    Hello, sorry for the delay, I was sick. I can get into DFU but revive give "AMRestoreErrorDomain error -1 - Failed to handle message...

    820-01814-A 5V - 0.06amp

    I know what you mean, sorry, indeed it can not be right. so PPBUS_G3H at F6700 = 12.27V PP3V3_G3H_RTC_X at C3100 = 3.37

    Thanks. PPBUS_G3H not shorted but 0V. PPBUS_G3H = .419 & 0V 3V3_G3H_RTC = .400 & 3.376V F8400 is ok F7000 F7001 ok PPDCIN_G3H_CHRG = .529 & 5.14V

    Hello, No sign of life. I see big coil diode mode value is low... Could it be anohter chip than CPU shorted ? PPVBAT_G3H_CONN - Diode .817 PP5V_G3S - Diode .377 PVCCSA_S0_CPU Diode .012 PP3V3_S5 Diode .330 Big Coil L7410 .003 L7420 .003 L7211 .001 L7221 .001 L7231 .001 L7330 .001 LA340 .001...

    A2337 - 820-02016-A - short on PP0V9_ATCRTMR1_VCCA

    I've repalce U7700, short is gone but it doesn't start, stuck on 5 V.With USB-C tool I see 5V, 021V then 0,06 amp then shutdown and start again with my thermal camera I see UF000 getting a little warm.

    ok, caps were ok, short still there. I'll try to swap U7700

    A2337 - 820-02016-A - short on PP0V9_ATCRTMR1_VCCA

    DFU not possible. Actually, I have a short on CAP_PPSPMU_VLDO9, Diode mode = 0.001. As far as I see, there's only two capacitor connetec to this line. Should I try to remove both ?

    A2337 - 820-02016-A - short on PP0V9_ATCRTMR1_VCCA

    Board behavior changed while I was measuring. As soon I measure C7835 CAP_PPSPMU_VLDO9 it stops turning on and off. Board stay on betwen 0.13 and 0.30 amp. I didn' made a mistake( I was always on Volt, no diode mode), not sure why. With thermal camera I see U7700 Pulsing. It's not clear if it's...

    A2337 - 820-02016-A - short on PP0V9_ATCRTMR1_VCCA

    I've compare various points (15) around UF000/100, they have similar value. I am not sure about LDOs, I see PP1V4_LDO_PREREG at 1.39 V on L84E0/2 I see several connection for PP1V5_VLDOINT_MPMU under U8100 but i don't have a test point to measure. I've search around U8100 but i can't see other...

    PPBUS_AON diode mode on F5200/2 = .515 and 12V and drop to 0 when restart PP3V8_AON_VDD_MAIN diode mode on CW10E = .191 and 3.8V stable

    A2337 - 820-02016-A - short on PP0V9_ATCRTMR1_VCCA

    replaced UF000, UF100, UF400, UF500, UF115, UF40 and UF750 and all caps and resistor. When plug USC-C power supply, I get 5V 0,2 amp for 5 seconds then it drop to 0,06 for 2 seconds amp then it stop and restart and does that over and over.

    A2337 - L7800 burned

    Replaced L7800 and U7700 but the issue wasn't there. Problem was on the other side, it was a fautly capacitor on line that connect to U7700.

    A2337 - L7800 burned

    Hi, Macbook air suden death. It was stuck at 5v -0,4 amp. I found L7800 completely burned. I removed it, now it's 5V -0,004 amp. Now I have diode mode .464 PIN1 and .224 PIN2 where L7800 was. Can I replace it and try to power or should I check something else ? Thanks Claude

    A2141 - 820-02037-A - liquid - 20V 0,4 Amp. No short to SSD

    I have a pretty good IR camera. I see U6960 pulsing as well
