Xbox Buttons make noise, nothing else.

Hello all,

I have a Xbox 360 Slim Model 1439 MFR Date 2012-12-14

I have no information on the system other then that "one day it stopped working."

I have another Xbox 1439 MFR Date 2011-08-12 that has a slightly different motherboard layout. Despite this, I can't imagine the rf module or power brick are proprietary to that manufacturing year, so I swapped both those items that are known to work with the broken xbox, and still get the same exact results.

The power brick light is orange, and when I push either the power or eject button on the front panel all I get is their respective beeps.

The motherboard looks to be okay as far as I can see. I have never looked at one of these before but this one looks like it has a lot of empty solder pads... Perhaps they should be like that, but it doesn't make much sense to me.

Does anyone have any idea on the issue?
