820-01700 16" MBP A2141 dont turn on

Hi, just this device came in

20V draw with batterie

no dong, no display


checked the power sequenz from repair wiki

https://repair.wiki/w/A2141_2019_16%22_MacBook_Pro

PMU_CLK32K_PCH is ok
PMU_ACTIVE_READY is 1.8V
PMU_ONOF_L is 3.3V
PP3V3_S5, PP1V8_S5 is 0V

R8013 Pin1 has a nice sinus wave

so it seems me the problem could be the PMU, what do you think?

Any history available?

Be aware, this machine requires 96, or 140W charger.
Do you get expected SLPS2R and AWAKE voltages?
It is recognized into DFU?

I use a laboratory power supply , until now that was good for all a2141

PP1V8_SLPS2R 1.81V
PP1V1_SLPS2R 1.11V
PP0V8_SLPS2R 0.81V

PP1V8_AWAKE 1.8V
PP3V3_AWAKE 3.36V
PPVDDCPUSRAM_AWAKE 0.81V
PP1V2_AWAKE 1.21V

the history is it stopped from one day top the other

I was sure that I had tried a recognition in DFU mode. Now, for the sake of order, I tried it again and how cool, it says RECOVERY on the display. Then I carried out all the necessary steps. The case can be closed. The problem has been solved.

Thanks to 2informations that I had not yet desoldered the PMU.
