Thanks for the answer! And for the circuit diagra.
yes, it was mos (replaced by ior p4086) + D1, D3, R30 (120R instead of 150), R17. Earned! But only one day.Then on the display input V: 00.0V - firmware from Ralim. On the original as if USB is connected

. R21, R20 intact, STM32 input dead ???
I tried different current sources. Please help!

Yes, this is stm32 on this pin circuit, now you can not completely fix it?
