Hi,
does anyone think or know if it's possbile to put a t 4302 instead of a mtd 3302 (the power mosfet on the motherboard). Their caractéristics can be found with this links. I saw that the v1.1+ mb have less capacitors and the power. I've tried but it doesn't work. The box boots 3 times and frags.... :(

A frag indicates that the MB may be working fine.

The Red/Green is activated by the PIC, so it's getting proper power.

E.G. so is the motherboard.

something stranger, I tried to remove a mtd3302 from a motherboard that used to work (not so fine but it could boot and play games for a short time).
I soldered the componant back to the motherboard and now I've got the same problem: the xbox frags just like the other one. Isn't that weird ? I'm going to mesure the voltage to see if something's different from a normaly working box.
