Hi,
I was getting 5V with no amperage.
PPBUS was had a 20ohms resistance to ground which lead me to find the shorted part.
I could see that visually U9580 was burnt on a side and a solder ball was lying around.
Took U9850 and PPBUS short is now gone.
However I'm getting 12ohms resistance to ground on PP2V5_NAND_SSD0 which is worrisome.
Can someone confirm what resistance I should be getting on this rail please?
I guess that's game over if the SSD is out.
Is it safe to inject 1-2v on that rail to see what gets warm or too risky for the SSD?
