VCORE L7210/20 = 0V after 30s maybe CPU is burn?

ok i change Q7900 but always 20V 0,038A I have PPBUS_G3H 13V PPVCCPCH_S5G = 1V PP5VS5=5V

L7900=0,90 like PPBUS_G3H, if I diode mode between PPBUS_G3H and PPVCCPCH_S5G =0

i have C7050 without F7000 13V with F7000 1V, I think it's a short on PPBUS but small short (diode mode 0,250) 3V3_G3H is OK 3,4V

ok i change U7000, same problem

no I don't change U7000, I haven't new one but I have board to keep it but I don't know if U7000 is good. I try and come back

Hi, on this board, I get 20v 0A and ppbus_g3h 1V with no short (diode mode 0,250) At U7000 Aux_det 5v R7020/21/61/62 are ok TBA_HPWR_EN_L 3.4V PM_EN_P3V3_G3H 5V SMC_RESET_R_L / SMC_RESET_R 3.4V SMC_CHGR_INT_L 3.4V CHGR_ACOK 3,3V SMC_RST_IN 0V PD_SMC_CBC_ON 0V R7075 is 5ohms and TBA_VDDA is 5V...

Sorry, PM_BATLOW_L = 0v with original magsafe 2 85W.

YEs 0V, I haven't the battery, only the logic board. No it's an original magsafe 1 85W with original adapter. Is not good? thanks edit: I try with an original magsafe 2 85W, always no led.

i change the SMC, same problem, led green is very low

Hi, i have this board 820-3662 who don't want to boot, I change already because U7190 is short (hole black on the component), I change too U7100, R7101. Now I have PPBUS_G3H, Clean board, no liquid. PP3v3_S5 and PP5v_S5 are present. Missing PM_SLP_S5_L and SMC_S4_WAKESRC_EN which are required to...

ok thanks

No I haven't cpu core voltage, no USB activity. PPVCC_CPU_PH1=PPVCC_CPU_PH2=PPVCC_CPU_PH3=0 VCCINAUX_R=1,8V trackpad force touch work thanks

Hi, this board clean (no liquid), I can restore in DFU the Mac and finish the restore without any error but nothing on the display. PP1V2_AWAKE 1.2V PP1V8_AWAKE 1.8V PP3V3_AWAKE 3.3v PPVDDCPU_AWAKE 0.755v PPVDDCPUSRAM_AWAKE 0.802v PP0V8_SLPS2R 0.800v PP1V8_SLPS2R 1.8v PP1V25_SLPS2R_SMC_AVREF...

no I can't enter in DFU, I don't waste more time, thanks

PP1V8_G3S = 1,8V PP5V_G3S=5V PPBUS_G3=12,6V PP0V9_SSD0=0,9V PPVCC_NAND_SSD0=2,5V PPBUS_G3H_SSD0 = 12,6V With board remove of the top case, and alone on my desk.

OK i have nothing but no short on L9060, L7210, L7400, L7230, L7220, L8410, L8100. Diode mode: L9060=0,355, L7210=0,135, L7400=0,158, L7230=0,135, L7220=0,135, L8410= 0,865, L8100=0,165. I try without audio flex, same problem.

Hi, this Mac fall on the floor, no liquid spill. I have 20V 1,2A normally the Mac charge. But no chime, no display. I can't put the Mac in DFU. I measure PP1V2_AWAKE 1.2V PP1V8_AWAKE 1.8V PP3V3_AWAKE 3.3v PPVDDCPU_AWAKE 0.755v PPVDDCPUSRAM_AWAKE 0.802v PP0V8_SLPS2R 0.800v PP1V8_SLPS2R 1.8v...

Hi, i have this board, seems clean. i have one port USB not work (bottom left). work in charge but not in usb drive, mouse work. What can I do to solve this problem? I don't understand how this port work. thanks
