I installed this yesterday on my V8 PS2, it appears everything was done correctly, checked all connections to make sure cables were properly connected, etc about 10 times. After I put the PS2 back together, it wouldn't even turn on, no lights, no fan or anything. I removed the case and tried to turn it on while it was opened up, still nothing happened. Next thing I did was completely remove all the mod chip parts and cables and put the PS2 back to stock. Still no power. Did the PSU die, the motherboard, or what? Any help is greatly appreciated.
