So I’ve checked components leading into and out of U9080
C9081 pin one showing 2.2 ohms and C9091 pin 1 is 4ohm
pp2v5_nand_ssd1 seems empty. Mostly just pads
PP2v5_nand_ssd0 I’ve checked a lot of components on this line and which have this as an output and nothing has shown under 0.3ohm
I’ve also checked components that have ppbus_g3h as an output and no shorts, closest I found was C6470 pin one reading about .8ohm.
should I be more thorough in checking PPBUS_G3H or is there another rail I should be looking
i did clean the...

MacBook Pro A1990 EMC 3359 820-01814-01 no power
When plugged in it stays at 5v
I don’t know what caused the issue but on removing the mobo I saw some corrosion (pictured). This picture was taken after I tried to clean it but it’s still hazy looking.
I checked for shorts in the nearby area
C3501 pin1: 58Kohm
CC749, CC797, and CC796 pin one read about .8ohm
pin 2 on F7000 and F7001 read about 2.2ohm
still very much a newbie so any advice on common faults I should check for would be helpful, thanks -
