Have this board that's not power up, not sure if i've successfully isolated it but compared to the 820-01521 version, on U7650 after plugging in the power and then removing it, pin 4 (P5VG3S_EN_DLY) has a resistance of 93ohms. On a good board, performing the same test, pin 4 remains at 47k. I've replaced U7650 and R7611 (from 820-01521 sch.) but still getting the same result. Would be safe to say the issue is with U7610 and if so, can i pull it and jumper pins 1 and 4 to confirm this without damaging the board?
