Hi, I have macbook 820-00165 when it came it was dead after putting the power cable and search through thermal camera i found that U1930 were overheating so i have replaced with with another one and the board start turning on but the fan spins for 1 second then switches off.
All the points gives normal values when it turns on for 1 second.
L7320 and L7310: try to display 1.78v and goes off straight away.
L7630: 1.05v
L7430:1.119 v
I have replaced U1950 , q8150 ,u7600,u7400,u7200,u5620, u7820 and SMC but the machine still does the same
Could it be CPU that has issue?
I have tried to power on with SMC bypass but it doesnt power on at all
Generally when you plug the charger in it spins twice for 1 second each time and stays off. If you press power button afterwards it does the same 2 times for 1 second and goes off
Device is not liquid damaged
