Hello everyone, I hope you're having a nice day!
Currently I'm finding myself stumped with the repair of a WUP-01 motherboard. It was sold to me as not being able to be powered on, and at first i hoped that it was just the fuse, but after measuring through i learned that most of the power rails do not work. I have an identical board to pull parts from so i first replaced all the coils, which gave me the 3.3v network, 1v network and the 3.3v standby network. this made it so the power button came alive again, only to blink when pressed. currently on my board ive pulled and shorted the ic responsible for allowing the other networks once power is pressed to measure correctly, however this is as far as i've been able to get with my research. i've attached the board with the measurments marked. I hope i can find help with what to replace.
Thanks in advance!
