Friday night was a girl's night for the wife. AHA! I'll play Xbox all evening. I turned on the Xbox with my controller and started a game. a few seconds later the controller disconnected. I reconnected and played for another couple of minutes and the controller disconnected again. OK, new batteries. This time the controller wouldn't connect at all. Power down - WT... now the box won't turn on via controller but powers up from the front panel. I've tried to get three separate controllers to work to no avail. There's no interference - the XBOX has been in its current location for about 2 years. Seems like an RF sensor issue. Anyone had this issue?
