[Power Button]

ok so I have removed the clock capacitor (leaked) and cleaned everything up.  after putting it back together it will only power on with the eject button, also when I press the eject button again it powers off.

good news is that the dvd drive boots a game disk just fine.

nice XBOX you should TSOP it. The switch could be broken if the xbox is turning on but the button does nothing. I had the same thing happen. replacements on ebay are dirt cheap. I am wondering if trace corrosion could cause this but I doubt it

yeah I was looking to TSOP it but wanted to see if this old thing still worked. well it does but the power/dvd buttons board might be and might not be the issue.  could be a gunked up dvd drive pulling too much power and power cycling the unit.  just now noticed after tearing it apart and putting it back together that the dvd butting power cycles the unit but does not eject the drive...

ok so I put it all back together and the only button that works is the eject button and it shuts off and turns on the unit...

have you ruled everything else out by switching it or manually turning it on?

well, to turn it on I press the CD/DVD eject button. but when I try to turn it off with the power button nothing happens.

 

how do you manually turn it on other than the power button, which it does not turn on the xbox

I have an issue with my Xbox. it seems that the power button is not functional. does anyone have a wiring diagram for that circuit or know what pins to read on the wire bundle?
