Hello guys, I have this one with a non-starting failure, on board diagnostic led 1 lights ok, tested other know working power supply to discard, same behavior.
The board is the 820-2494A
the S5 lines read:
PP1V1_S5_REG -> 1.11V
PP3V3_S5_REG -> 3.37V
PP5V_S5_LDO -> 4.98V
PP12V_S5 -> 12.01V
Seems all ok
This ones not, too high readings, maybe the same culprit:
PGOOD_1V1_S5 -> 3.37V (should be 1.1V?)
5VREG_EN -> 3.37 (should be 5V?)
I was thinking that the U7300 could be the problem, but replaced and all is the same.
Any one could point me some direction? Quite lost with these boards.
Thanks!
