Okay, sorry about that.
No physical resistors present. I reflowed U7800 and U1200, no change.
I get PP3V3_G3H_T at U8250 but nothing on SENSOR_PWR_EN or PP3V3_G3SSW_SNS.
Replace U8250?
I don't exactly know the place of this voltage in power sequence; may appear later.
Give a try lifting one side the GPU core coils (all).
Not sure for this board, but 01700 stays on and chimes in such case.
This board never chimed at all. The only thing that comes to mind is the onboard RAM may be the problem area. I have decided to call it quits on this repair but I sincerley really appreciate your ongoing help and support.
