Xbox 1.1 dead no power

Hi all,

I have a 1.1 motherboard that is dead, I know it's not the psu as I have another 1.1 and it works in that console. Basically I was trying to add LEDs to my case which needs a 12v source. I used a Y splitter on the molex connect for the HDD, it worked for a few mins then the console died and now won't power on?

I have replaced the 5 caps near the psu connector aswell.

 

Thanks

Could be so many things. Is it bios modded or standard. 

Could be a broken track or two.

A bad solder joint.

Crappy mod chip install.

if you could give us some more details we might be able to help.

 

A high quality phot of the board might also help us.

Thanks, it has been tsop flashed. After reading some previous posts on the forum I have tested for continuity and voltages from the pic chip and the front board connector, and all is ok. I have also checked for trace rot, can't see any? 

 

If it helps when I press the power button it makes a single click and the yellow led in the lan port flashes once? I will take some pictures of the boa

A simple check would be to make sure the switch pcb is ok, I had one a while back that was iffy on the connector. 
after that it may get a bit more involved as it could be one of the regulators or the chip that controls the PWON feature.
