turn on at all with charger alone it draws 20.56v and 0.08mA without battery plugged in. Draws 20.56v and 4.54A then goes back to 0.00mA with battery connected

I tested it with original 96W now,it draws 20v and 3.06A. It chimes but no display with high fan spin

No..until I press the DFU combination keys.
