Hello everyone!
Two months ago I tried RGH on my Trinity Console but after many attempts I killed it

I want to resuscitate my Xbox and I read a lot of topics about STBY_CLK, HANA, R3B15 and its trace. I checked the resistor and I replaced it but xbox won't turn on. When I try to turn the console, it sounds but it not turn on the leds. The trace seems ok and the tester beeps when I check it. This problem came up when I tried to desolder the STBY_CLK wire.. Nandpro with USB SPI won't recognize the nand. I think the problem is the HANA chip, how can I check this chip?
Thanks a lot and sorry for my bad English but I'm Italian.
