hi my name is joe and my xbox 360 power supply had issues so I had another one that was exact but wires were cut so I decided to solder it to the motherboard.. after I finished soldering I shorted the power enable that's attached to the power wires with the 5 volt wire and the yellow light then turns to green letting me know that I now have 12 volts running to it but when I press the power button it will not boot.. any suggestions?? do I have to tie the wire in with the led chip with the xbox power button?? the motherboard is getting all the proper voltage 3.1 or sumthin for the led with the power button so im completely lost on what else to do.. any help would be greatly appreciated thank you..
