PS2 SCPH-79003 no sound after board trimming

[zolwikwkurwik]

After desoldering "network" and "digital out" and done some trimming of the motherboard on the back, my console don't have sound anymore (or only static hiss).

Does anybody knows what could be wrong or maybe has a schematic of the audio path on the motherboard?
I thought this trimming will be minor, mainly ground points, but the sound stopped working :/

You probably have to relocate 5v to this chip to get it working. I think the "chip" might be the audio pre-amp but it's been a while since I've looked at the PS2 motherboard

Everything works now!! Thanks gman!!

F%ck my motherboard don't have power any more, I think I killed it.
The cable that I soldered between 5V and pin7 of the audio chip somehow by moving the motherboard got detached and was near pin 8 (audio left channel output) or pin 6 (GND) when I was powering up the console.
Is it the end my friend? or maybe the is a fuse that got broken?

I found lot of fuse location for many ps2 motherboards but can't find fuses for 7900x :/

Unfortunate. Shorting voltage to anything is normally not a good sign

It turned out that something else was wrong. I desoldered the power socket and tried to use it with an extantion cable and it turned out that I soldered the ground to wrong pole (when the power supply plug is not inserted both poles are ground, but when you insert the plug one of them disconnects from the ground and I was using that wrong pole).
