Hey everyone,
I have a slightly liquid damaged board which initially had no light but there was corrosion around U7501 so I replaced the the chip and also changed capacitors C7500 (one pad was completely destroyed so made a jumper going to Pin 23 of U7501) and C7503. No I have a green which now turns to orange light but still not powering on and nothing warms up either.
I'm basically getting no 5V (besides 1.7 on S5) and no 3V3 RailsThese are some of my readings and I have checked all the rails but nothing else looks damaged and not sure where to go from here.
Many thanks for any help.
Sam
