Sorry for delay . CPU_VR_READY - 1.05 V and CPU_VCCST_PWRGD is 1.02V

U1950: - pin 7 : 3.43V - pin 3: 3.43V

I know there is USB power because it charges my phone and I was able to turn on a UV lamp. PLT_RESET_L = 0.00V.

PRAM RESET but still the same. No signal on external monitor. LCD_HPD_CONN = 0V DP_INT_HPD = 0V In power supply, the current goes from 0.02V up to 0.95A directly.

R7941: - pin 1: 3.43V - pin 2: 0.055V R7941 is in place.

I have cut the trace, I have changed U7201 and still the same.

The macbook entered wet and with sulfate in this area: It has been cleaned, I replace the components and now there is no chime: green - orange led, cpu heats up and there is usb activity. PPBUS_G3H = 12.57V PPDCIN_G3H_ISOL = 20.30V PPDCIN_G3H = 20.30V PP3V42_G3H = 3.43V PPVRTC_G3H = 3.33V...

R7941= 99.8K ohms. Yes, 3V3_S5 is present on L7260.

R7941: - pin 1: 3.43V - pin 2: 0.055V

S5_PWRGD = 0.055V

R5092: - pin 1: 3.40V - pin 2: 3.43V

PCH_DSWVRMEN = 3.23V PM_DSW_PWRGD = 0.00V RTC_RESET_L = 3.33V PCH_SRTCRST_L = 3.33V PCH_INTRUDER_L = 3.07V PCH_INTVRMEN_L = 3.25V PPVRTC_G3_PCH = 3.34V

Yes, PM_SLP_SUS_L = 0.00V. SMC_BATLOW_L = 3.30V.
