Hi there, I´m repairing an Asus P8H77-i (mini itx motherboard) a forum user gave it to me because it was dead.
I should say that this user tried to do a mod by cutting the external audio port line input. After that, the motherboard won´t power up.
So I desoldered the crappy connector and soldered a new one but the problem persists.
I noticed that It doesn´t make contact between the audio connector´s chassis and the other connectors chassies. I don´t know if this is normal. The other connectors do communicate grounds.
Could it be the audio processor short? should I replace it? does anyone know where to get the schematic for this motherboard?
I have checked the motherboard for blown components but everything seems to be ok (at least visually)
The only thing i know it´s that when I turn it on I can see the green led on the board and the keyboard lights on. But it doesn´t power up.
What do you guys think? should I try replacing the audio processor? bytheway it´s a via vt1708s .
