I bought a new XBOX 360 S in Nov 2012 at Game Stop, part of the Holiday Bundle Deal with Skyrim, Forza, and COD or Battlefield (forget which), to replace my aging near-first generation "screamin' PSU" XBOX.
All was great initially, but then a month or so ago it started having issues powering on. I quickly figured out that if I pulled the power out of the power brick (not the XBOX, but the cable that goes from wall to power brick), let the fans stop, and then plugged it back in, it would work again for several days. Then same issue would then reoccur, and rinse/repeat.
As of the other day, the charge and play controller was no longer charged nor would the XBOX power on. Grrrr.
I finally got a chance to troubleshoot tonight and narrowed down the following:
- Unplugging all USB controllers from the front USB ports and resetting the power brick, the XBOX powers on without issue;
- Plugging in a USB connector/charging cable (I have several and tried them all) kills the power brick light, and obviously, the XBOX does not power on, ;
- Plugging in the controller with any cable to my PC (Windows 7), it's not recognized by Windows, nor does it power on or flash green lights at all;
- Using standard AA batteries in the controller(s), all works fine;
