Xbox 360 Shorten While Powered On
« on: November 04, 2010, 11:52:00 AM »
Looks like I shorted my xenon while it was powered on. Had the motherboard on carpet as I was testing 12V fan temps. Then a piece of cable (two wires exposed) fell onto the mb where I've marked it:

The box turned off immediately and PSU red light came on. Replugged everything and the PSU turns red as soon as I put the cable in all the way. It works fine with the second console.

No sparks or smoke when it happened, all the components are intact. I guess it's pretty much done since this happened while it was turned on?

In b4 "lol dumbass powering on and exposed mobo and dropping exposed wires on it"

Can post actual pics of the area if anyone is interested.

Not much of an expert but you've probably blown a mosfet or something, and powering an exposed mobo on your carpet? That sounds a bit dodgy.

OK, maybe you are lucky and it is not the MOSFETs. I see you have some blown and grown Capacitors there. First you must replace those before you proceed to further testing. They are obvious with naked eye. I marked them in green for you as follows:

Check if there are more in this bad shape.

This isn't an image of his board. (IMG:style_emoticons/default/sad.gif)

A real one would be good though.

First of all, the thermal paste you are using is spilled all over the place. Clean it and apply a proper amount of it and prefer to use arctic silver 5 or better.

Secondly, I don't see any burned capacitor, so what you have to do is to restore your mainboard to the state before you started modding. Remove the cables, clean the soldering, clean the board from dirt etc., re-apply x-clamps and try to turn it on once more. If the result is still the same, then start checking MOSFETs.
