PP1V8_S0SW_DFR=1.797V PP3V3_S0SW_DFR=3.313V DFRDRV_12C_SDA=1.797V MIPID_CLK_CONN_P=0.534V... Still not working after changing touch bar 😒

PP0V8_SLPS2R=0.798V stable PP1V1_SLPS2R=1.1V stable PP3V3_G3H_RTC=3.3V stable LDO_RTC =1.5V stable PP1V8_AWAKE=1.8V stable

I can only find two LDO'S LDO_RTC and LDO_CORE

LDO_RTC is stable

I have jumped the PPBUS voltage to pin 44. Still showing folder PP1V8_SSD_COLD=0V PP3V3_2V7_NAND_VCC=0V P1V8_COLD =0V PP1V2_SSD_HOT=0 These voltages are not still available

L9080=0.139 L8102=0.135 L8100=0.142 L7600=0.416 L7220=0.007 L7210=0.007 L7410=0.006 L7420=0.006 L7430=0.006

At J9600 PIN 44 PPVIN_2V7NAND_LB is 2.174V.. Is not upto 2.7V something wrong?

PPBUS_G3H and 3V3_G3H_RTC ARE STABLE

No affected area I have tried another J9600 connector

No SSD detected.. PP3V3_S5=3.3V PP3V3_S4=3.3V STORAGE_EN=3.3V PP3V3_S5_SSD=3.323V PP1V8_SSD_COLD=0V... (diode mode 0.294) PP3V3_2V7_NAND_VCC=0V..(diode mode 0.344) P1V8_COLD =0V... (diode mode 0.292) PP1V2_SSD_HOT=0V...(diode mode 0.316)

T2 heats up to 38°c on thermal camera normal.. L7811-P0V8SLPDDR_SW0 is pulsing from 0V to 0.834V L7806-PVDDCPUAWAKE_SW0 is pulsing from 0V to 0.758V L7816-P0V9SLPDDR_SW0 is pulsing from 0V to 0.9V L7814-P1V1SLPS2R_SW0 is pulsing from 0V to 1.1V

This A1989 came in dead draws 5V found PPBUS_G3H is 6v... i changed U7000 and the system draws 20V 0.00A PPBUS_G3H is 12.31V PP3V3_G3H_RTC is 3.3 PP5V_G3S not present Want to try DFU but not entering DFU and T2 is warming up HELP!!.

Chgr_cso_R_P and chgr_cso_R_N There's no open circuit between them and PPBUS_G3H is 1V CSIN 5V CSIP 0V PBUS_PWR 5v Aux DET 1.25

PPDCIN_G3H_CHGR -5v PP1v8_SLPS2R- 0.265 v CHGR_CSO_p- 1.2v CHGR_CSO_N -0.002v CHGR_AUX_DET-1.2v Resistance on all point ok

Diode mode to ground at PPBUS_G3H is 0.433 F7000 is okay

14 minutes ago Add bookmark #1 The system came in dead found a partial short on PPBUS_G3H_SPKRAMP diode mode reading is 0.0073 and U6500 is getting hot on thermal camera. Short gone but still draws 5.17v 0.0A,PPBUS_G3H is now 1V R7020 has 5V PP3V3_G3H_RTC is 0V.. What should I do next 🤔

Please did you have the boardview and schematics

😥

It won't get to target disk mode before it turns off
