Need help identify problem component or next steps to test.
The motherboard isn't working there is no power indicator light and overall no power on.
However, I have identified multiple 19v, 14, 11v, 10v and 5v points across the board but nothing that goes below 5v.
No I have reached a part of the board where I think there is a problem.
Multiple components (buck converters?) that are ramping up voltage. I have marked all the details in the picture, the problem is at the pink components - they are ramping up over of a few minutes from 0v to 4v and beyond.
Some other notes: everything north of the problem area has stable voltage mostly around the 19v, 16v mark. South is all stable with a lot 0v spots and 19v, 16v,11v and 5v.
I am now not sure what the problem component is and what next steps I can take as it goes beyond my capability.
Any pointers are appreciated!
