I have a X Box 360. We use it to game and watch DVDs on my Flatscreen. Rented some movies the other day and it will not power on. I am sorry if this has been discussed, but is there a reset, or power issue with Xbox?
Do you get no fan noise? How about a light on the power adapter? Did you unplug it and plug something you know works into the same socket to verify it was not your domicile wiring that had a problem?
