Hi All, trying to MOD a box with focus video encoder.

Get Fragging with chip turned on but ok with chip disabled.

Done an LPC Diagnostic using this tutorial.http://www.xbox-scene.com/articles/lpc-diag.php.

Im Missing the 3.3V on LPC Pin 9.

Update this is all the voltages i get.

0V - 12 | 11 - 3.3V
3.3V - 10 | 9 - 0V
3.3V - 8 | 7 - 3.3V
5V - 6 | 5 - 3.3V
n/c - 4 | 3 - 0V
0V - 2 | 1 - 0.2V


Can anyone give me a path to trace this back etc or any ideas why its not working.

Help would be gratefully appreciated.

Cheers TX

What chip are you using?

and does LPC #2 show a connection to ground?

1.5 xbox's had the ground removed from pin 2 , and the 3.3 volts removed from pin 9, there is a pic or tutorial on xbox-scene that shows you how to replace the missing ground and 3.3v
