Hi.
I have an A1990 820-01041-07 with no power.
The mac had contact with a bit of water, and U9080 area was a bit oxidated, and the area near UB300 also seamed to be a bit oxidated (very few signs), but because it has 20V I didn't replaced it.
I've replaced RB258 because it was a bit oxidated, and U9080 because that area also had a bit of signs of oxidation.
I have 20V on ampmeter, and the ampeter progressive reaches 0.255A and then it reboots.
I can't see anything else damaged, and couldn't find anything shorted.
Do you have any idea to where I should focus?
Can you help?
