Hi, i have an indigo2 here. On power on fans spins for half a second and then nothing happens. I already recapped the psu with no change in behavior. I tried to trace the pinout of the psu, to try it separately in lab but i can't fiugure out how to power it on... i mean on atx you simply connect the green wire to gnd and it works... but here i can't turn it on.

Can someone help ?

I also tried to trace the power on signal from the switch but got stuck on the motherboard just after the riser connector.

Thank you anyway.

Edit: These are the voltages i get on the power connetors. They only appear for a second except for the stby that are present. Except for the 3.73stby that is only present after a powerup and keep to be present after fail.
