hello
i have a sony f1 mbx-235 that do not power on.

i check it
this motherboard was short by one capacitor on cpu pwm circuit that i remove it, now it is ok.(not short more).
now i have 19v on PQ1(first mosfet) but second mosfet (PQ2) do not transfer the voltage .(both mosfet are ok)
i think the problem is about System scp protect but i do not know it.

is there any body help me.
thanks.
