All good, I have a problem with this board, and if you can help me, thanks in advance:
The board turns on by itself, does not emit video or hums, I started to see the transistor that drives the inserted processor (h_sktocc) and that was not a problem, the voltages are ok even when the signal (pwrbtn) is 3.3v high and the reset signal is also high (rstcon) fpanel.
By measuring in EC nuvoton, I realized that rsmrst is high (3.3V) on the plate, I know it shouldn't be high, what should I do?
another thing: when motherboard power by itself, the voltajes for example 12v 5v. is oscilating! to 12v(9v-12v) for 10-15seconds..then they stabilize
thanks again
