Did you get SMC from donor board, same model?
Can you post some voltages and signals from power on sequence?

NEW, isn't from donor board???
Disconnect battery, use only original Magsafe 2 charger.
Do you get voltage at L7310/20?
If yes, check PLT_RESET_L.

Which coils get voltage now?
Post U1950 voltages.
8.2V at F7140?
8.2V at F7140?
So missing ALL_SYS_PWRGD.
Remove Q8150 and test it again.
There is a problem with PPBUS_G3H also.

What are these pins?
I said to remove Q8150 and check ALL_SYS_PWRGD again...

Why do you need to post all these, even repost, if I asked about one signal???
I saw the value in previous post, just wanted to make you avoid wasting time in the future...
Start removing each power good resistor from ALL_SYS_PWRGD, one by one; R8164/65/66/68.
Be sure R8167 is good; does it have 3V at pin 1?

before i checked what you wrote i noticed u8080 is too hot
I checked the c8080 and c8081 in diode mode, it gives = 0.008
I removed the c8080 and c8081 and then checked it again no problem but c8080 and c8081 pin 1 diode mode, it gives = 0.008
so i changed U8080 and ALL_SYS_PWRGD gives 3,3 voltage
( Q8150 I put it back) but same not turn on it has 0.30A & nothing happens

Now post U1950 voltages.
Looks good.
PLT_RESET_L comes high?
PLT_RESET_L comes high?
Check CPU_VR_READY and CPU_VCCST_PWRGD.
