Default HP Omen 15 - short somewhare

Hello.
Have this HP Omen 15 dag35dmbad0 rev d, that have shorted fet on main rail. i repaired main rail and now charging and have power.
But when i push start button, i only hear CLICK and whole power is reseted.
I measure coils and have short on GPU coils and voltages are making only in 3.3 and 5v rails

I removed GPU coils but short looks like on GPU side. Even without coisl power still reset when start button is presed

without GPU and CPU coils power is building in 1.0V , 1.2V 3.3V, 5V rails but still have power reset

i even injected VIN but after start normal currwnt occurs and same power reset, so that reset must be logic not because of short
