so after i find the resistances, what should I do?

Put them here so largon can tell you the next step. So our cards have the same power regulator chip and the same layout?

Thanks for doing it anyway

Find where the pin marked with number 13 leads on the bigger chip. Also, a better shot of the cropped area with good lighting would be nice.

Measure resistance to ground from these locations:
Pin#7 on the smaller chip (AT-9J?)
Pin#13 on the larger chip (BD-9J?)
