Trinity won't start

[Dadko]

Hello

Some old customer came back after 2 years. His console won't start up. There is't even any beep sound. Console seems to be totally dead.

I tried new power supply. It didn't help
I wanted to reflash nand, but I am getting Can not Continue error
There is 5V on CR4
I assume there might be broken some mosfet, but I don't know where to start measure. Can somebody guide me where to start?

Thank you

What motherboard is it? It could be a corrupted nand chip or ever a dead southbridge. Or like you said there could be a blown midget somewhere.

Try applying pressure so the southbridge when powering on.

Might also try a different rol module just to be safe. Those being bad have cause this problem as well.
