Morning, i was meaning im getting P3v3_S0_EN_L i have 3.3V but now i have 0.41v on P3v3_S0 which is not normal i guess? This is my first macbook experience.
On youtube video he doesnt have video on screen and fan ramp up, he jump a wire from R7382 pin 2 to Q7812 pin 3 because he doesnt have voltage on pin 3 and he get video on screen too. Thats why i tried it....Leave a comment:

Hello every1,
I got a macbook for repair, i have green light + fin spin but no post + no backlight+ no video on screen.
I have vcore, c9796 was corroded and i changed it. Before me, also one person attempt to repair and i saw flux near pch and cpu area. On lvds cable dont have LCD_IG_PWR_E so i dont have any voltage on pin 2,3,4. U9000 i have input 3.3V but no output.
I dont have any light on USB when i plugged in it, no caps lock light either.
I tried PRAM reset nothing changed.
History is, one day owner opened it up... -
