I have a 2019 16" MBP (820-01700-5) that will not power on. 20V 0A. T2 is not booting and is not recognized by Configurator 2 in normal or jumpered DFU mode. I strongly suspect a short, but cannot find one.
PPBUS_G3H - 12.3V
PP3v3_G3H_RTC - 3.3V
PP3V3_G3H - 3.3V
PP1V8_SLP2R - 1.8V
PP1V1_SLPS2R - 1.1V
PP0V8SLPS2R - 0.8V
PPVDDCPUSRAM_AWAKE - present
PPVDDCPU_AWAKE - present
PP1V2_AWAKE - present
PMU_SYS_ALIVE - present
PMU_COLD_RESET_L - present
PMU_ONOFF_L - present
I2C_PWR_SCL - not short
I2C_PWR_SDA - not short
PP2V5_NAND_SSD0 - not short
PP2V5_NAND_SSD1 - not short
All power attempts done with battery and BMU cable connected. Both were replaced by Apple recently. I also replaced u7000 and checked all surrounding resistors and caps. I'm fearing the T2 itself is bad. Have I missed anything? Any help appreciated.
