820-00165 not turning on

Post diode mode to ground at L7630.

0.215V scale diode.

comparing another board I present 0.201V diod scale.

Troquei o u7600, L7630 0.18V. same defect.

Check, or replace components around U7600.

replaces everyone around, I found a broken trail r7641.
Still no solution. This is difficult.
L7430 and L7630 0V, missing pp5v_s0, PM_SLP_Sx_L missing.

Any reason to quote an entire post visible few centimeters above???

Post U8080 voltages.

"PM_SLP_Sx_L missing"
What happened?
You had even PM_SLP_S3_L present before...

replaces the u7400 and u7600, in the tests the tensions were absent.

u8080, all 0V pins.

PP5V_S4RS3 there is a pulse.
I'm frustrated

Something happened, you did something wrong.
You had stable voltages...
