Xbox OG V1.6 Motherboard Power Buttom Traces - Power Buttom not Working

[Carlos81]

Hello, my name is Carlos, I have an original xbox, I am connecting it by the eject button, because the power button is not working, when analyzing the tracks under the board I did not find corrosion, could someone please provide me with the scheme for measuring the points contact of the four tracks? so I can really check if they are broken.

Take a look at: SICKmods : Xbox1 > Power Eject Pinouts (archive.org)

There are an images showing the endpoints to measure for continuity of the power and eject signals for v1.0/1.1, 1.2-1.4; there are no 1.5 Xboxes and v1.6 .revisions.

friend thanks but the trails on top of the board and the resistors are ok, but I need the wiring diagram of the traces on the bottom of the board.

If you measure continuity between the two violet then two cyan colored locations on the motherboard, you have all you need.

I measured with the multimeter, all points are connected. Could it be the unlocking chip causing the problem?

Have you tested the voltages at the 20 pin power connector.

 

Also you can try to momentary short the blue or the purple spots at the Xyclops chip to ground ( the Metal shield )and see if the Xbox turns on.
