the mesure are good, there is no short, do you try another dc adaptor ?
try to do a light reflow for the pch, and see if there is a change.

109Ohm and 94Ohm are alright on the 3.3v and 5v lines?

sorry atsio, it's not normal for 3/5v lines, but i confused with another post that
have 3/5v present,
jonny0404, remove the two big coil L6100 and l6150 and mesure resistance on both side.
